application programming interface.
Function Documentation
CUresult cuFuncGetAttribute (int * pi, CUfunction_attribute attrib, CUfunction hfunc)
Returns in *pi the integer value of the attribute attrib on the kernel given by hfunc. The
supported attributes are:
• CU_FUNC_ATTRIBUTE_MAX_THREADS_PER_BLOCK: The maximum number of threads per block, beyond
which a launch of the function would fail. This number depends on both the function and
the device on which the function is currently loaded.
• CU_FUNC_ATTRIBUTE_SHARED_SIZE_BYTES: The size in bytes of statically-allocated shared
memory per block required by this function. This does not include dynamically-allocated
shared memory requested by the user at runtime.
• CU_FUNC_ATTRIBUTE_CONST_SIZE_BYTES: The size in bytes of user-allocated constant memory
required by this function.
• CU_FUNC_ATTRIBUTE_LOCAL_SIZE_BYTES: The size in bytes of local memory used by each
thread of this function.
• CU_FUNC_ATTRIBUTE_NUM_REGS: The number of registers used by each thread of this
function.
• CU_FUNC_ATTRIBUTE_PTX_VERSION: The PTX virtual architecture version for which the
function was compiled. This value is the major PTX version * 10 + the minor PTX version,
so a PTX version 1.3 function would return the value 13. Note that this may return the
undefined value of 0 for cubins compiled prior to CUDA 3.0.
• CU_FUNC_ATTRIBUTE_BINARY_VERSION: The binary architecture version for which the function
was compiled. This value is the major binary version * 10 + the minor binary version, so
a binary version 1.3 function would return the value 13. Note that this will return a
value of 10 for legacy cubins that do not have a properly-encoded binary architecture
version.
• CU_FUNC_CACHE_MODE_CA: The attribute to indicate whether the function has been compiled
with user specified option '-Xptxas --dlcm=ca' set .
• CU_FUNC_ATTRIBUTE_MAX_DYNAMIC_SHARED_SIZE_BYTES: The maximum size in bytes of
dynamically-allocated shared memory.
• CU_FUNC_ATTRIBUTE_PREFERRED_SHARED_MEMORY_CARVEOUT: Preferred shared memory-L1 cache
split ratio in percent of shared memory.
Parameters:
pi - Returned attribute value
attrib - Attribute requested
hfunc - Function to query attribute of
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,
CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_INVALID_VALUE
Note:
Note that this function may also return error codes from previous, asynchronous
launches.
See also:
cuCtxGetCacheConfig, cuCtxSetCacheConfig, cuFuncSetCacheConfig, cuLaunchKernel,
cudaFuncGetAttributes cudaFuncSetAttribute
CUresult cuFuncSetAttribute (CUfunction hfunc, CUfunction_attribute attrib, int value)
This call sets the value of a specified attribute attrib on the kernel given by hfunc to
an integer value specified by val This function returns CUDA_SUCCESS if the new value of
the attribute could be successfully set. If the set fails, this call will return an error.
Not all attributes can have values set. Attempting to set a value on a read-only attribute
will result in an error (CUDA_ERROR_INVALID_VALUE)
Supported attributes for the cuFuncSetAttribute call are:
• CU_FUNC_ATTRIBUTE_MAX_DYNAMIC_SHARED_SIZE_BYTES: This maximum size in bytes of
dynamically-allocated shared memory. The value should contain the requested maximum size
of dynamically-allocated shared memory. The sum of this value and the function attribute
CU_FUNC_ATTRIBUTE_SHARED_SIZE_BYTES cannot exceed the device attribute
CU_DEVICE_ATTRIBUTE_MAX_SHARED_MEMORY_PER_BLOCK_OPTIN. The maximal size of requestable
dynamic shared memory may differ by GPU architecture.
• CU_FUNC_ATTRIBUTE_PREFERRED_SHARED_MEMORY_CARVEOUT: On devices where the L1 cache and
shared memory use the same hardware resources, this sets the shared memory carveout
preference, in percent of the total resources. This is only a hint, and the driver can
choose a different ratio if required to execute the function.
Parameters:
hfunc - Function to query attribute of
attrib - Attribute requested
value - The value to set
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,
CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_INVALID_VALUE
Note:
Note that this function may also return error codes from previous, asynchronous
launches.
See also:
cuCtxGetCacheConfig, cuCtxSetCacheConfig, cuFuncSetCacheConfig, cuLaunchKernel,
cudaFuncGetAttributes cudaFuncSetAttribute
CUresult cuFuncSetCacheConfig (CUfunction hfunc, CUfunc_cache config)
On devices where the L1 cache and shared memory use the same hardware resources, this sets
through config the preferred cache configuration for the device function hfunc. This is
only a preference. The driver will use the requested configuration if possible, but it is
free to choose a different configuration if required to execute hfunc. Any context-wide
preference set via cuCtxSetCacheConfig() will be overridden by this per-function setting
unless the per-function setting is CU_FUNC_CACHE_PREFER_NONE. In that case, the current
context-wide setting will be used.
This setting does nothing on devices where the size of the L1 cache and shared memory are
fixed.
Launching a kernel with a different preference than the most recent preference setting may
insert a device-side synchronization point.
The supported cache configurations are:
• CU_FUNC_CACHE_PREFER_NONE: no preference for shared memory or L1 (default)
• CU_FUNC_CACHE_PREFER_SHARED: prefer larger shared memory and smaller L1 cache
• CU_FUNC_CACHE_PREFER_L1: prefer larger L1 cache and smaller shared memory
• CU_FUNC_CACHE_PREFER_EQUAL: prefer equal sized L1 cache and shared memory
Parameters:
hfunc - Kernel to configure cache for
config - Requested cache configuration
Returns:
CUDA_SUCCESS, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_DEINITIALIZED,
CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT
Note:
Note that this function may also return error codes from previous, asynchronous
launches.

CUresult cuFuncSetSharedMemConfig (CUfunction hfunc, CUsharedconfig config)
On devices with configurable shared memory banks, this function will force all subsequent
launches of the specified device function to have the given shared memory bank size
configuration. On any given launch of the function, the shared memory configuration of the
device will be temporarily changed if needed to suit the function's preferred
configuration. Changes in shared memory configuration between subsequent launches of
functions, may introduce a device side synchronization point.
Any per-function setting of shared memory bank size set via cuFuncSetSharedMemConfig will
override the context wide setting set with cuCtxSetSharedMemConfig.
Changing the shared memory bank size will not increase shared memory usage or affect
occupancy of kernels, but may have major effects on performance. Larger bank sizes will
allow for greater potential bandwidth to shared memory, but will change what kinds of
accesses to shared memory will result in bank conflicts.
This function will do nothing on devices with fixed shared memory bank size.
The supported bank configurations are:
• CU_SHARED_MEM_CONFIG_DEFAULT_BANK_SIZE: use the context's shared memory configuration
when launching this function.
• CU_SHARED_MEM_CONFIG_FOUR_BYTE_BANK_SIZE: set shared memory bank width to be natively
four bytes when launching this function.
• CU_SHARED_MEM_CONFIG_EIGHT_BYTE_BANK_SIZE: set shared memory bank width to be natively
eight bytes when launching this function.
Parameters:
hfunc - kernel to be given a shared memory config
config - requested shared memory configuration
Returns:
CUDA_SUCCESS, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_DEINITIALIZED,
CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT
Note:
Note that this function may also return error codes from previous, asynchronous
launches.

CUresult cuLaunchCooperativeKernel (CUfunction f, unsigned int gridDimX, unsigned int
gridDimY, unsigned int gridDimZ, unsigned int blockDimX, unsigned int blockDimY, unsigned
int blockDimZ, unsigned int sharedMemBytes, CUstream hStream, void ** kernelParams)
Invokes the kernel f on a gridDimX x gridDimY x gridDimZ grid of blocks. Each block
contains blockDimX x blockDimY x blockDimZ threads.
sharedMemBytes sets the amount of dynamic shared memory that will be available to each
thread block.
The device on which this kernel is invoked must have a non-zero value for the device
attribute CU_DEVICE_ATTRIBUTE_COOPERATIVE_LAUNCH.
The total number of blocks launched cannot exceed the maximum number of blocks per
multiprocessor as returned by cuOccupancyMaxActiveBlocksPerMultiprocessor (or
cuOccupancyMaxActiveBlocksPerMultiprocessorWithFlags) times the number of multiprocessors
as specified by the device attribute CU_DEVICE_ATTRIBUTE_MULTIPROCESSOR_COUNT.
The kernel cannot make use of CUDA dynamic parallelism.
Kernel parameters must be specified via kernelParams. If f has N parameters, then
kernelParams needs to be an array of N pointers. Each of kernelParams[0] through
kernelParams[N-1] must point to a region of memory from which the actual kernel parameter
will be copied. The number of kernel parameters and their offsets and sizes do not need to
be specified as that information is retrieved directly from the kernel's image.
Calling cuLaunchCooperativeKernel() sets persistent function state that is the same as
function state set through cuLaunchKernel API
When the kernel f is launched via cuLaunchCooperativeKernel(), the previous block shape,
shared size and parameter info associated with f is overwritten.
Note that to use cuLaunchCooperativeKernel(), the kernel f must either have been compiled
with toolchain version 3.2 or later so that it will contain kernel parameter information,
or have no kernel parameters. If either of these conditions is not met, then
cuLaunchCooperativeKernel() will return CUDA_ERROR_INVALID_IMAGE.
Parameters:
f - Kernel to launch
gridDimX - Width of grid in blocks
gridDimY - Height of grid in blocks
gridDimZ - Depth of grid in blocks
blockDimX - X dimension of each thread block
blockDimY - Y dimension of each thread block
blockDimZ - Z dimension of each thread block
sharedMemBytes - Dynamic shared-memory size per thread block in bytes
hStream - Stream identifier
kernelParams - Array of pointers to kernel parameters
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,
CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_INVALID_IMAGE,
CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_LAUNCH_FAILED,
CUDA_ERROR_LAUNCH_OUT_OF_RESOURCES, CUDA_ERROR_LAUNCH_TIMEOUT,
CUDA_ERROR_LAUNCH_INCOMPATIBLE_TEXTURING, CUDA_ERROR_COOPERATIVE_LAUNCH_TOO_LARGE,
CUDA_ERROR_SHARED_OBJECT_INIT_FAILED
Note:
This function uses standard semantics.
Note that this function may also return error codes from previous, asynchronous
launches.

cuLaunchCooperativeKernelMultiDevice, cudaLaunchCooperativeKernel
CUresult cuLaunchCooperativeKernelMultiDevice (CUDA_LAUNCH_PARAMS * launchParamsList, unsigned
int numDevices, unsigned int flags)
Invokes kernels as specified in the launchParamsList array where each element of the array
specifies all the parameters required to perform a single kernel launch. These kernels can
cooperate and synchronize as they execute. The size of the array is specified by
numDevices.
No two kernels can be launched on the same device. All the devices targeted by this multi-
device launch must be identical. All devices must have a non-zero value for the device
attribute CU_DEVICE_ATTRIBUTE_COOPERATIVE_MULTI_DEVICE_LAUNCH.
All kernels launched must be identical with respect to the compiled code. Note that any
__device__, __constant__ or __managed__ variables present in the module that owns the
kernel launched on each device, are independently instantiated on every device. It is the
application's responsibility to ensure these variables are initialized and used
appropriately.
The size of the grids as specified in blocks, the size of the blocks themselves and the
amount of shared memory used by each thread block must also match across all launched
kernels.
The streams used to launch these kernels must have been created via either cuStreamCreate
or cuStreamCreateWithPriority. The NULL stream or CU_STREAM_LEGACY or CU_STREAM_PER_THREAD
cannot be used.
The total number of blocks launched per kernel cannot exceed the maximum number of blocks
per multiprocessor as returned by cuOccupancyMaxActiveBlocksPerMultiprocessor (or
cuOccupancyMaxActiveBlocksPerMultiprocessorWithFlags) times the number of multiprocessors
as specified by the device attribute CU_DEVICE_ATTRIBUTE_MULTIPROCESSOR_COUNT. Since the
total number of blocks launched per device has to match across all devices, the maximum
number of blocks that can be launched per device will be limited by the device with the
least number of multiprocessors.
The kernels cannot make use of CUDA dynamic parallelism.
The CUDA_LAUNCH_PARAMS structure is defined as:
typedef struct CUDA_LAUNCH_PARAMS_st
{
CUfunction function;
unsigned int gridDimX;
unsigned int gridDimY;
unsigned int gridDimZ;
unsigned int blockDimX;
unsigned int blockDimY;
unsigned int blockDimZ;
unsigned int sharedMemBytes;
CUstream hStream;
void **kernelParams;
} CUDA_LAUNCH_PARAMS;
where:
• CUDA_LAUNCH_PARAMS::function specifies the kernel to be launched. All functions must be
identical with respect to the compiled code.
• CUDA_LAUNCH_PARAMS::gridDimX is the width of the grid in blocks. This must match across
all kernels launched.
• CUDA_LAUNCH_PARAMS::gridDimY is the height of the grid in blocks. This must match across
all kernels launched.
• CUDA_LAUNCH_PARAMS::gridDimZ is the depth of the grid in blocks. This must match across
all kernels launched.
• CUDA_LAUNCH_PARAMS::blockDimX is the X dimension of each thread block. This must match
across all kernels launched.
• CUDA_LAUNCH_PARAMS::blockDimX is the Y dimension of each thread block. This must match
across all kernels launched.
• CUDA_LAUNCH_PARAMS::blockDimZ is the Z dimension of each thread block. This must match
across all kernels launched.
• CUDA_LAUNCH_PARAMS::sharedMemBytes is the dynamic shared-memory size per thread block in
bytes. This must match across all kernels launched.
• CUDA_LAUNCH_PARAMS::hStream is the handle to the stream to perform the launch in. This
cannot be the NULL stream or CU_STREAM_LEGACY or CU_STREAM_PER_THREAD. The CUDA context
associated with this stream must match that associated with
CUDA_LAUNCH_PARAMS::function.
• CUDA_LAUNCH_PARAMS::kernelParams is an array of pointers to kernel parameters. If
CUDA_LAUNCH_PARAMS::function has N parameters, then CUDA_LAUNCH_PARAMS::kernelParams
needs to be an array of N pointers. Each of CUDA_LAUNCH_PARAMS::kernelParams[0] through
CUDA_LAUNCH_PARAMS::kernelParams[N-1] must point to a region of memory from which the
actual kernel parameter will be copied. The number of kernel parameters and their
offsets and sizes do not need to be specified as that information is retrieved directly
from the kernel's image.
By default, the kernel won't begin execution on any GPU until all prior work in all the
specified streams has completed. This behavior can be overridden by specifying the flag
CUDA_COOPERATIVE_LAUNCH_MULTI_DEVICE_NO_PRE_LAUNCH_SYNC. When this flag is specified, each
kernel will only wait for prior work in the stream corresponding to that GPU to complete
before it begins execution.
Similarly, by default, any subsequent work pushed in any of the specified streams will not
begin execution until the kernels on all GPUs have completed. This behavior can be
overridden by specifying the flag
CUDA_COOPERATIVE_LAUNCH_MULTI_DEVICE_NO_POST_LAUNCH_SYNC. When this flag is specified, any
subsequent work pushed in any of the specified streams will only wait for the kernel
launched on the GPU corresponding to that stream to complete before it begins execution.
Calling cuLaunchCooperativeKernelMultiDevice() sets persistent function state that is the
same as function state set through cuLaunchKernel API when called individually for each
element in launchParamsList.
When kernels are launched via cuLaunchCooperativeKernelMultiDevice(), the previous block
shape, shared size and parameter info associated with each CUDA_LAUNCH_PARAMS::function in
launchParamsList is overwritten.
Note that to use cuLaunchCooperativeKernelMultiDevice(), the kernels must either have been
compiled with toolchain version 3.2 or later so that it will contain kernel parameter
information, or have no kernel parameters. If either of these conditions is not met, then
cuLaunchCooperativeKernelMultiDevice() will return CUDA_ERROR_INVALID_IMAGE.
Parameters:
launchParamsList - List of launch parameters, one per device
numDevices - Size of the launchParamsList array
flags - Flags to control launch behavior
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,
CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_INVALID_IMAGE,
CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_LAUNCH_FAILED,
CUDA_ERROR_LAUNCH_OUT_OF_RESOURCES, CUDA_ERROR_LAUNCH_TIMEOUT,
CUDA_ERROR_LAUNCH_INCOMPATIBLE_TEXTURING, CUDA_ERROR_COOPERATIVE_LAUNCH_TOO_LARGE,
CUDA_ERROR_SHARED_OBJECT_INIT_FAILED
Note:
This function uses standard semantics.
Note that this function may also return error codes from previous, asynchronous
launches.

CUresult cuLaunchKernel (CUfunction f, unsigned int gridDimX, unsigned int gridDimY, unsigned
int gridDimZ, unsigned int blockDimX, unsigned int blockDimY, unsigned int blockDimZ,
unsigned int sharedMemBytes, CUstream hStream, void ** kernelParams, void ** extra)
Invokes the kernel f on a gridDimX x gridDimY x gridDimZ grid of blocks. Each block
contains blockDimX x blockDimY x blockDimZ threads.
sharedMemBytes sets the amount of dynamic shared memory that will be available to each
thread block.
Kernel parameters to f can be specified in one of two ways:
1) Kernel parameters can be specified via kernelParams. If f has N parameters, then
kernelParams needs to be an array of N pointers. Each of kernelParams[0] through
kernelParams[N-1] must point to a region of memory from which the actual kernel parameter
will be copied. The number of kernel parameters and their offsets and sizes do not need to
be specified as that information is retrieved directly from the kernel's image.
2) Kernel parameters can also be packaged by the application into a single buffer that is
passed in via the extra parameter. This places the burden on the application of knowing
each kernel parameter's size and alignment/padding within the buffer. Here is an example
of using the extra parameter in this manner:
size_t argBufferSize;
char argBuffer[256];
// populate argBuffer and argBufferSize
void *config[] = {
CU_LAUNCH_PARAM_BUFFER_POINTER, argBuffer,
CU_LAUNCH_PARAM_BUFFER_SIZE, &argBufferSize,
CU_LAUNCH_PARAM_END
};
status = cuLaunchKernel(f, gx, gy, gz, bx, by, bz, sh, s, NULL, config);
The extra parameter exists to allow cuLaunchKernel to take additional less commonly used
arguments. extra specifies a list of names of extra settings and their corresponding
values. Each extra setting name is immediately followed by the corresponding value. The
list must be terminated with either NULL or CU_LAUNCH_PARAM_END.
• CU_LAUNCH_PARAM_END, which indicates the end of the extra array;
• CU_LAUNCH_PARAM_BUFFER_POINTER, which specifies that the next value in extra will be a
pointer to a buffer containing all the kernel parameters for launching kernel f;
• CU_LAUNCH_PARAM_BUFFER_SIZE, which specifies that the next value in extra will be a
pointer to a size_t containing the size of the buffer specified with
CU_LAUNCH_PARAM_BUFFER_POINTER;
The error CUDA_ERROR_INVALID_VALUE will be returned if kernel parameters are specified
with both kernelParams and extra (i.e. both kernelParams and extra are non-NULL).
Calling cuLaunchKernel() sets persistent function state that is the same as function state
set through the following deprecated APIs: cuFuncSetBlockShape(), cuFuncSetSharedSize(),
cuParamSetSize(), cuParamSeti(), cuParamSetf(), cuParamSetv().
When the kernel f is launched via cuLaunchKernel(), the previous block shape, shared size
and parameter info associated with f is overwritten.
Note that to use cuLaunchKernel(), the kernel f must either have been compiled with
toolchain version 3.2 or later so that it will contain kernel parameter information, or
have no kernel parameters. If either of these conditions is not met, then cuLaunchKernel()
will return CUDA_ERROR_INVALID_IMAGE.
Parameters:
f - Kernel to launch
gridDimX - Width of grid in blocks
gridDimY - Height of grid in blocks
gridDimZ - Depth of grid in blocks
blockDimX - X dimension of each thread block
blockDimY - Y dimension of each thread block
blockDimZ - Z dimension of each thread block
sharedMemBytes - Dynamic shared-memory size per thread block in bytes
hStream - Stream identifier
kernelParams - Array of pointers to kernel parameters
extra - Extra options
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,
CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_INVALID_IMAGE,
CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_LAUNCH_FAILED,
CUDA_ERROR_LAUNCH_OUT_OF_RESOURCES, CUDA_ERROR_LAUNCH_TIMEOUT,
CUDA_ERROR_LAUNCH_INCOMPATIBLE_TEXTURING, CUDA_ERROR_SHARED_OBJECT_INIT_FAILED
Note:
This function uses standard semantics.
Note that this function may also return error codes from previous, asynchronous
launches.
