NAME

       opagetvf

       Used  for  scripting  application  use of vFabrics, such as for mpirun parameters. You can
       query by VF Name, VF Index, Service ID, MGID, PKey, or SL. Fetches the Virtual Fabric info
       in a delimited format. Returns exactly one matching VF. When multiple VFs match the query,
       it prefers non-default VFs in which the calling server  is  a  full  member.  If  multiple
       choices  remain,  it  returns the one with the lowest VF Index. Uses the same algorithm as
       the Distributed SA Plug-in (DSAP).

       The tool can be used with additional scripts to help set PKey,  SL,  MTU,  and  Rate  when
       running  MPI  jobs. Internally, this tool is based on the opasaquery -o vfinfocsv command.
       For more information, see opasaquery

Syntax

       opagetvf [-h  hfi] [-p  port] [-e] [-d  vfname | -S  serviceId | -m  mcgid |

       -i  vfIndex | -k  pkey | -L  sl]

Options

       --help

                 Produces full help text.

       -h hfi

                 Specifies the HFI to send by. Default is first HFI.

       -p port

                 Specifies the port to send by. Default is first active port.

       -e

                 Outputs MTU and rate as enum values.

       -d vfname

                 Queries by VirtualFabric Name.

       -S serviceId

                 Queries by Application ServiceId.

       -m gid

                 Queries by Application Multicast GID.

       -i vfindex

                 Queries by VirtualFabric Index.

       -k pkey

                 Queries by VirtualFabric PKey.

       -L SL

                 Queries by VirtualFabric SL.

Examples

       opagetvf -d 'Compute'

       opagetvf -h 2 -p 2 -d 'Compute'

Sample Outputs

       The output is of the form: name:index:pkey:sl:mtu:rate:optionflag::mcastSl as shown in the
       following example.

       Option flag (bitmask) values include:

       •      0x00  Indicates  no  bits  are  set. Specifically, no QoS, no Security, and no flow
              control disabled (which means flow control is enabled).

       •      0x01 Security

       •      0x02 QoS

       •      0x04 Flow Control Disable
