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

       # opagetvf -d Default
