[Mvapich-discuss] MVAPICH 2.3.6 HCA Support for VMXNET3 or PVRDMA VMware Network Adapters

[Clark, Nicholas - 1002 - MITLL]

Does MVPAICH2 have support for running in VMs with VMXNET3 or the PVRDMA
network adapter that supports RoCE v1/v2?

 

Currently with the default build parameters and native rdma-core libraries
on RHEL 8.5, I am seeing this message about unknown HCA on both VMXNET3 and
PVRDMA:

 

[rdma_open_hca] Unknown HCA type: this build of MVAPICH2 does notfully
support the HCA found on the system (try with other build options)

[cli_1]: aborting job:

Fatal error in MPI_Init:

Other MPI error, error stack:

MPIR_Init_thread(493)............:

MPID_Init(419)...................: channel initialization failed

MPIDI_CH3_Init(470)..............: rdma_get_control_parameters

rdma_get_control_parameters(1925): rdma_open_hca

rdma_open_hca(1080)..............: Failed to open HCA: No such file or
directory
