[mvapich-discuss] MV2_USE_BLOCKING in local host without IB device

[RIVERA ROLDAN, Jorge Orlando]

Hello

I have compiled  an application  to run with mvapich in a host with  Infiniband .

When I  tried to run the same application on a local host(wo Infiniband)   I had to copy the infiniband libraries to the PATH

Getting the expected warning

librdmacm: couldn't read ABI version.
librdmacm: assuming: 4

and it was working well  ,

later I have set    MV2_USE_BLOCKING=1 on this host without Infiniband adapter ,  My application is an interactive one  and I would  like to
reduce the CPU utilization . However  I get this error

[cli_6]: aborting job:
Fatal error in MPI_Init:
Other MPI error, error stack:
MPIR_Init_thread(514)............:
MPID_Init(363)...................: channel initialization failed
MPIDI_CH3_Init(391)..............:
MPIDI_CH3I_RDMA_init(181)........:
rdma_get_control_parameters(1305):
rdma_open_hca(517)...............: No IB device found


It is possible to  set the another adapter   or to use Block Mode in a host without IB device ?

Thanks

Orlando Rivera
