Re: [mpich-discuss] Missing Nemesis ib

21 Sep 2017

      I ran the test and the result was the following:

# ./mxm_perftest

[1505976675.346380] [compute1:55801:0]         sys.c:744  MXM  WARN
Conflicting CPU frequencies detected, using: 3600.52

Waiting for connection...

It does nothing else, it remains waiting to establish connection.

I seems you have mismatch in the OFED stack. Try installing the Mellanox
OFED stack if you are using the bundled OFED stack right now.
Make sure MXM works before trying MPICH. Use the mxm/bin/mxm_perftest
from your MXM installation to test that things work properly. If it
doesn't work, then contact your admin or Mellanox cause it is not an
MPICH problem.

Thank you very much.
I have compiled with "CH3:nemesis:mxm". The compilation was successful.
Now I have a new problem. I tested the test "./icp" and get the
following error.

The "nemesis:ib" netmod does not exist anymore. Try "ch3:nemesis:mxm"
    with a dependency on Mellanox's MXM library (can be obtained from the
    HPCX package at www.mellanox.com/products/hpcx
    <http://www.mellanox.com/products/hpcx>) or "ch3:nemesis:ofi"
    with a dependency on libfabric (which would be built to support the
IB
    or MXM providers; see https://ofiwg.github.io/libfabric/).
