micprun generates micp.connect.GetOffloadIndexError

[Jim_A_2]

I've installed the micperf rpm's and am trying to trouble shoot reports of performance variance. When I try to run the "micprun" command on the michost I get this output:

[root@n1297 mpss-3.3]# micprun
Traceback (most recent call last):
  File "/usr/bin/micprun", line 311, in <module>
    devIdx = micp_connect.MPSSConnect(device).get_offload_index()
  File "/usr/src/micperf/micp-3.3/micp/connect.py", line 201, in get_offload_index
    raise GetOffloadIndexError(errStr)
micp.connect.GetOffloadIndexError: Could not determine mic index from exact match AND 
        Could not determine mic index from sysfs entries AND 
        Could not determine mic index from loose match
[root@n1297 mpss-3.3]# 

I set these environment variables  

  export PYTHONPATH=/usr/src/micperf/micp:${PYTHONPATH}

  export PATH=/usr/src/micperf/micp/micp/scripts:${PATH}

The miccheck and micinfo output looks ok, anyone have an idea what the trouble is? 

Thanks

By not specifying a particular mic card on the command line, micprun would have used mic0 and get_offload_index should have returned 0. The only thing I can think of right now is that the re module did not return the right value when it tried to pick apart 'mic0'. I can't think of why it would do that though, unless for some reason that module could not be found. But if the module is not found then the 'import re' statement in connect.py should have gotten an import error. Still this is something to try -

The re module is part of the standard Python release. Rather than relying on any default location, try specifying the locations of all the standard modules as well as the micperf modules in your PYTHONPATH variable.

Let me know what happens.

Hello Frances,

It works if I feed the hostname of the mic card to the micprun command,  the index does not work.
