IMB and --input, 2017.0.2

Hi,

   I've been running IMB with the following command

mpirun -n $i -genv I_MPI_DEBUG 5 -machinefile ./nodefile src/IMB-MPI1 -npmin $i -input IMB_SELECT_MPI1 -msglen ./msglens


where $i is set to 2, 4, etc., and the file IMB_SELECT_MPI1 reads

--BOF--

#

Alltoall

#

Allgather

#

Allreduce

#

Sendrecv

#

Exchange

#

Uniband

#

Biband

--EOF--

What happens is that Biband gets run 7 times, (one for each targeted test), rather than different tests as desired:

# List of Benchmarks to run:

 

# Biband

# Biband

# Biband

# Biband

# Biband

# Biband

# Biband

 

#---------------------------------------------------

# Benchmarking Biband

# #processes = 4

#---------------------------------------------------

       #bytes #repetitions   Mbytes/sec      Msg/sec

            0         1000         0.00      7199701

        65536          640     13233.43       211735

       524288           80     19708.07        39416

      4194304           10     22623.73         5656

 

#---------------------------------------------------

# Benchmarking Biband

# #processes = 4

...

Any idea why this is happening? Full stdout attached (there are some bogus runs there, but focus on the Biband output).

Thanks; Chris

Hi,

I've filed the ticket to the development team. Fix will be available for future releases of Intel(R) MPI Benchmarks.
