Hi, George,

 

I have a problem running BW benchmark on 100 rank cluster after r18551.

The BW is mpi_p that runs mpi_bandwidth with 100K between all pairs.

 

 

#mpirun -np 100 -hostfile hostfile_w  ./mpi_p_18549 -t bw -s 100000
BW (100) (size min max avg)  100000     576.734030      2001.882416     1062.698408

#mpirun -np 100 -hostfile hostfile_w ./mpi_p_18551 -t bw -s 100000
mpirun: killing job...

( it hangs even after 10 hours ).

 

 

It doesn't happen if I run --bynode or btl openib,self only.

 

 

Lenny.
