Hi,

I am not sure if it related,

but I applied your patch ( r18667 ) to r 18656 ( one before NUMA ) together with disabling sendi,

The result still the same ( hanging ).

Lenny,

I guess you're running the latest version. If not, please update, Galen and myself corrected some bugs last week. If you're using the latest (and greatest) then ... well I imagine there is at least one bug left.

There is a quick test you can do. In the btl_sm.c in the module structure at the beginning of the file, please replace the sendi function by NULL. If this fix the problem, then at least we know that it's a sm send immediate problem.

Thanks,
george.

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.
