Hi,
Try waiting on all gathers at the same time, not one by one (this is
what non blocking collectives are made for!)
Cheers,

Hi,
I'm testing the non-blocking collective of OpenMPI-1.8.
I have two nodes with Infiniband to perform allgather on totally 128MB data.
I split the 128MB data into eight pieces, and perform computation and
MPI_Iallgatherv() on one piece of data each iteration, hoping that the
MPI_Iallgatherv()
Mpirun *--mca btl ^openib --mca btl_tcp_if_include eth0* -np 16
-machinefile mf mpiblast -d all.fas -p blastn -i query.fas -o out.txt
was the command i executed on cluster...
