I don't think so. Even Intel dropped the need for DAPL in their 4.x
release. It's an extra layer between the IB stack and the MPI which
basically adds additional complexity an
Hello,
I am running into performance issue with Open MPI, I wish experts here can
provide me some help,
I have one application calls a lot of sendrecv, and isend/irecv, so waitall.
When I run Intel MPI, it is around 30% faster than OpenMPI.
However if i test sendrecv using IMB, OpenMPI is even
Dear All,
We are running a PDE solver which is memory bound. Due to
cache related issue, smaller number of grid point per core leads to
better performance for this code. Thus, though available memory per
core is more than 2 GB, we are able to good performance by using
less than 1 GB
I don't know about the grid engine/ SGE.
However, in Torque, the batch/resource manager I use,
to allow oversubscription, you need to modify the batch server nodes file
and pretend the nodes have more cores than the physical ones.
[Something like 'node01 np=8' would change to 'node01 np=16' for in
