Hi openmpi'users
I now trying to install mrmpi in a cluster to use it with openmpi, I installed
locally openmpi with the option --disable-dlopen , I install also mrmpi without
apparent problems but when testing with the basic commands in a python27 shell
What is mrmpi?
from mrmpi import mrmpi
mr=mrmpi()
I get the following warning, and shell stays waiting without response….
libibverbs: Warning: no userspace device-specific driver found for
/sys/class/infiniband_verbs/uverbs0
Looks like OMPI was built with Infiniband support, but we aren't finding the required
support libraries wherever the process is running. They were probably present on the
machine where you built OMPI. You should check the remote node, and either install the
libraries there or re-configure OMPI to ignore inifiniband. See "./configure
-h" to find the relevant IB option - I think it is --without-openib
Help please!
