Hi all, This question is not strictly related to easybuild but I supposed someone here could give me some feedback on the topic.
I am planning to upgrade my software stack (using easybuild of course :) and now I will have machines without infiniband and machines with infiniband, I would like to share the same software stack across all those machines. I am thinking about trying to compile openmpi with infiniband support (I would compile openmpi in one of the machine connected to the infiniband network) and then use this openmpi version also in the non infiniband machines. I am "expecting" that when using this version of openmpi in a non-infiniband machine openmpi will detect this and will fallback to use ethernet. Does anyone has experience with this? I am expecting correctly or this won't work? In case this is possible, is the any configuration/compilation tweaks required when building openmpi for this to work? Or am I thinking stupid stuff and I should look for a different approach? :) thanks in advance for any help.
