Hi all, I am planning to upgrade my software stack 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 if possible.
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 with infiniband support enabled in a non-infiniband machine openmpi will detect this and will fallback to use ethernet. Am I expecting correctly or this won't work? Does anyone has experience with this scenario? In case this is possible, is there any configuration/compilation tweaks required when building openmpi for this to work? thanks in advance for any help. regards, Pablo. -- Pablo Escobar López HPC systems engineer Biozentrum, University of Basel Swiss Institute of Bioinformatics SIB Email: pablo.escobarlo...@unibas.ch Phone: +41 61 267 21 80 http://www.biozentrum.unibas.ch
