Can anybody help me to tell whether the following two processors support shared memory with MPI, i.e. the new feature launched by MPI 3.0 where each node can share memory among the cores. Intel Xeon CPU E5520 @2.27 GHz Intel Xeon CPU E5-2630 v3@2.4 GHz

I am currently getting an error whenver I launch the program with SLURM, however, if you launch on the terminal I do not get any problems?

Here is a comparison of the features of these two processors: https://ark.intel.com/content/www/us/en/ark/compare.html?productIds=83356,40200.

 

The documentation (here: https://software.intel.com/articles/intel-mpi-library-release-notes-linux#inpage-nav-3-1) indicates processor requirements as follows:

Systems based on the Intel® 64 architecture, in particular: o Intel® Core™ processor family or higher o Intel® Xeon® Scalable processor family is recommended

This would seem to indicate that it should work with any processor. Remember though that the E5520 is a much, much older (discontinued!) processor; older even that the MPI specification. I would hazard that it may not meet all of the expectations/requirements.

 

Hope this helps,
