Hi Volker

Thanks for the helpful information. I will try recompiling with OpenMPI-4.x and hopefully that will resolve these issues.
Interestingly, I had already noticed that the shared memory allocation on Durham’s COSMA7 was only 50% and had got the system admin to increase this to 95% based on your previous comments on that issue. Even so the memory table seemed to be reporting strangely low values after that reconfiguration. Anyway, we will see how things go with a new build.
