Openmpi is already loaded, and has version 4.1.0. I have seen that KB. I think i am following the right guidelines &#8211; this script I use does run the job. The main mystery is occasionally the job crashes with error &#8220;std::bad_alloc&#8221;, and as stated earlier, the job runs 90% of the time and fails 10%. The memory allocated for the job is atleast 10x what it would need (what i observe is described in more detail in the first message of this post) and the same job would not crash with a single core on local computer &#8211; just that it would take forever, so definitely not a RAM issue. But i&#8217;m unable to figure out why there is a bad_alloc and where it is happening.
