<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"></head><body style="overflow-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">Dear Lukasz,<br><br>Thank you very much for sharing the experience and the comments.<br><br>I’m sorry that I made some mistakes in previous threads due to some of my misconceptions. I thought -fmax-stack-var-size=n moves local variables>n from stack to heap memory, but upon reading gfortran 11 documentation (<a href="https://devdocs.io/gnu_fortran~11/code-gen-options#Code-Gen-Options">https://devdocs.io/gnu_fortran~11/code-gen-options#Code-Gen-Options</a>), I realized that they actually go to static memory when > n.<br><br>It seems slightly worse than a memory leak of heap memory since they are allocated from the beginning and similarly don’t get deallocated.<br><br>It is helpful for me to know that granularity settings can help with memory leak in lapw1 when running on heterogeneous environment and there is no leak in lapwso. Thank you.<br><br>So far, I’ve only been running wien2k on normal or typically small systems, without supercell and so on, on my PC Mac, so haven’t encountered memory issues again, with a 64 GB RAM.<br><br>It is good that there are many threads in the mailing list here addressing problems of running on a slurm cluster. It will be helpful for me when I need to run something on our slurm clusters.<br><br>Best regards<br>Yichen</body></html>
