EPW Forum

Dear all,

I am running the MgB2 example as given in the examples.

In the epw part, the code started running, and after some time, it stuck
at some point without quitting the job. However, it is running successfully
in serial.
I installed the qe-7.2 using intel one API.

I have attached the necessary files.

Could anyone please point out the possible reason for this?

With regards,

Hi Bikash,

It looks like a memory issue. Could you please run test-suite/epw_super? https://gitlab.com/QEF/q-e/-/tree/devel ... /epw_super. To run this, you can issue "make run-custom-test-parallel testdir=epw_super" inside qe/test-suite directory.

If it passes through, it will confirm that your system do not have enough memory to handle the k/q points used in your current input.

Happy EPWing,
Hari
