unable to write Lammps dump files

[asif1]

Hi,

I have compiled the latest version of Lammps using gcc with intel-onepi-mpi successfully, I am writing dump and restart files at certain iterations during lammps run. The job will start and run fine, but the job will stop to write the dump file and continues to run using 100% of cpu, no error or output message gets updated. The job just hangs, I have no issues running the job using openmpi. Any help is appreciated.

Thanks,

Asif.

Hi,

Thank you for your inquiry. We can only offer direct support for Intel hardware platforms that the Intel® oneAPI product supports. Intel provides instructions on how to compile oneAPI code for both CPU and a wide range of GPU accelerators.

https://intel.github.io/llvm-docs/GetStartedGuide.html

We can see that your processor and operating system don't meet the Intel MPI system requirements. We recommend you try using an Intel processor & supported operating system as mentioned in the below system requirements page:

If you still face the same issue, then please provide us with a sample reproducer code to investigate your issue from our end.

Thanks & Regards,
