- Dear Prof. Ozaki,
I have a question regarding the ELPA Eigen solver.
Does the version of ELPA being incorporated in OpenMX support MPI/OpenMP hybrid?
If I compiled the program with scalapack and using MPI/OpenMP, should the speed comparable to purely MPI?
I ask this question because MPI/OpenMP hybrid is the only way to run OpenMX (cluster & 1 k-point) with limited memory for very large system.
It seems the currently available version of ELPA support MPI/OpenMP hybrid.
Thank you very much for your help.
Very best regards,
