Tests

The built binaries have passed basic tests (run-tests-serial, run-tests-parallel; 4 MPI) without errors.
(You might see test failure due to the out of threshold number of iterations even when you completely follow the procedure above; due to the randomness of the initial condition.)

Notes

  • Python script in EPW directory assumes /usr/bin/python is python3. We thus modified the code slightly ("sed" line in the procedure above).
    • (Related error message "Install future. e.g. "pip install --user future" is not removed.)
  • We avoided OpenMP since that seems to be only effective for massive parallelization of huge system.
    • We tested up to 8-nodes parallel runs for OpenMP version performance. However, we couldn't get any meaningful speedup by OpenMP. There may be some advantages for further massive runs, though.
    • https://www.quantum-espresso.org/Doc/user_guide/node18.html
    • Specifying --enable-openmp has negative effect on performance for single thread runs.
    • Option such as -nk maybe the first target for performance optimization.
  • GCC 8 version met errors on some of tests.
    • Regarding performance, performance of this is comparable to intel18 version. (Intel version may be slightly faster, though.)
  • Intel 19 MPI version strangely stop running upon launching. This maybe caused by Intel MPI 19. (Intel Compiler19 + Intel MPI 18 may work. Not tested, though.)
    • Intel 17 version works fine. But that performance is slightly worse than Intel 18 version performance.
  • GPU version would be discussed in different page, since the source code repository itself is different from this one.
