Tests

(All the tests other than OpenMolcas are passed.)
OpenMolcas test results can be found at /local/apl/lx/openmolcas20190604/test_results .

  • i18_impi_par: tests with 2-MPI procs & 2 OMP threads
  • i18_impi_ser: serial test
  • 850_sample, 851_sample: CheMPS2 tests. (CheMPS2 PATH setting was incorrect during the serial test above.)

Serial versions didn't experience errors in "standard" and "additional" tests.
Parallel version met some numerical errors in "additional" tests and some of "additional" tests couldn't work with parallel (but test script claimed they are failed). Test 852 (in "additional" section) failed to run without clear reason.

Notes

  • Module (environment modules) name is openmolcas/20190604 .
  • Samples can be found under /local/apl/lx/openmolcas20190604/samples directory.
  • To deal with python environment of computation nodes, two python packages are placed in the installation directory and the following sentence was added to "pymolcas" script.
    • sys.path.append("/local/apl/lx/openmolcas20190604/python")
  • CheMPS2 is installed under /local/apl/lx/openmolcas20190604/chemps2 directory. If you want to invoke chemps2 from OpenMolcas, PATH must contain /local/apl/lx/openmolcas20190604/chemps2/bin.
    • (See samples. Module will also add chemps2 path when loaded.)
  • Following functions are available for Molcas but not for OpenMolcas.
    • DGA: (corresponding to GA in OpenMolcas)
      • MOLCAS_FIM: environment variable, depends on DGA.
    • CMOCORR, DIMERPERT, EMBQ, FALCON, GEO, MKNEMO, MULA, NEMO
