Notes

  • Built and tested on ccgpuv.
    • Non-PME tests (9 of REMD tests) failed since GPU version supports only PME. This is totally expected.
    • All the other tests were passed successfully.
  • Single "spdyn" binary works both on P100 and V100 (confirmed on ccgpup and ccgpuv).
  • The build system specifies PTX and cubin versions of 35, 37, and 61. V100 (compute capability 7.0) might not be natively supported.
    • Strictly, P100 (compute capability 6.0) is not natively supported?
