VASP 6.4.1 Dev Bug error
Posted: Thu Dec 07, 2023 11:48 pm
Hello everyone,
I have recently compiled VASP 6.4.1 on Lassen at LLNL which is an IBM Power9 server with V100 GPUs from Nvidia. I used NVHPC compilers which gave very little issues when following the include files which I have pasted below for reference. For the most part it seems to be performing well and giving the same values as a version we have running on an Intel cpu server. Recently while running simulations on Pu2O3 surface slab I encountered the following bug report.
I imagine that since I don't get this on my Intel build that it has to be either a choice of compiler issue or perhaps how the GPU is coded. I have pasted the POSCAR, KPOINTS, and INCAR information below as well. Please let me know any other information I can provide to assist with this debugging.

I have recently compiled VASP 6.4.1 on Lassen at LLNL which is an IBM Power9 server with V100 GPUs from Nvidia. I used NVHPC compilers which gave very little issues when following the include files which I have pasted below for reference. For the most part it seems to be performing well and giving the same values as a version we have running on an Intel cpu server. Recently while running simulations on Pu2O3 surface slab I encountered the following bug report.
