Dear developers,
I have successfully compiled vtstcode6.1 (at VTST-188 folder) with OpenACC version of VASP 6.1.0. However, I met a problem when I ran the vasp_std (mpirun -n 2 --allow-run-as-root /usr/local/vasp.6.1.0.vtst/bin/vasp_std) on a machine with 2 V100, which only one V100 was used, the Volatile GPU-Util of the other V100 is 0. Please see the Attachments.
Could someone help me please?
Best regrads,
Ming
