使用A100-80G 做VASP6.4.1的GPU加速,经常会遇到real time是cpu time的二倍,百思不得其解,尚未找到能修正这个问题的解决方式。
grep LOOP OUTCAR
LOOP: cpu time 12.4413: real time 24.8912
LOOP: cpu time 11.7627: real time 23.5531
LOOP: cpu time 11.7497: real time 23.5035
LOOP: cpu time 12.5075: real time 25.0248
LOOP: cpu time 14.9064: real time 29.8451
LOOP: cpu time 16.9084: real time 33.8327
LOOP: cpu time 16.7066: real time 33.4186
