【求助】為什么vasp運行時cpu使用率很不均衡？ 已有4人參與
|
|
我自己編譯通過了vasp，用單節(jié)點8個cpu實驗時，發(fā)現(xiàn)第一個cpu使用率總是超過100%，甚至500%，或者800%，而第六、第七、第八個后面的cpu，利用率只有30%或50%，弄了好多次也不行。但是同樣機(jī)子上別人裝的vasp，卻能保持8個cpu都是100%的運算。 鄙人剛剛?cè)腴T，水平很菜，請各位達(dá)人給予指點，不勝感謝。 |

多謝幫忙。我在自己的個人用戶下，輸入vi ~/.bashrc，在最后加上那一行。結(jié)果仍然是一樣的，沒解決。 我發(fā)現(xiàn)可以用“mpiexec”命令實現(xiàn)并行，是不是說明機(jī)子里面裝的mpich2？？ 把我的makefile文件附在后面，如果有心情的朋友，幫忙看看吧。 .SUFFIXES: .inc .f .f90 .F #----------------------------------------------------------------------- # Makefile for Intel Fortran compiler for P4 systems # # The makefile was tested only under Linux on Intel platforms # (Suse 5.3, libc 6 <-> glibc 2.X) # # it might be required to change some of library pathes, since # LINUX installation vary a lot # Hence check ***ALL**** options in this makefile very carefully #----------------------------------------------------------------------- # # Mind that some Linux distributions (Suse 6.1) have a bug in # libm causing small errors in the error-function (total energy # is therefore wrong by about 1meV/atom).

通過你的提示，我google一下，發(fā)現(xiàn)你說的這個東西，是數(shù)學(xué)庫GotoBLAS2中的一個命令。于是，我把我安裝的GotoBLAS2整個文件夾刪除。然后重新解壓得到GotoBLAS2。進(jìn)入GotoBLAS2的目錄內(nèi)，vi Makefile.rule文件，把第41行的#NUM_THREADS=16前面的#去掉，改為NUM_THREADS=1。 然后再運行./quickbuild.64bit 。成功得到一個叫l(wèi)ibgoto2_*******.so的文件。把這個文件的目錄輸入到vasp.4.6的makefile內(nèi)。再make以后。cpu就在100%正常工作了。 多謝各位的幫忙，希望我的經(jīng)歷對大家有所幫助。  |
