系统使用的Rocky Linux 9.3,环境变量里面也添加了export PGI_FASTMATH_CPU=sandybridge。结构比较大的时候,结构优化和激发态计算有的时候会报错。
结构优化的:
Logic error in AufBlk.
Error termination via Lnk1e in /home/g16/l502.exe at Sat Nov 25 23:46:24 2023.
频率计算的:
195 vectors produced by pass 0 Test12= 2.32D-13 1.00D-09 XBig12= 3.72D+03 3.92D+01.
AX will form 72 AO Fock derivatives at one time.
192 vectors produced by pass 1 Test12= 2.32D-13 1.00D-09 XBig12= 4.73D+02 5.75D+00.
OrtVc1: Ph=1 IOff= 0 IPass=20 DotMx1= 2.49+284
OrtVc1: Ph=1 M= 232443 NPass=20 Test1= 2.32D-13 Small= 2.32D-07 VSmall= 1.00D-12
OrtVc1 failed #1.
Error termination via Lnk1e in /home/g16/l1002.exe at Sat Nov 25 10:56:40 2023.
激发态计算的,数值是NaN,激发态能量也没给出来
Iteration 2 Dimension 180 NMult 120 NNew 60
CISAX will form 60 AO SS matrices at one time.
NMat= 60 NSing= 60 JSym2X= 0.
SlvRan: Skip vector 1 energy NaN DEMCon -1.000000D+20
SlvRan: Skip vector 2 energy NaN DEMCon -1.000000D+20
SlvRan: Skip vector 3 energy NaN DEMCon -1.000000D+20
相同的计算文件在Intel平台(i3-12100, Rocky Linux 9.3)上没有出错
考虑是不是7950x用的Linux系统太新了,Gaussian给的兼容列表只到Red Hat Enterprise Linux 5.11, 6.10, 7.6, 8.3
