[交流] 【交流】pc-gamess for linux出现semget failed问题的解决办法

如果多次杀死pc-gamess的进程，经常会导致后面的pc-gamess任务无法正常提交，在输出文件中出现如下的出错信息：

p0_30545:  p4_error: semget failed for setnum: 8

这是某些通信端口没有正常关闭造成的。在网上找到了解决办法：把以下命令（两行星号之间）存成可执行的脚本文件，并运行。

这个脚本仅对pc-gamess有效，对gamess-us不起作用。

# ipcs -s | gawk '{if ($3 == name) printf("%s %s\n", comm, $2)}' name=$LOGNAME comm="$ipccmd sem " | sh > /dev/null

# mpirun could call this for systems that use SYSV shared memory features,
# just to keep them friendly.
