【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。 ******************* #! /bin/sh # courtesy of Jarek Nieplocha, to clean ipc's # Modified by Bill Gropp to apply only to calling user ipccmd=ipcrm for arg in "$@" ; do case $arg in -help|-u|-us*|-h) echo "cleanipcs [-show] [-echo]" exit 1 ;; -echo) set -x ;; -show) ipccmd="echo ipcrm" ;; *) if [ -n "$arg" ] ; then echo "Unrecognized argument $arg" exit 1 fi ;; esac done # # LINUX uses an incompatible form of the ipcrm command! Try to detect this # An earlier version looked at the output of ipcrm, but that output # keeps changing. The following code from Ralf Wildenhues attempts to # use the Linux /proc interface. #statvalue=`ipcrm 2>&1` #if [ $? != 0 ] ; then # if [ "$statvalue" = 'usage: ipcrm [shm | msg | sem] id' ] ; then # UseLinux=1 # fi #fi #if [ $UseLinux = 0 ] ; then if [ x`uname -s` = xLinux ] ; then # try to use /proc interface if possible # and hope it does not change too often if [ -r /proc/sysvipc/shm ] ; then cat /proc/sysvipc/shm \ | gawk '{if ($8 == uid) printf("%s %s\n", comm, $2)}' uid=$UID comm="$ipccmd shm " \ | sh > /dev/null else ipcs -m \ | gawk '{if ($3 == name) printf("%s %s\n", comm, $2)}' name=$LOGNAME comm="$ipccmd shm " \ | sh > /dev/null fi if [ -r /proc/sysvipc/sem ] ; then cat /proc/sysvipc/sem \ | gawk '{if ($5 == uid) printf("%s %s\n", comm, $2)}' uid=$UID comm="$ipccmd sem " \ | sh > /dev/null else ipcs -s \ | gawk '{if ($3 == name) printf("%s %s\n", comm, $2)}' name=$LOGNAME comm="$ipccmd sem " \ | sh > /dev/null fi else $ipccmd `ipcs | awk '{if ((($1 == "m"  || ($1 == "s") && ($5 == "'$LOGNAME'") print sprintf("-%s %s",$1,$2) }'`fi # # Here is the old LINUX code # # # # For LINUX, we need this instead: # ipcs -m | gawk '{if ($3 == name) printf("%s %s\n", comm, $2)}' name=$LOGNAME comm="$ipccmd shm " | sh > /dev/null # 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. ******************* [ Last edited by mingdong on 2009-9-14 at 16:58 ] |
