- Some users have scripts to automatize job submission. In these scripts the queue status is periodically checked. We recommend to use a frequency of at least 5 min. Example:
while True:
job_pend = calc_pending()
if job_pend < max_pend :
submit_jobs()
sleep 5 min - To know the pending jobs of a user, it is recommended to use
bjobs -u $USER –p
and avoid the use of:bjobs -u $USER | grep PEND - Please avoid the use of option
–u all, i.e. "bjobs –u all | grep <username>". Use"bjobs –u <username>"instead. - In case a huge amount of files has to be recalled from tape, it is strongly suggested to do it in agreement with Experiment Support group, which can help and facilitate the procedure.
- If you need to build a user interface from scratch you can just run the following commands on your CentOS Linux machine.
From ROOT:rm /etc/yum.repos.d/epel* /etc/yum.repos.d/UMD*
yum remove epel-release-7-11.noarch
yum install epel-release
yum install yum-priorities
yum install http://repository.egi.eu/sw/production/umd/4/centos7/x86_64/updates/umd-release-4.1.3-1.el7.centos.noarch.rpm
yum clean all
yum update
yum install ui
cat /etc/cron.d/fetch-crl; cat /usr/sbin/fetch-crl (these are to check that "cron" and the executable file called by "cron" for "fetch-crl" exist)
cat /etc/grid-security/certificates/ (this is to check that this directory contains a bunch of files in .0 and .r0 format)
