Support for the RHEL7 OS distribution and clones — SL7, SLC7, Centos7 has ended. On most CICC machines (Tir2, Tir1), we are switching to Alma Linux 9 OS.
To test the JINR user environment and programs on the new OS, we have installed (so far) 2 machines:
lxui10.jinr.ru lxui11.jinr.ru
We invite all users to check the functionality and their software on these machines. We have created an environment and a set of software on them similar to machines lxpub.jinr.ru and lxui.jinr.ru .
There are some differences in the configuration of the new machines from the old lxui, lxpub.
1. Directories (nfs) will not be permanently mounted:
/opt/exp_soft/*
/local
/ftp
/cphys
/photo
/alice
/atlas
/cms
/lhcb
/salice
/slhc03
/compass
/d0
/dirac
/harp
/nemo
They will be mounted in a tree /old/ for 2-3 months, so that users can get the information they need from there.
2. Directory (nfs): /scrc —> will be mounted mounted /oldscr
There will be a new directory (nfs) /common_s, which is available at all Alma9 interactive machines.
Users need to copy their information from /oldscr to /common_s .
Directory /oldscr directory will be available for 2-3 months.
Recommendations for working with proprietary software and data.
1. We strongly recommend using EOS storage for data storage. Users can request up to 10GB of space in it. EOS is available on computers at CICC: Tier2, Tier1.
2. For specialized user group software, it is necessary to install it in CVMFS, then this software will be available on all interactive and calculating machines of CICC: Tier2, Tier1.
3. The user’s home directories at AFS ($HOME) are available on all interactive and computing machines CICC . The space in $HOME can be increased to 2GB upon user request.
Good options for working with software and data:
— HOME in AFS;
— data in EOS;
— SOFTWARE in CVMFS.
Bad options:
— SOFTWARE in EOS;
— data in AFS.
UI and computing machines translation plans.
1. UI (ui, lxpub) will be reinstalled on Alma9 OS, similar to lxui[10,11].jinr.ru by the end of May. Their names will probably be lxui[12-17].jinr.ru , or a common name — lxui.jinr.ru .
2. The batch processing system (SLURM) and calculating machines will begin reinstalling on Alma 9 OS on May 20.
3. The old NFS directories will be unavailable by mid–August. To complete the current user work, we will leave one UI machine and up to 500 cores on SL7 computing machines until mid–August.
If your software was compiled at the SL7 system and container (or apptainer) are not used, you need to add line to the job script :
#SBATCH —section=sl7
You can get and save the logfile.
To do this, add to the beginning of the script:
LOGFILE=$SLURM_SUBMIT_DIR/$SLURM_JOB_ID-final.log
#Current log file
CURLOG=$TMPDIR/$SLURM_JOB_ID.log
# Redirect stdout & strerr
exec > $CURLOG 2>&1
and at the end copy the log file:
rsync -aH $CURLOG $SLURM_SUBMIT_HOST:$LOGFILE # exit from exec exit 0
