Also if you need to search recursively below a point then:

git grep --no-index -i ${PATTERN}

will do git's grep with no need to have a git repository.  Plus it paginates, 
etc, for you.  Also pretty fast. :-)

Mahmood, good to hear you have a solution.

One learning pointgrep -i   is a good default option.  This ignores the
case of the search, so you would have found WCKey a bit faster.

Re: [slurm-users] wckey specification error

[Mahmood Naderan]

Thanks Trevor for pointing out that there is an option for such thing
is slurm.conf. Although I previously greped for *wc* and found
nothing, the correct name is TrackWCKey which is set to "yes" by
default. After setting that to "no", the error disappeared.

About the comments on Rocks and the Slurm roll... in my experiences,
rocks 7 is very good and the unofficial slurm roll provided by Werner
is also very good. It is worth to give them a try. Although I had some
experiences with manual slurm installation on an ubuntu cluster some
years ago, the automatic installation of the roll was very nice
indeed! All the commands and configurations can be extracted from the
roll. So there is no dark point about that. Limited issues about
slurm, e.g. installation, are directly related to Werner. Most of the
other question are related to the slurm itself. For example accounting
and other things.

Mahmood

The slurm-roll hosted on sourceforge is developed and supported by Werner Saar 
not by developers of Rocks and/or other Rocks application rolls (e.g. SDSC).

There is ample documentation on sourceforge[1] on how to configure your Rocks 
cluster to properly deploy the slurm-roll components and update your Slurm 
configuration.

There is also an active discussion group for the slurm-roll on sourceforge[2] 
where Werner supports users of the slurm-roll for Rocks.

While we don't use Werner's slurm-roll on our Rocks/Slurm based systems I have 
installed it on test system and can say that it works as expected/documented.

In the default configuration WCKeys were NOT enabled so this something that you 
must have added to your Slurm configuration.

If you don't need the WCKeys capability of Slurm perhaps you could simply 
disable it in your Slurm configuration.

Hope this helps,
Trevor

I quickly downloaded that roll and unpacked the RPMs.
I cannot quite see how SLurm is configured, so to my shame I gave up (I did
say that Rocks was not my thing)

I've never used it, but it sounds like you've configured your system to require 
it (or perhaps Rocks has done that?).

[slurm-users] wckey specification error

[Mahmood Naderan]

Hi,
I can not figure out why the following mpi script failed to start.

[siadati@rocks7 ~]$ sacctmgr list association
format=partition,account,user,grptres | grep siadati
   othersem1siadati  cpu=6,mem=8G
[siadati@rocks7 ~]$ cat slurm_script.sh
#!/bin/bash
#SBATCH --output=test.out
#SBATCH --job-name=lam
#SBATCH --ntasks=6
#SBATCH --partition=OTHERS
/share/apps/lammps-16Mar18/src/lmp_mpi < /share/apps/lammps-16Mar18/bench/in.lj
[siadati@rocks7 ~]$ sbatch slurm_script.sh
sbatch: error: Batch job submission failed: Invalid wckey specification
[siadati@rocks7 ~]$


The wckey explanation in the manual [1] is not meaningful at the
moment. Can someone explain that?
