“interactive” script for SLURM

I recently rolled out a new distributed model for our research computing cluster at work. We’re using GlusterFS for networked home directories and SLURM for job/resource scheduling. GlusterFS allows us to scale storage with minimal downtime or service disruption, and SLURM allows us to treat compute nodes as generic resources for running users’ jobs (ie, […]

Compile RStudio on CentOS 6

We wanted to use RStudio (an advanced IDE for R) on one of our high-memory machines at work. As our research-computing environment is a cluster of sorts (network-attached storage, with several compute nodes), I have to take extra care to install things a bit more “sustainably”; apps are installed in a non-standard prefix globally available […]

Useradd bash script for 389 LDAP

We started using 389 LDAP (aka Fedora Directory Server) for user and group management in our research computing environment. Instead of managing users, groups and passwords on each and every machine, we just put them in LDAP and have all the machines authenticate users centrally; it’s not rocket science (people have been doing centralized LDAP […]

Update ownCloud stable from tarball

When I first installed ownCloud I did a git-based install, as I like to be able to git remote update and then git merge origin/stable. This works really well for DokuWiki, WordPress, Gallery, and other web applications, but was really a pain in the ass with ownCloud; it seems the git-based workflow is really meant […]
