now for different supercomputers

I already shared my now script intended for a small “in home” computing cluster. This time, I am sharing two other variations of that script, designed for the queuing systems of two different supercomputers: Mare Nostrum at BSC, Juropa at JSC and HLRN.

Both of them are the predecessors of the newer now script, and they only have the very basic features, but if you need an script that works right out of the box for any of the supercomputers mentioned above, this is the quick solution.

now: easy job monitoring

Performing job monitoring tasks while running jobs on a cluster/supercomputer can be done by several tools (such as qstat, showstart, …). Unfortunately the most of these standard tools are made by computer scientist for computer scientists, but now, there is an alternative: now.
At some point in my life, I started to get sick of qstats, greps, awks, … because it takes a couple of seconds every time one has to write them. If we multiply these seconds by the number of times I need them and by the number of computational members in my group, we get enough time to prepare a couple of new inputs, or write some post/comments in my blog.
So, I wrote my own job monitoring/visualization script, based on some ideas of my friend Iñaki during my time in the theoretical chemistry group in Donostia. That script, initially did nothing but execute these programs and display ONLY the information I need, and ALL the information I need. This information includes: Continue reading
