A really thin web layer above SLURM

Current home is https://github.com/dragz/slurmbrowser/

bottle.py and access to the slurm commands scontrol, squeue and sacct.

yum -y install python2-bottle

For a quick test run

python slurmdata.py

and point your browser to:

http://localhost:9080/html/squeue.html

It will listen on localhost:9080 in dev mode.

Put it under the wings of apache. See apache_wsgi/ for example configs.

mod_wsgi is needed

yum -y install mod_wsgi

It is possible to fetch graphs from ganglia which gives a very nice interface for the user to check the status of their jobs both live and in retrospect. See slurmbrowser.cfg for hints on how to enable this (off by default as more work is needed on describing this integration).

Make jobs clickable so the row will expand with more info. Something like this https://datatables.net/examples/api/row_details.html

Add load graphs like the old torque jobbrowser. (done)

More global info

The basic principle is to make all slurm commands produce csv-parsable output and let bottle convert it to json upon client requests. The server is only handing out json data and static html files (albeit with lots of included javascript). The server does not do any data layout rendering, that is all left to the client.

Not really an API

/data/job/XXXX Return the output of

scontrol show -d --onliner job XXXX

/data/nodeinfo Return the output of

scontrol show -d --oneline node

/data/squeue Return the output of

squeue -o %all

Remark: This also creates an extra entry, FULL_NODELIST, containing an expanded nodelist. c[1-4] -> c1,c2,c3,c4. Don`t know how to do this in javascript yet...

/data/jobhist/USER Return the output of

sacct -S YYYY-MM-DD -X --format=jobid,jobname,user,account,state,elapsed,start,end,nnodes,ncpus,nodelist --parsable2 -u USER

The client side is based on async fetching of json data from the server and all (or most) rendering of data is done by using the DataTables library. The client is responsible to interpret and display the data.
