Grid Engine Job Submission Verifier (JSV) using Go

on Thu, 04/24/2014 - 13:22

Posted by David Chin

Dan Gruber at Univa wrote a Go API for Univa Grid Engine job submission verifiers (JSV). His testing indicated that it was a fair bit faster than TCL or Perl, the recommended JSV languages for a production environment.

I decided it was a good enough time as any to dabble a little in Go, seeing as I had a simple problem to solve. Users occasionally make mistakes, and submit parallel jobs without requesting a parallel environment with the appropriate number of slots.

Client Side JSV Performance Comparison - And the Wimmer is: GO (#golang)

on Thu, 04/24/2014 - 13:13

With JSV scripts you can verify and change your job submission parameters. Depending on the called functions you can also reject jobs which does not follow rules you specify in the script. Those JSV scripts can be installed globally on the qmaster (qconf -mconf / jsv_url parameter) or can be specified during job submission time with -jsv (client side jsv). With recent performance improvements when processing client side JSV scripts in UGE 8.1.7 it makes now sense to compare different scripting languages in which JSV scripts can be written.

With Sun Grid Engine or older Univa Grid Engine

HPC Lessons for the Wider Enterprise World

on Wed, 01/29/2014 - 15:38

Is HPC so specialized that the lessons learned from large-scale infrastructure (at all layers) are not transferrable to mirrored challenges in large-scale enterprise settings? Put another way, are the business-critical problems that companies tackle really so vastly different than the associated hardware and software issues that large supercomputing centers have already faced and in many areas, overcome?

Don't Drive Your Hybrid Car in 1st Gear

on Mon, 11/25/2013 - 16:27

Or how to REALLY save energy in your data center

Let's say you are concerned about your monthly spending at the fuel pump or about the exploitation of oil resources or about the environment. Heck, maybe you are worried about all of the above! Consequently you are looking into buying a fuel efficient car, possibly one with a hybrid engine or any other low fuel consumption engine. Would you then drive it in first gear all the time? And then mostly with full throttle to achieve at least some level of speed? Certainly not.

Technical Computing Environments During 20 Years of Evolution

on Fri, 06/28/2013 - 10:06

At Univa we are celebrating 20 years of Grid Engine starting from this month. So I thought this anniversary might make it worth to review how mainstream technical computing infrastructure has evolved over the past 20 years along with or, as we should we rather say, stirred by the Grid Engine technology.

The first use cases in 1993 for the Grid Engine technology (then called CODINE) was clustering of desktop and desk side workstations which engineers or scientists were using for their interactive work but which would get harnessed into a distributed computing system for throughput or parallel
