Hi, Does anyone know of a simple, open, batch queuing package for Linux? Something more featured than at and cron, but not so complex as the clustering solutions? Some background - I am porting an application from UNIX to Linux (which is scary because I am an expert in neither, but somehow the UNIX application has been going for about 8 years now). I investigated various UNIX batch queuing packages at the time, and found that most were very out of date and no longer actively supported. People had moved on to clustering approaches, and the old, simple solutions were left behind. So I wrapped *at* with a kludgy mechanism to get what I wanted - a means of controlling the order and number of executing jobs. Now I find the Linux *at* to be lacking some of the UNIX's features, such as no accompanying queuedefs file that limits the number of simultaneously executing jobs, and the termination of job status on running jobs after one hour. (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=150667) I could wrap this again, but before doing that, I'm wondering if anyone else has found a simple batch queuing package for Linux. I've looked at various alternatives, such as: GNU Queue http://savannah.gnu.org/projects/gnu-queue/ Being rewritten, not available for download More of a load balancer Generic NQS http://www.gnqs.org/ Not maintained for 6 years. Portable Batch System http://www.openpbs.org/ Unsupported, old, unfriendly keepers You get the picture! Funnily enough, there IS a standard for a simple UNIX/Linux batch system. It's called "Batch Environment Services" and it's part of the Open Group/IEEE Single Unix Specification. To view it: http://www.opengroup.org/onlinepubs/009695399/ Select a volume: Shell and utilities Shell and utilities: 3. Batch environment services It has all of the needed commands: qalter qdel qhold qstat qsub, etc. But it's optional - you can be certified as compliant without implementing Batch Environment Services, and to the best of my knowledge, no one has. I guess there's just no demand for it. Any comments appreciated. Thank you! Geoff Gigg
