DanT's Grid BlogIt's hip to be square!Job Scheduling With Grid Engine- November 30, 2007 Grid Engine is a Distributed Resource Manager (DRM). It's job is to match workload to resources in the most optimal fashion possible, otherwise known as scheduling jobs. What Grid Engine doesn't do is provide an automated means to run certain jobs at certain times of the day. For example, I have an application that I want started at 8:00 and stopped at 17:00, and I want that to happen every weekday of the year. You could certainly use Grid Engine to find a home for the application instance..http://blogs.sun.com/templedf/entry/job_scheduling_with_grid_engine DRMAA For Platform's LSF- November 28, 2007 In case you didn't notice, the Distributed Resource Management Application API (DRMAA) has become one of the first two official recommendations from the Open Grid Forum. Along with this long awaited official recommendation status came an exciting surprise: Platform now has a DRMAA implementation for their LSF product! The implementation comes courtesy of the FedStage Developer Network. FedStage has only produced a C binding for LSF so far (and I'm told that's all that's planned), but since...http://blogs.sun.com/templedf/entry/drmaa_for_platform_s_lsf Announcing Grid Engine 6.1 Update 3- November 28, 2007 Grid Engine 6.1 update 3 is now ready for download!

(Thanks, Rayson!) If you're interested in what it's like to install a half-million-dollar data center in a box, definitely check it out!http://blogs.sun.com/templedf/entry/thinking_inside_the_box The Grid Engine Scheduler Quantified- November 9, 2007 Earlier this week I helped out with an RFP that included a section for Sun Grid Engine. After I sent in my contributions, it occurred to me that some of the information might be useful to others. Below is my description of the Grid Engine scheduler. It gives a pretty thorough idea of what the scheduler is capable of. In case you were wondering. Sun Grid Engine supports mixed workloads of batch, interactive, parallel and parametric jobs. The Sun Grid Engine scheduler is a highly...http://blogs.sun.com/templedf/entry/the_grid_engine_scheduler_quantified Sun Grid Engine Workshop 2007 Proceedings- November 3, 2007 This news is a bit old by now, but better late than never. The proceedings from the Sun Grid Engine Workshop '07 are now online. We've posted a summary of the meeting and the presentations in PDF format. I was really impressed by the quality and the usefulness of the presentations this year. If you couldn't make it to Germany in person, definitely check out the slides online.http://blogs.sun.com/templedf/entry/sun_grid_engine_workshop_20071 Code Freeze for 6.1u3- November 3, 2007 The code freeze for the 6.1u3 release has now happened, so if you want to checkout the V61_BRANCH and give it a whirl, please do. (You'll have to compile it yourself, of course.) If you discover any issues, please email them to the devgridengine.sunsource.net mailing list.http://blogs.sun.com/templedf/entry/code_freeze_for_6_1u3 Announcing Grid Engine 6.1 Advance Reservation Snapshot 3- November 3, 2007 The latest version of the 6.1 Advance Reservation snapshot is now available for download. Snapshot 3 has had the u2 changes merged in, plus it includes some new features from the maintrunk: some scheduler improvements, some protocol optimizations, and a new flatfile spooling parser. Because of the new flatfile spooling parser, upgrading from a previous 6.1 or 6.1AR release using flatfile spooling will be a little trickier than usual. The reason for the new flatfile spooling parser is to...http://blogs.sun.com/templedf/entry/announcing_grid_engine_6_1 |
