DanT's Grid BlogIt's hip to be square!Sun Cluster Core Is Now Open Source!- May 29, 2008 The Solaris Cluster team today contributed over 2 million lines of source code to the open source community, completing the promise we made almost one year ago to open source the complete Solaris Cluster product under the name, Open High Availability Cluster. Listen to a podcast with Meenakshi Kaul-Basu, Director of Availability Products or read the official press release. Solaris Cluster is Sun's High Availability Cluster offering. The product community hosts a blog and wiki where you can...http://blogs.sun.com/templedf/entry/sun_cluster_core_is_now Making Grid Engine HA with Open High Availability Cluster and OpenSolaris- May 27, 2008 At the Open Source Grid & Cluster Conference a couple of weeks ago, Ashu from the Solaris Cluster team gave a 30-minute presentation about building a highly available Grid Engine cluster using the Open HA Cluster project. (Open HA Cluster is the open-sourced Solaris Cluster.) If you've got a spare 30 minutes, it's worth a look.http://blogs.sun.com/templedf/entry/making_grid_engine_ha_with Intro to Grid Engine Queues- May 27, 2008 I just posted this information as answer to a question on the Grid Engine users mailing list, but I thought it was useful enough to post here, too. If you're new to Grid Engine and trying to understand what a queue is, hopefully this explanation will help. Let's take it from the top. A queue is where a job runs, not where it waits to run. When a job is in the qw (queued and waiting) state, it has not yet been assigned to a queue. A job that has been assigned to a queue is in the r...http://blogs.sun.com/templedf/entry/intro_to_grid_engine_queues ZFSUSB Magic- May 27, 2008 Even if you can't speak German, this is a really cool video: The basic gist is that Constantin and crew think the Thumper is a really cool machine, but that at $50k, it's a bit expensive for a developer to have under his desk. As an alternative, they propose a stack of inexpensive storage, in this case, a jumble of USB sticks. Using ZFS, Constantin pools together the sticks in RAID groups of three as one big storage pool. To demonstrate ZFS's recovery features, he copies a video onto the..http://blogs.sun.com/templedf/entry/zfs_usb_magic Kumba-HPC-ya- May 27, 2008 There's a new effort afoot in the OpenSolaris world to build a community around using OpenSolaris (and Solaris) in high performance computing. If you're interested in HPC on OpenSolaris, head over to the OpenSolaris HPC Community and have a look-see. As a product of the community, the HPC Stack project is attempting to define what software would be needed to build a complete and useful HPC software stack for OpenSolaris. Right now, the main discussion for the HPC stack project is actually...http://blogs.sun.com/templedf/entry/kumba_hpc_ya DRMAA JavaScript Binding- May 27, 2008 Thanks to Richard's clever work, we can now say that DRMAA works from JavaScript as well. Much coolness! (By the way, welcome to the blogosphere, Richard!)http://blogs.sun.com/templedf/entry/drmaa_javascript_binding Death By Powerpoint- May 27, 2008 If you haven't seen this presentation yet, it's worth a look. It's a really nice overview of how to create an interesting and compelling presentation. Of course, having something useful to say also helps.http://blogs.sun.com/templedf/entry/death_by_powerpoint Grid Engine 6.2 Beta- May 27, 2008 In case you didn't notice, Grid Engine 6.2 is now in beta. Download a copy and give it a whirl! (By the way, I think there's a issue with the installer on Solaris, but I haven't confirmed it. Let me know if you have any trouble.)http://blogs.sun.com/templedf/entry/grid_engine_6_2_beta One More Down, Two To Go- May 26, 2008 This news is a little old now, but it's no less worthy of announcing. Thanks to our friends at FedStage, the same folks who brought us the Platform LSF DRMAA implementation, there is now an implementation of DRMAA for Altair's PBS Pro! With the addition of PBS Pro to the DRMAA family, that now leaves just two major DRMs without DRMAA support: DataSynapse GridServer and Microsoft CCS. Sun Grid Engine, Platform LSF, and Altair PBS Pro all have DRMAA implementations. Condor, Torque, EEGE,...http://blogs.sun.com/templedf/entry/one_more_down_two_to Exclusive Host Access With Grid Engine- May 23, 2008 I just got the following request in email: It just happens that I'm using PBSpro ... at the moment... You can have this resource request... PBS -l nodes=101:ppn=8excl We can implement the nodesppn with PEs in SGE. But excl means exclusive access to a node (only applies to batch). That is what I want from SGE. Since this is a request I've heard before, I thought it might be useful to share my answer. Imagine you have a grid of n machines, and each machine has the same...http://blogs.sun.com/templedf/entry/exclusive_host_access_with_grid |
