That sounds something like Condor, if you had a homogenous network. Without it, you need a grid; but the application programmer will have to split stuff up into bite-sized chunks (like SETI@home) and provide binaries for each possible host in the grid.

[SLUG] OpenMosix vs Grid engine
Hi all, Anyone know what is the difference between Open Mosix clustering vs the Grid Engine project http://gridengine.sunsource.net/ as far as the end user's application software is concerned?

[SLUG] OpenMosix vs Grid engine
Jill == Jill Rowling Rowling writes: Jill Hi all, Anyone know what is the difference between Open Mosix Jill clustering vs the Grid Engine project Jill http://gridengine.sunsource.net/ as far as the end user's Jill application software is concerned? It's my understanding (which could be quite wrong) that a computing grid is a much larger thing than a cluster multiple clusters can participate in a grid; and a grid can be heterogenous. When you're writing code for a cluster, you use OpenMPI or something. I don't think that MPI will work over a grid --- a grid is more a way to distribute jobs to clusters or machines within the grid (like NQS but bigger). See http://www.gridcomputing.com for more details. However, this leads to another question: Does the Grid Engine implement a cluster or a grid? SETI@home is an example of a grid computation.

quote who=Rowling, Jill Anyone know what is the difference between Open Mosix clustering vs the Grid Engine project http://gridengine.sunsource.net/ as far as the end user's application software is concerned? It's essentially the difference between 'single-image clustering' and 'multiple-image' (or even heterogeneous) clustering. With OpenMosix, everything is handled at the kernel level, allowing you to run and migrate any process [1] within the cluster. There are no special tools to run process on the cluster, because you're already a member of it (though there are utilities to say 'run this process on that node', etc). The Grid Computing stuff that Sun ships, from what I've worked out, is not as cool. :-) You must run processes with the q* utilities, it works with jobs and queues, handles multiple architectures, etc. So, OpenMosix acts like a big fat SMP box that you can just keep adding processors to (which prefers processes to threads), whereas Sun's Grid computing stuff is basically just a job/queue-driven processing farm with the ability to grok multiple archs as part of the cluster.

RE: [SLUG] OpenMosix vs Grid engine
Hi Jeff, Thanks for that. What I'm trying to do is speed up some programs we use at work. Some of them take a week to run on a PC (er, maths and statistics...:) and there are a number of machines around the place that are idle at night. I was looking for something maybe not as inefficient as SETI@home that could be run on a variety of OSs: Linux, IRIX, Solaris, WinNT preferably without too much pain but preferably controlled from one node (ie the programmer's work area). It's important that the job run at low priority because the various machines have other tasks that must be done at certain times, and this application is supposed to only run when the machine is otherwise idle.
