Distributed computing

Eileen Millen_1 — Tue, 22 May 2001 15:07:25 GMT

I need some sort of load-balancing software for processors and memory.

We have 8 multi-CPU machines running HP-UX 10.20, and a bunch of users with Fortran programs. Everything is NFS-mounted from one location. Is there anything available that will let users submit Fortran programs to run "somewhere" without worrying about which system is free?

thanks in advance

Here's one thought,

Have you checked out PRM (Process Resource Management) software from HP. I believe you use this to reserve a % of process resources...maybe you could then setup your Fortran programmers into a specific group and then only allow this group to have access to % of a system.

Like I said, just a thought,

Hi Eileen,

Your question made me think a bit and I did come up with one promising approach. I don't claim that it's finished but still it should work. The idea is to run a series of sar -u commands on remote hosts via remsh and to look for the most idle system. You would then execute the FORTRAN code as a remsh on the remote host. I do assume that these are non-interactive programs. If not, the problem becomes more difficult. Nevertheless the germ of the idea is in the attached script.

Food for thought, Clay
