Thread: Kerrighed

Hey there!

I've tried to set up a kerrighed cluster, because it looks like a single SMP maschine..

I've just tried to do this!
Does anyone know something similar? In favor: easy to install and easy to use?

I am only used to program microcontrollers, so i don't know much about setting up a cluster or how to program proggs for parallel use!

Hi,

kerrighed, openssi, bproc etc projects all try to emulate a single system image on a cluster.

It really depends on what you want to do in your HPC work.

In general, such emulations brings with it over heads which slows down your parallel codes (but it does makes cluster management way-much easier!)

If you program in MPI (openmpi, mpich) you would be generally better off assembling a traditional cluster with a tool such as Kusu. If you program in OpenMP, then an alternative would be INTEL's Cluster OpenMP.


cheers!

Hi,

The main "problem" I can see with Kerrighed, is the "experimental only" support for x86_64, as mentioned here:

Status - Kerrighed

Support for 64 bits machines (EXPERIMENTAL)

From the same page, "Stable 64 bits support" should be available in the next release (Roadmap section) which was supposed to be available in June 2008.
