Re: [OMPI users] IO performance

Rob Thanks, these are the kind of suggestions I was looking for. I will try them. But I will have to twist some arms to get the 1.5 upgrade. I might just install a private copy for my tests. T. Rosmond On Mon, 2012-02-06 at 10:21 -0600, Rob Latham wrote: > On Fri, Feb 03, 2012 at 10:46:21AM

[OMPI users] IO performance

Recently the organization I work for bought a modest sized Linux cluster for running large atmospheric data assimilation systems. In my experience a glaring problem with systems of this kind is poor IO performance. Typically they have 2 types of network: 1) A high speed, low latency, e.g.
