Re: [OMPI devel] Large IMB test problems?

Ralph, On our quest for better shared memory collective, we did some runs with 16 cores Intel machines. The SM worked as expected, as far as I can tell. Unfortunately we only have one such node, so we never tried more than 16 processes. george. On Jul 24, 2008, at 11:13 PM, Ralph

[OMPI devel] Large IMB test problems?

2008-07-24 Thread Ralph Castain
Yo folks We are trying to run some tests on a new cluster and are having a problem telling hardware, system software, and OMPI failures apart. This is a 16-ppn Opteron system running SLURM under RHEL (forget the precise version), with IB and OMPI 1.2.6. Everything launches just fine and

Terry, I did not and I will not enforce any policy at this point. I'm confident developers in this community can take such decisions by themselves, without restrictions from the RM. As a hint, the most basic common sense (make sure it compile and it really solve the problem it is

It might be worthwhile to spell out the conditions of when someone should let changes soak or not. Considering your changeset 19011 was putback without much soak time. I am not saying 19011 needed more soak time just that I think it adds potential confusion as to what one really needs to do

I tend to agree with Brian's comments, I would like to see this pushed into the 1.3 branch asap. However, I'm concerned with the impact on the code base of the required modifications as described on the TRAC ticket and on the email thread. I wonder if we cannot use the same technique that
