Thanks for reply. But I want to have an imagination about the behaviour of my server. Therefore I need an Code which I can run it on my server. Could anyone give me an example for any code? My last code was a simple example and not enough to get an imagination.
Thanx in advance List-Post: users@lists.open-mpi.org Date: Sun, 24 Jan 2016 10:21:07 -0500 From: esal...@gmail.com To: us...@open-mpi.org Subject: Re: [OMPI users] how to benchmark a server with openmpi? We've looked at performance in detail with regard to OpenMPI Java for large scale real data analytics. Here's a paper still in submission that identifies 5 rules you'd find useful to get good performance. It talks about how the number of processes affect performance as well. Tests were done up 3072 cores on a large Intel Haswell HPC cluster https://www.researchgate.net/publication/291695527_SPIDAL_Java_High_Performance_Data_Analytics_with_Java_and_MPI_on_Large_Multicore_HPC_Clusters Thank you,Saliya On Sun, Jan 24, 2016 at 9:41 AM, Nick Papior <nickpap...@gmail.com> wrote: *All* codes scale differently. So you should do these tests with your own code, and not a different code (such as MM). 2016-01-24 15:38 GMT+01:00 Ibrahim Ikhlawi <ibrahim_...@hotmail.com>: Hallo, I am working on a server and run java codes with OpenMPI. I want to know which number of process is the fastest to run my code with? For this reason I wrote a code that multiply two matrices but the differences between the results is not significant. Therefore I want to know how can I benchmark my server? Or is there any example which I can run many times on a different number of processes, so that I can see which number of process is the best? Or is there examples with results which I can compare with my results?
