[OMPI users] OMPI core/thread scaling

Hello, Is there any information or data available on OMPI core/thread scaling ? What benchmark would you suggest for the same ? To have both Intra-Node and Inter-Node information would be great. Please let me know. Thanks, - Sreenidhi.

[OMPI users] Error for openmpi-dev-3868-g178c97b with Solaris

Hi, I tried to build openmpi-dev-3868-g178c97b on my machines (Solaris 10 Sparc, Solaris 10 x86_64, and openSUSE Linux 12.1 x86_64) with gcc-5.2.0 and Sun C 5.13. I was successful on my Linux machine, but I got the following errors on both Solaris platforms with both compilers. tyr openmpi-dev-

[OMPI users] OpenSHMEM - Undesired Result !!

While executing the code in the file exp4.c (Attached) we faced undesired result. This code allows all PEs to add a 'quantum' value to a variable on a particular host. But in some cases few of these 'quantum' values are lost. I have attached the file and a screenshot of the output. In the scree

Re: [OMPI users] OpenSHMEM - Undesired Result !!

Ryan, what if you uncomment the barrier before printf ? I can see a scenario in which printf is invoked on rank 0 before all shmem_long_add have started/completed on rank 1 Cheers, Gilles On Wednesday, April 20, 2016, RYAN RAY wrote: > While executing the code in the file *exp4.c* (Attached)

Re: [OMPI users] OpenSHMEM - Undesired Result !!

Ryan, What you witness in your execution is that your execution over 2 processes drifted by 49 iterations. Because your example avoid any synchronization call, your processes are not synchronized and therefore any output (in increment of quatum) is correct. As Gilles suggested, enabling the shmem_

Could you please rerun these test and add “-mca pmix_base_verbose 10 -mca pmix_server_verbose 5” to your cmd line? I need to see why the pmix components failed. Thanks Ralph > On Apr 20, 2016, at 10:12 AM, Siegmar Gross > wrote: > > Hi, > > I have built openmpi-v2.x-dev-1280-gc110ae8 on my
