Hi All, I'm facing a strange problem with OpenMPI.
I'm developing an application which is required to send a message from each client (1 MB each) to a server node for around 10 times per second (it's a distributed render application and I'm trying to reach a higher frame rate ). The problem is that OpenMPI crash in that case and only works if I partition this messages into a set of 20 k sub-messages with a sleep between each one of them for around 1 to 10 ms!! This solution is very expensive in term of time needed to send the data. Is there any other solutions? The error i got now is: Signal: Segmentation fault (11) Signal code: Address not mapped (1) Failing at address: xxxxxxxxxxxxx The OS is Linux CentOS. I'm using the latest version of OpenMPI. I appreciate any help regarding that. Regards, Amr
