MPI_Finalize error
Hi everyone
I am runing my priject in fluent 15 After about 4000_700 iteration my run is stoped and writed this eror : MPI application rank 0 exited before MPI_FINALIZE() with status I dont know why I get this eror and what I do??? Please help me |
1) "with status.." what status? Did your give us a full error text?
2) Maybe, you are out of memory - then, operation system kills the process (this is specifically true under Linux) 3) It could be internal calculation error. Does single-thread FLUENT solves the problem correctly? You could autosave your calculation every N (e.g., 300) iterations, then, after fail restart from the last saved file. 4) if your parallel FLUENT fails every time independently of the task being solved (with different problems/case-files), it could be defective memory card |
