Re: [OMPI users] Hyper-thread architecture effect on MPI jobs

Saygin, You can use mpstat tool to see the load on each core at runtime. Do you know exactly which particular calls are taking longer time ? You can run just those two computations (one at a time) on a different machine and check if the other machines have similar or lesser computation time. -

[OMPI users] MPIError:MPI_Recv: MPI_ERR_TRUNCATE:

Hi All, I have written a program where MPI master sends and receives large amount of data i.e sending from 1KB to 1MB of data. The amount of data to be sent with each call is different The program runs well when running with 5 slaves, but when i try to run the same program with 9 slaves,
