HFSS and MPI for use of solver domain (intel MPI or platform MPI)

Hello everyone

First i have to provide this information:

1- i have instaled the latest version of Intel MPI and platform MPI of IBM.

2- i have to use one of them through Ansys HFSS 15 x64 which is a EM-software in a GigE network.

3- HFSS dont have any problem with discrit processes (for ex. 15 paralel process in optimetric solution will share trough 3 computer on network correctly)

4- i need to use memory of other computers on the network, so need distribute the RAM usage with enabling "use of solver domain"

5- the error i got every time is "authentication faild" or "unable to create child process in hosts" (see the below)

6- the ansoft RSM on all machins are running and the testing tool on hfss work properly.

now i need help to configure Intel MPI or platform MPI in order to split the matrixes.

i will apreciate that anyone can help me.

with the special regards

Hi hassan_k,

I am getting exactly the same error when I am trying to use Domain decomposition method. It works perfectly fine when I use it with just one node,i.e., 16cores and 32GB RAM (all memory shared between 16 cores). If I try to distribute the task over multiple nodes, I get the same error as yours.

Please let me know if you have managed to solved this problem.

Thanks,
