Problems with running in parallel

Miguel_M_Valero · December 8, 2021, 14:20

Hello!

I have just installed OpenFOAM8 in my workstation, by following the steps indicated in the official website. However, when I try to perform a computation in parallel I obtain the following error after typing this: $ mpirun -np 4 pimpleFoam -parallel | tee log

--> FOAM FATAL ERROR:

Could any of you give me any tips about what is going on? I'm quite new with OpenFOAM, but the error has nothing to do with the solvers (I can run a simulation with only one processor in all the solvers) and, definitively, I know how to use the file decomposePardict. Maybe a problem with the installation somewhere?

Thank you so much in advance!

Hello,

I know nothing about openfoam. It sounds like a problem in mpi environment variables. Do you have various MPI installed on your system ? Like openmpi + mpich ? Does the mpirun used to launch your program match the MPI version used to compile the code ?

Simbelmynë · December 9, 2021, 08:15

Have you decomposed the problem into parts (4 in your case) or do you just try to run it in parallel directly?

I have realized that the mpirun that I was employing to launch the program was 3.3.2 and the MPI version is 4.0.3. Thank you so much for your reply!

I have the same error message and after checking ( mpirun --version) returned 3.3.2 as well. How do I check my MPI version to compare it with and how do I resolve this issue?

‘ompi_info‘ command can help you.

For me the solution was really pragmatic. As I run my computation on a small server, we created a new ubuntu install with only openFoam on it.

With the clean ubuntu (22.04 LTS) and by just following the openFoam install guide exactly step for step, https://openfoam.org/download/9-ubuntu/. Now it runs perfectly.

I do not know if this solution works for your situation, but it is a quite simple one.

With kind regards,
Jelle

Please see the FAQ page for debugging suggestions Could any of you give me any tips about what is going on? I'm quite new with OpenFOAM, but the error has nothing to do with the solvers (I can run a simulation with only one processor in all the solvers) and, definitively, I know how to use the file decomposePardict. Maybe a problem with the installation somewhere? Thank you so much in advance!

The next step is to download Selenium. ... Step 3: Eclipse Installation. To install the Eclipse IDE, go to the following link and download the eclipse tool. ... Step 4: TestNG Installation. ... Step 5: Parallel Execution of Test Scripts. more info about original and imported products here : https://barusgolden.com/

naffrancois Senior Member Join Date: Oct 2011 Posts: 242 Rep Power: 17	Hello, I know nothing about openfoam. It sounds like a problem in mpi environment variables. Do you have various MPI installed on your system ? Like openmpi + mpich ? Does the mpirun used to launch your program match the MPI version used to compile the code ? Miguel_M_Valero likes this.

Jelle Lagerweij New Member Jelle Lagerweij Join Date: Jul 2022 Posts: 21 Rep Power: 4	For me the solution was really pragmatic. As I run my computation on a small server, we created a new ubuntu install with only openFoam on it. With the clean ubuntu (22.04 LTS) and by just following the openFoam install guide exactly step for step, https://openfoam.org/download/9-ubuntu/. Now it runs perfectly. I do not know if this solution works for your situation, but it is a quite simple one. With kind regards, Jelle
