OpenFOAM on HPC
Hello,
I'm new in HPC: after "module load OF", running "blockMesh -help" gives "cmd not found" does someone, who's experiences in HPC, know what's wrong and why? thank you in advance Philip |
It's possible, that you have to activate the module before being able to use it.
After module load... try "foamInit" or "source $FOAM_INIT" these were the commands necessary on the HPC I used to work with. |
hello, Swirl,
thank you very much for the reply. btw. I want to check with you: if possible, to compile/install other 3rd party package under the HPC-pre-installed OF-environment? if yes, how? thank you in advance |
Do you mean software like custom solvers or models? You should be able to compile those normally, like you would on any other PC, given the admins haven't blocked it. You could potentially also use the <nameOfApplication>.so file that was created from compiling the custom code on another machine and save it to either the $FOAM_USER_APPBIN (for solvers) or $FOAM_USER_LIBBIN (other types of custom software) directories on the HPC filesystem. This however only works, if the machine the program was compiled on has a similar CPU architecture than the HPC. Not sure if this is what you meant however.

hello, Swirl,
many thanks for the reply and you're right, the custom solver based on OF. Actually now I can load, thus use OF in hpc, so i get 2 further options: - one alternative is after loading OF in hpc, compile the custom solver directly - or first install OF (again) in my hpc-account, then compile the custom solver based on the newly installed OF not sure yet, which one works out anyway, thank you for the hints |
btw. I just start using hpc, i.e. no experiences yet, so
could someone give some ref., info, advices regarding the node-, core-,and memory-allocation based on a simulation task? thank you in advance |
what's the output of command "module load OF"? Is it succeed?
have you ever list all the modules available? |
hello, bestucan,
many thanx for the reply. yes, the "load module" worked out.... when I get time you'll tell you more. now I'm busy with studying the "node, core allocation" ..... it would be great if you or someone could share me some hints thank you again and wish you a great 2023 |
Hello All,
I am trying to run a case on HPC. The setup sometimes run and sometime shows an error as Code:
[1672747228.750479] [cn098:39424:0] mm_posix.c:207 UCX ERROR open(file_name=/proc/39378/fd/25 flags=0x0) failed: No such file or directory I have tested both shared memory option as yes and no in decomposePar dict. How can I solve this issue? Pardon me if I am missing any detail to give as I don't know what else is playing a role here. Any more information is required please let me know. Regards krishna |
