Parallel computation issue with restart simulation

Hi, I am using the coupling between Saturne and Syrthès which works fine. When I use parallel computation and try to restart a new simulation from a previous one, I get an error linked to the .res file from the first simulation (It is not the case when I use simple computation). Indeed, it says that...

Re: Multi process issue during coupling

Hello, As you suspected, it was a problem of MPI libraries that were different. I did re-installed Syrthès with the same MPI libraries than Saturne and now the run_solver.log file does appear in the RESU_COUPLING directory when I launch a computation. But I still have a problem, the computation stil...

Re: Multi process issue during coupling

Hello, Since I've installed Code Saturne with the semi-automatic installation script, I did not specified what was the path to MPI libraries (I let the default options) while during the installation of Syrthès, I had to specify it in the setup file. How can I check which MPI libraries are used by Sa...

Re: Multi process issue during coupling

Hello,

I did found a run_solver file but I don't know if it is the one you were talking about (see joined file).
The listing file for the solid domain is empty.

Best regards,

Multi process issue during coupling

Hi, I am working on a cluster with SLURM as batch system. I am computing the coupling between Code Saturne and Syrthès from the tutorial 'Three 2D disks' on CS website. I did compute the tutorial for both separately first but when I'm trying to perform the coupling, I've got an error message related...

Cannot find syrthes home directory when working on a cluster

Hello, Working on a cluster, I'm trying to launch Syrthès simulations. Every time I run the simulation, I get directly the following error (note that I was just creating a coupled case here but I get the same error when I run only Syrthès) : code_saturne create -s 3_2D_DISKS -c FLUID --syrthes SOLID...

Re: Stop to avoid exceeding time allocation on cluster system

Hello, So during the last few days, I tried to add the "return;" at the beginning of the armtps and then launch "./configure" but an error occured due to this "return;". So I came back to the add a "return;" at the beginning of the "cs_resource_get_max_ti...

Re: Stop to avoid exceeding time allocation on cluster system

Hello, I did run "make install" after writing the return; at the beginning of the cs_resource_get_max_timestep function in the cs_resource.c file but the simulation still stops at 45 minutes. I even relaunch "./configure" followed by "make" and "make install" ...

Re: Stop to avoid exceeding time allocation on cluster system

Hello, The squeue -h -j $SLURM_JOBID -o %L returned the same output as before : CLUSTER: lemaitre3 9:49:59 I tried adding a "return" at the beginning of the cs_resource_get_max_timestep but it changed nothing. The simulation is still running until 45 minutes before being shut down. Maybe a...

Re: Stop to avoid exceeding time allocation on cluster system

Hello, I did set "batch = SLURM" in the code_saturne.cfg file. Then, I've created a new case and updated the runcase script with specifications of my simulation. Finally I ran the command "sbatch runcase". First, I ran with the original parse_wall_time_slurm but the error came ba...
