question regarding changing souce code

Hi, I'm trying to change a little part of the source code so that it might be possible to run with CPU+GPU. I'm wondering if if want to change the function _compute_cocgb_rhsb_lsq which is wrote in file src/alge/cs_gradient.c , do I need to change the file itself and recompile the whole software? or...

Re: Question regarding openmp usage

Hello, When compiling with OpenMP support (the default for code_saturne), when the compiler encounters an OpenMP section, it "outlines" the contained code, and generates a function matching that section, using names such as the ones you observed. Then, when running, it will run that funct...

Re: Problem rearding submitting job to cluster

Hello, I'll check the code. We have never encountered this issue, but I wonder whether it might be due to latency/delays in the filesystem operation leading to a directory not being empty yet. Not sure, just guessing, but I'll see if I can make the code more robust there. In the meantime, as a work...

Re: Problem rearding submitting job to cluster

Hello, This might be due some limited or restricted features on your filesystem, but has not been observed on another machine to my knowledge. Could you provide details on your system and build ? Regards, Yvan I just found that the compute node does not have command rmdir . It works fine now. Best ...

Re: Problem rearding submitting job to cluster

Hi, I am using gcc version 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC), I believe the compute node has the same setup. I built Code saturne 7.1.1 with this configure command: ./configure --prefix=/home/software/code_saturne2/install-parallel CC=mpicc CXX=mpicxx FC=mpifort F9X=mpifort AR=sw9ar NM=swnm RA...

Hi, I am trying to use code saturne on my working HPC ,and its login nodes and compute nodes are using different cpu setup, so I used the cross compile option during the installation. The installation was fine, but realize that when code_saturne was executed ,it will first run the python scripts and...
