Can code-saturne run on ARM-based servers?

We need to run CODE_SATURNE on an ARM-based server. Do we need to modify CODE_SATURNE source code? If so, where do we need to modify it?

Hello,
This post should be in "installation", not "general usage".
In theory the code is portable, and all architecture-specific code is encapsulated in conditionally compiled sections, so yous should not need to modify the code. What compiler are you expecting to use ? Which code version ?
Regards,
Yvan

Sorry, thank you for your reminder, I am using this forum for the first time, and if I post later, I will classify it correctly.
I have no idea yet about the compiler and the code version used. Do you have any suggestions for how I want my code to run on an ARM-baesd server?
Regards.

Hello,
No, I do not have any specific recommendations. I would start with the classics like gcc, possibly trying another compiler if the vendor recommends something specif.
Regarding MPI, is your machine a cluster (in which case there is probably at least one recommended MPI library), or a simple server (in whic case either MPICH or Open MPI will do fine) ?
