sbstndb / fortran_affinity

Description

Here is a simple exemple in how to impose a process affinity in fortran.

• Interface C and Fortran codes thanks to iso_c_bindings
• Call schedule affinity functions from POSIX compliant sched.h header

Then, we can entirely choose the affinity of the process. This is essential for High Performance executions for :

• avoid context switching
• better thread/process hybrid execution. For instance, we often need to set each process in an unique NUMA nodes and spread threads in the corresponding NUMA node.

Compilation

cd src
. make.sh

Execution

./main
