Hi all, I just recently installed the Intel Fortran compiler on Fedora, I wanted to know: 1. How do I check if it’s installed correctly ? 2. How do I compile programs with ifort (I looked at intel’s website, it’s not really clear) 3. Does ifort have a coarrays option ? How do I use it ? 4. Is there a full manual of ifort ? Note: I installed using the offline installers from the intel website Thanks ---

2 & 3) This is an example ([https://github.com/vmagnin/exploring\_coarrays](https://github.com/vmagnin/exploring_coarrays)): ```auto $ export FOR_COARRAY_NUM_IMAGES=2 $ ifort -O3 -coarray m_xoroshiro128plus.f90 pi_monte_carlo_coarrays.f90 $ ./a.out ``` ---

I guess in Fedora it is installed similar to all Linuxes, in /opt/intel/… hierarchy. To use it, you have to set configuration of your shell (paths etc.). For `bash`, use `source /opt/intel/oneapi/setvars.sh` or (shorter, with a dot) `. /opt/intel/oneapi/setvars.sh` ---
