Dear Thomas,
gfortran:
gfortran-7 support by FLUKA is expected to be dropped soon, as gfortran-9 has just been released, and FLUKA usually only supports the two latest releases.
gfortran-8 version should be available until gfortran-10 is released sometime in 2020.
You can compile gfortran from the source without admin rights (if the necessary tools are already installed). For more details see:
https://wiki.osdev.org/Building_GCC
Docker:
The docker version of FLUKA is NOT suitable for clusters, as it requires admin rights to run. It is only intended for single user PCs.
g77:
The g77 version of FLUKA should be available in the long term.
Please note, depending on the OS of the cluster g77 may not be available.
There shouldn't be any meaningful difference in the results between the g77 and gfortran versions, but the gfortran one has an ~25-30% performance advantage.
I hope this helps.
Kind regards,

Subject: [fluka-discuss]: Code version preference for cluster use
Dear all,
I am using a 64-bit linux cluster to run my simulations and the administrators are reluctant to install newer versions of gfortran to support the new fluka distributions. They were kind enough to do this once for gfortran 6.4 but now I have to ask for a fresher installation.
Should I ask for a g77 since all distributions have a version with g77 compilation or should I ask for a gfortran-7, gfortran-8, docker?
What would be the difference in the simulation results/efficiency with these versions?
The point is to not have to ask for a 3rd time with the next fluka distributions.
Best regards,
Thomas
