Description Coarray Fofrtran (CAF) is a parallel programming extension of the Fortran syntax that allows a programmer to view a single shared partitioned address space. CAF is supported by Cray and Intel compilers on Edison. Using CAF with Cray Compilers How to compile Edison default programming environment is Intel, so you need to swap to Cray programming environment by issuing the following module command: % module swap PrgEnv-intel PrgEnv-cray Then compile the CAF codes with the fortran… Read More »
Alva, named after Thomas Alva Edison, is the test and development system for Edison. All changes and upgrades to Edison hardware, firmware, and software are tested on Alva first before being applied to Edison. At a high level, you can consider Alva as a small Edison, and can expect Alva to have a similar environment setting as Edison. If you are granted access to Alva, you can compile and run jobs as you would on Edison. However, as hinted by the purpose of this system, Alva and its environment… Read More »
