The Fortran 2018 standard defines syntax and semantics to allow a parallel application to recover from failed images (processes) during execution. This poster presents work to extend the GFortran compiler front end and OpenCoarrays library to support fault tolerant teams of images, enabling use of collective routines after an image failure.
