If you compile software on an expensive supercomputer, it’s a good idea to select the languages and compilers with particular care. We report on tried-and-proved tools used on Super ... , built by IBM at a cost of around EUR135 million, has 19 compute islands with approximately 8,200 cores each, and six newer islands with 14,300 cores each.
