Hello, Until now I've managed to provide native compilation support. The flags are passed correctly and the modules generated separately from the rest.
However, while I was working on this I realized that most of the scientific software needs workarounds and hacks to be compiled for the Xeon Phi. The most common (and less problematic) is adding the "--host=x86-k1om-linux" option when compiling with configure/make, this one is pretty simple. In other cases (and not only one or two, I'm afraid) cross-compilation is not supported by the program, or needs strange hacks that are incredibly hard to automatize. In the end, this leaves only a few programs that can be compiled just with the native support without expending some time with the particular details of each app. So my question is: is this worth a PR? It's interesting having this option knowing that most of the compilations for the Phi will need extra work? I'm asking this because I don't think I can call it "Xeon Phi support" knowing that only half the work is done. While the common part of the Phi builds is included, it will require for developers to create specific easyconfigs in every application desired. 2016-05-19 13:21 GMT+02:00 Adrian Rodriguez Vilas < [email protected]>: > My first idea is to get a toolchain compiling for native execution, as we > also have few use for them as accelerators.
