    Question installation needs license file

    When I try and do the installation using the gui interface, it asks for a license file. How do I get one?

    Unhappy GROMACS 4.6 does not compile

    Just tried to compile GROMACS with AVX-256 CPU acceleration, but the 02-11 nightly choked on our SIMD intrinsics kernels:

    Note that I was compiling current git GROMACS 4.6 (release-4-6 branch) with default configuration on a Sandy Bridge machine. Feel free to drop me a mail if you need help with compilation or testing.

    PS: And if I disable AVX and fall back to SSE4.1 the code compiles, but (mdrun) segv-s immediately after startup.

    I know it's quite and old thread, but what ever happened with github repositories? They seem to not have been touched in year or so, is EkoPath no longer open source?
