CUDA 5.5 released

    imageA few days ago, CUDA 5.5 was released. Unfortunately, the main number of innovations and amenities concerns owners of video cards with Compute Capability 3.5.

    But there is something that will suit all users of the main Linux distributions - repositories have appeared!

    The full list can be found in Release Notes [ pdf ]. Under the cut, a list of what seemed to me the most interesting.


    • MPS (Multi-Process Service) allows several processes in an MPI program to transparently use the same GPU with Compute Capavility 3.5
    • Added support for ARMv7 (but not yet fully tested, see Release Notes)
    • Repositories (cheers!) For Ubuntu 12.04 / 12.10, OpenSUSE 12.2, SLES 11, Fedora 18, RHEL 6
    • Updated libraries CUFFT, CUPTI, CURAND, CUSPARSE, Thrust.
    • Under MacOS, Clang is used as a compiler
    • Debugging programs using cuda-gdb can now be done on one video card if its Compute Capavility 3.5 (previously it took two)
    • Remote debugging supported
    • Now you can debug MPI applications
    • Visual Profiler supports profiling programs with dynamic concurrency (those in which kernels from kernels are called)
    • All listed features about debugging, compilation and profiling are available in the updated Nsight Eclipse Edition


    At the moment, according to Wikipedia , CC 3.5 is on the Tesla K20X, Tesla K20, GeForce GTX TITAN and GTX 780 (all based on GK110). Tesla are intended solely for calculations (they do not have video outputs), the last two video cards are “gaming”.
