VS2022 Support: CUDA 11.6 officially supports the latest VS2022 as host compiler.Large CPU page support for UVM managed memory.Added L2 cache control descriptors for atomics.Added new NVML public APIs for querying functionality under Wayland.Added ability to disable NULL kernel graph node launches.The host-side compiler must support the _int128 type to use this feature. Full release of 128-bit integer (_int128) data type including compiler and developer tools support.A corresponding API, cudaGraphNodeGetEnabled(), allows querying the enabled state of a node. Support is limited to kernel nodes in this release. Added a new API, cudaGraphNodeSetEnabled(), to allow disabling nodes in an instantiated graph.Parallel Nsight 2.0 now available for Windows developers with new debugging and profiling features.GPU binary disassembler for Fermi architecture (cuobjdump).C++ debugging in CUDA-GDB for Linux and MacOS.Automated Performance Analysis in Visual Profiler.GPUDirect v2.0 support for Peer-to-Peer Communication.Layered Textures for working with same size/format textures at larger sizes and higher performance.Nvidia Performance Primitives (NPP) library for image/video processing.Thrust library of templated performance primitives such as sort, reduce, etc.C++ new/delete and support for virtual functions.No-copy pinning of system memory, a faster alternative to cudaMallocHost().Use all GPUs in the system concurrently from a single host thread.At the weekend I will probably run a 7.5 double check but current performance is a disappointment. Maybe I did something wrong but I don't think so. I'd be very interested in independent compiles and checks. > CUDA 7.5 seems to be at this run ~8% SLOWER than CUDA 6.5 but has a ~30% smaller error!?įind attached my modified makefile.win for CUDA 7.5 support. Tests with 5184K FFT length MHz / 2600 MHz:Ĭufftbench still recommends 5184K as optimal FFT length in my exponent case. Find the "CUDALucas2.05.1-CUDA7.5-Windows-圆4.exe" one directory up from your source files and be happy.Delete *temp files via "make -f makefile.win clean".Type "make -f makefile.win" in VS2012 圆4 Native Tools Command Prompt after having switched into CUDALucas/src directory with makefile.(Add 7.5 to if-else statements if missing) Edit given makefile.win for Win64: Adapt CUDA_VERSION and BIT (e.g.Install MS Visual Studio 2012 Professional Trial Edition (needed for 64bit, trial will not run out as only command line usage).version 7.5) (Manual installation, select only GPU Toolkit) HowTo compile CUDALucas for Win64, additional info to README: I have compiled "cudalucas-code-99-trunk" with CUDA 7.5 for Win64. Thanks in advance for replies and sorry if I missed a thread. Maybe they'll release the toolkit soon? Anything with regard to cuFFT in there? I noticed CUDA 8 is available at driver level: CUDA 8 driver release.Is this relevant fur CUDALucas? Is this relevant for Kepler? I read that CUDA 7 / 7.5 has a bug an Maxwell GPUs:.(Nvidia claims cuFFT improvements in CUDA 7: ) I read that airsquirrels is working on this here: Ĭould anybody provide a newer compile for evaluation? Maybe Win64, CUDA 7.5, CC 3.5? Has anyone tried it? (I have compiled CUDALucas years ago when CUDA was at 4.2 or so.) Question is: Will there be a speedup when recompiling against CUDA 7 / 7.5 / 8 ? I am running CUDALucas compiled against CUDA 6.5.
