Hello, I'm new here and I just heard about x10 language, although I'm rather focused on yet another way of using CUDA-derived technologies, therefore giving x10's CUDA capabilities a try is the very first thing I want to do before I go any deeper into x10. Unfortunately, I stuck on this infamous "async 72 is not a CUDA kernel" problem - I tried to run x10 CUDA examples on three different machines and three different CUDA toolkit versions with four different settings (all with different nvidia displays and plain .cu CUDA examples working): 1. x86 Gentoo Linux CUDA 4.2 2. x86 Gentoo Linux CUDA 3.2 (manual downgrade) 3. x86_64 Gentoo Linux CUDA 4.2 4. x86_64 MacOSX 10.6.8 CUDA 5.0
The results were always the same: "not a CUDA kernel" on all x10 CUDA examples (except CUDATopology which actually works, exactly the same case as in Avinash Malik's post). I first tried SVN snapshot then x10-2.3.0-src.tar.bz2, result still the same (mabye I should check older releases too?): bash-3.2$ X10RT_ACCELS=ALL ./CUDABlackScholes Using the GPU at place Place(1) This program only supports a single GPU. Running 512 times on place Place(1) X10RT: async 72 is not a CUDA kernel. Abort trap (that's copied from the MacOSX build) simple CUDA status program shows following: bash-3.2$ ./mp0 There is 1 device supporting CUDA Device 0 name: GeForce 320M Computational Capabilities: 1.2 Maximum global memory size: 265027584 Maximum constant memory size: 65536 Maximum shared memory size per block: 16384 Maximum block dimensions: 512 x 512 x 64 Maximum grid dimensions: 65535 x 65535 x 1 Warp size: 32 Can anyone confirm that these x10 CUDA examples are working for anyone? Or worked in any past release? Somehow I don't believe that things written in http://x10-lang.org/documentation/practical-x10-programming/x10-on-gpus.html page aren't not quite truth...
