I've recently upgraded to Mathematica 9.0 on Ubuntu 12.04 with the latest Nvidia driver (304.64). I load CUDA by using, as usual, Needs["CUDALink`"]. CUDAQ[] reports True. CUDAInformation[] reports: {1 -> {"Name" -> "GeForce GT 330M", "Clock Rate" -> 1265000, "Compute Capabilities" -> 1.2, "GPU Overlap" -> 1, "Maximum Block Dimensions" -> {512, 512, 64}, "Maximum Grid Dimensions" -> {65535, 65535, 1}, "Maximum Threads Per Block" -> 512, "Maximum Shared Memory Per Block" -> 16384, "Total Constant Memory" -> 65536, "Warp Size" -> 32, "Maximum Pitch" -> 2147483647, "Maximum Registers Per Block" -> 16384, "Texture Alignment" -> 256, "Multiprocessor Count" -> 6, "Core Count" -> 48, "Execution Timeout" -> 1, "Integrated" -> False, "Can Map Host Memory" -> True, "Compute Mode" -> "Default", "Texture1D Width" -> 8192, "Texture2D Width" -> 65536, "Texture2D Height" -> 32768, "Texture3D Width" -> 2048, "Texture3D Height" -> 2048, "Texture3D Depth" -> 2048, "Texture2D Array Width" -> 8192, "Texture2D Array Height" -> 8192, "Texture2D Array Slices" -> 512, "Surface Alignment" -> 256, "Concurrent Kernels" -> False, "ECC Enabled" -> False, "TCC Enabled" -> False, "Total Memory" -> 1073414144}} Thus it seems that everything works. But if try to perform the following: randM = RandomReal[1, {1000, 1000}]; CUDADot[randM, randM]; I get: CUDADot::notinit: CUDALink is not initialized. What does it mean? I already tryied googling looking for the error message... nothing found. Thanks in advice to whom can shed light. -- ...and I will make them pay for what they've done! (J.L. Picard)
