![]() I needed to do this because my input data size required more than 65535 blocks, which is more than is allowed in gridDim.x or gridDim.y. I’ve actually gotten my kernels to work, but yesterday, while testing various sizes of my input data, I ran into some some complications which I’ve not yet been able to solve up till now.Īctually, the problem arose when I tried changing my grid from a one dimensional grid to a two dimensional grid. Supports MultiDevice Co-op Kernel Launch: Yesĭevice PCI Domain ID / Bus ID / location ID: 0 / 1 / 0ĭeviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 9.I am new to cuda and trying to get my feet wet. Support host page-locked memory mapping: Yesĭevice supports Unified Addressing (UVA): Yes Maximum number of threads per multiprocessor: 2048 Maximum number of threads per block: 1024 Max dimension size of a thread block (x,y,z): (1024, 1024, 64) - max block size Max dimension size of a grid size (x,y,z): (2147483647, 65535, 65535) - max grid sizeĬoncurrent copy and kernel execution: Yes with 2 copy engine(s) Total number of registers available per block: 65536 Total amount of shared memory per block: 49152 bytes As illustrated by Figure 2, other languages, application programming interfaces, or directives-based approaches are supported, such as FORTRAN, DirectCompute, OpenACC. In this tutorial, we will use one-dimensional thread blocks and only one block in our. CUDA comes with a software environment that allows developers to use C++ as a high-level programming language. Total amount of constant memory: 65536 bytes A GPU can run many concurrent Kernels each of which uses a grid. Maximum Layered 1D Texture Size, (num) layers 1D=(32768), 2048 layers ( 5) Multiprocessors, (128) CUDA Cores/MP: 640 CUDA Cores Total amount of global memory: 4040 MBytes (4235919360 bytes) usr/local/cuda/samples/1_Utilities/deviceQuery/deviceQueryĬUDA Driver Version / Runtime Version 9.2 / 9.0ĬUDA Capability Major/Minor version number: 6.1 I won't go into the details, it's similar to Printf("I am the CPU: Hello World ! \n") Hello>( ) // Launch a 2 dim grid of threads ThreadColId = blockIdx.y * blockDim.y + threadIdx.y ThreadRowID = blockIdx.x * blockDim.x + threadIdx.x ThreadID = blockDim.x * blockIdx.x + threadIdx ĭim3 blockShape = dim3( MaxXBlkDim, MaxYBlkDim ) // = dim3( MaxXBlkDim, MaxYBlkDim, 1 ) ĭim3 gridShape = dim3( MaxXGridDim, MaxYGridDim ) // = dim3( MaxXGridDim, MaxYGridDim, 1 )
