#MEMORY DIM3 FREE#
Free device memory cudaFree(Md.elements) © David Kirk/NVIDIA and Wen-mei W. Allocate the device memory where we will copy M to Matrix Md Md.width = WIDTH Md.height = WIDTH Md.pitch = WIDTH int size = WIDTH * WIDTH * sizeof(float) cudaMalloc((void**)&Md.elements, size) // Copy M from the host to the device cudaMemcpy(Md.elements, M.elements, size, cudaMemcpyHostToDevice) // Read M from the device to the host into P cudaMemcpy(P.elements, Md.elements, size, cudaMemcpyDeviceToHost). To answer your query about the specific requirements for the memory, the Precision T7500 supports 1066 MHz and 1333Mhz DDR3 memory cards. Please let me know if I have understood correctly. – One thread handles one element of P – M and N are loaded WIDTH times from global memory Memory failure detected at DIMM3' but if you leave the DIMM3 slot and tried slots 1,2 and 4,5 then the system complains that 'Configuration is not optimal'. Leave shared memory usage until later Local, register usage Thread ID usage Memory data transfer API between host and device A straightforward matrix multiplication example that illustrates the basic features of memory and thread management in CUDA programs – – – –.Global Memory © David Kirk/NVIDIA and Wen-mei W. dim3 blocks( nx, ny, nz ) // cuda 1.x has 1D and 2D grids, cuda 2.x adds 3D.
