• CUDA is the parallel programming model to write general purpose parallel programs that will be executed on the GPU.Bank conflicts in GPUs are specific to shared memory and it is one of the many reasons to slow down the GPU kernel.
• Performing matrix multiplication on these two tiles creates a tile of partial sums in the C elements. When the next pair of tiles from A and B are retrieved, the partial sums are further incremented, until eventually the full strips have been processed and the final answers are available.

• 5.9 Matrix Multiplication (Tiled) This example multiples two square matrices together using multiple blocks and shared memory. Each thread block is assigned a "tile" of the resulting matrix and is responsible for generating the elements in that tile. Each thread in a block computes one element of the tile.
• the structure of CUDA. Forcing the student to use mul-tiple blocks makes the kernel invocation syntax more clear. We felt that shared vs. global memory should be explained to students and could even be taught sepa-rately by having students create tiled matrix multiplica-tion programs both with and without shared memory.

• For the tiled single-precision matrix multiplication kernel as shown in Lecture 4.4, assume that the tile size is 32X32 and the system has a DRAM bust size of 128 bytes. How many DRAM bursts will be delivered to the processor as a result of loading one M-matrix tile by a thread block? (A) 16 (B) 32 (C) 64 (D) 128 Answer: (B) Explanation.
• While Thrust has a "backend" for CUDA devices, Thrust interfaces themselves are not CUDA-specific and do not explicitly expose CUDA-specific details (e.g., cudaStream_t parameters). CUB, on the other hand, is slightly lower-level than Thrust. CUB is specific to CUDA C++ and its interfaces explicitly accommodate CUDA-specific features.

• Apr 21, 2011 · We choose a sub matrix block size : and rewrite the matrix A of size as a block matrix: Where is . Like we did in the LU Decomposition section we can easily compute the first row and the first column of the L and U block matrices and apply the process iteratively to . As the usual rules of matrix multiplication hold with block matrices we can write

This is the second in the series of posts related to matrix multiplication.. Example 1. Consider the above example for matrix multiplication. We can think of the (1,1) entry of the product as an inner product of the first row and the first column of the two matrices in the product: 650 = 1 · 21 + 5 · 22 + 9 · 23 + 13 · 24.

Note that if you are dealing with large matrices, you may wish to check out the CUBLAS functions for matrix multiplication; a dot() function that uses those functions is available in scikit-cuda , although the Python code that makes the function easy to use may impose some noticeable overhead if you plan to invoke it several thousand times. If you are interested, please write me a short note here indicating your background in CUDA programming, and try to give me an example of your programming abilities (e.g., Github) and writing abilities (e.g., papers on ArXiv or anything else). It's not necessary to be a CUDA expert, provided you can learn what's needed quickly.
