For CPU: For GPU: As we can see, GPU is much slower than CPU. The reason is: we called Dnoisefun.m and noisefun.m a lot; 'interp1' should be faster on GPU but didn't seem so; the indexing operation 'result(result<0)' is super slow on GPU. ...
My current code runs significantly faster on the CPU, even without parfor or spmd, than it does on the GPU. You can run the attached code, if you would like to try it. My question is: how can I make this faster on the GPU, if a GPU is...

Matlab计算速度挺快的，开发速度特别快；C++の运行速度那就是薛定谔小车，有时候飞快，有时候根本不存在，...
cui xyon 23 Jun 2024 Are there any other reasons why the program might run so much slower than in previous version of matlab... Fangjun Jiangon 23 Jun 2024 It could be some "optimization gone wrong". We've had such cases and the Mathworks acknowledged and exp...
so I coded my own linear interpolation function to run on the GPU using arrayfun. My function is faster than griddedInterpolant but slower than interpn. I was wondering if anyone could see a way to speed up my function. Or do you think it would benefit from compiling it as a GPU MEX...
Applications that do not satisfy these criteria might actually run slower on a GPU than on a CPU. GPU Computing in MATLAB Before continuing with the wave equation example, let's quickly review how MATLAB works with the GPU. FFT, IFFT, and linear algebraic operations are among more than 100...
So Matrix-Matrix multiplication is faster on this hardware using AOCL but Cholesky decomposition is slower for this matrix size. Over to you I was very excited by this recent update and hope that you are too. If you give it a try, let me know how you get on in the comments section ...
Multi-device/GPU reconstruction only supports OSEM and MLEM. Implementation 4 (OpenMP CPU) supports only one prior/algorithm at a time. LMF output currently has to contain the time stamp (cannot be removed in GATE) and detector indices. The source location needs to be included if it was sele...
funtype - defines the actual function that is used. Can be either "gpu", "cpu" or "matlab". While "matlab" is slower, it is easier to do some debugging and see the intermediate results. COMPILATION If you cannot use the binaries for C++ CPU and GPU versions, you need to compile the...
