ifbranching and comparison? ( i.e. if this 4-5 comparisons per elemet would be 10x slower than the same 4-5 comparisons on CPU it would be a bottleneck ) is there any optimization trick how to minizmizeifbranching and comparison slow down?
‣ Known Issues ‣ Some T4 FFTs are slower than expected. ‣ cuFFT may produce incorrect results for real-to-complex and complex-to-real transforms when the total number of elements across all batches in a single execution exceeds 2147483647. ‣ Some cuFFT multi-GPU plans may exhibit ...

The drawback is that it is a lot slower than working with a supported GPU. An article on the Premiere Pro team blog based on the information and questions in this forum thread has been posted, please check that out. Notes The author of this post is no ...
When using Numba, we have one detail we must pay attention to. Numba is a Just-In-Time compiler, meaning that the functions are only compiled when they are called. Therefore timing the first call of the functionwill also time the compilation stepwhich is in general much slower. We must ...
The authors report that the performance of a CUDA application ported to OpenCL run about 50 percent slower (Harvey & De Fabritiis, 2010). The authors attribute the performance reduction to the immaturity of the OpenCL compilers. They conclude that OpenCL is a viable platform for developing po...
are slower than the best handwritten compute kernels available in libraries like cuBLAS, cuDNN or TensorRT. According to the original authors of Triton, these systems generally perform well for certain classes of problems such as depthwise-separable convolutions; are often much slower than vendor lib...
I made the current OpenCL version, but actually it is slower than CPU even for GPUs with many ALUs. The reason is that I used a suboptimal strategy: I reimplemented the stack-based recursion mechanism in OpenCL but creating a software stack, which means that all ALUs in a group would wa...
However the test setup only has 100 Prime words and with large amount of words you could encounter slower performance. If you plan on using large wordlists - consider splitting and passing them to GPU in smaller batches.+GTable Chunk SizeIt's possible to pre-compute different size chunks for...
ZLUDA's GitHub also shows off some individual Geekbench compute scores and comparing OpenCL to this experimental CUDA implementation. While several benchmarks were significantly slower in ZLUDA, the Stereo Matching test was around 50% faster using ZLUDA than it was on OpenCL. That seems pretty pr...
