WebFeb 8, 2024 · 1. thrust sort operations do a memory allocation "under the hood". This should be discoverable using nvprof --print-api-trace ... - you should see a cudaMalloc operation associated with each sort. This device memory allocation is synchronizing and may prevent expected overlap. If you want to work around this, you could explore using a … WebJul 17, 2024 · 我试图在我的"旧"推力代码中引入一些 CUB,因此从一个小示例开始比较 thrust::reduce_by_key 和 cub::DeviceReduce::ReduceByKey,两者都适用于 thrust::device_vectors. 代码的thrust 部分很好,但是CUB 部分天真地使用通过thrust::raw_pointer_cast 获得的原始指针,在CUB 调用后崩溃.我放了一个 …

WebFeb 28, 2024 · Using Thrust, I would try to implement this using a segmented reduction, i.e. thrust::reduce_by_key. By using a smart iterator as "key" (maybe a transform iterator taking a counting iterator and dividing the index by col) this should be fairly efficient. Indeed, this is a very new feature apparently. WebOct 19, 2024 · If anyone can find a thrust-only C++ minimal reproduction please share it here so we can take a look. I suspect that this may have been fixed in CTK 11.4 (Thrust/CUB 1.12) by NVIDIA/cub@63e2ad4, which fixed a lot of overflows that may result in InvalidConfiguration errors. novartis historical stock price

We should revise the using of CUB in the build system. Currently, we make an attempt to find it, and if not possible, we automatically download and include the package.This might just not be needed entirely for cuda 11 (as it might be included in the default cuda header paths), or the … WebOct 6, 2013 · It seems what you want to achieve depends on thrust::zip_iterator. You could either only replace thrust::sort_by_key by cub::DeviceRadixSort::SortPairs and keep thrust::gather, or zip values {1,2,3} into array of structures before using cub::DeviceRadixSort::SortPairs update After reading the implementation of thrust::gather, how to snorkel a beer
