cuda_graph的引入是为了解决kernel间launch的间隙时间问题的,尤其是有一堆小kernel,每个kernel启动也会带来一些开销,如果这些kernel足够多,那么就可能会影响系统的整体性能,cuda_graph的引入就是为了解决这个问题的,它会将stream内的kernel视为一整个graph,从而减少kernel的launch间隙时间。 cuda_graph基础 根据官方的源码...

mu-graph 包含三个层级,kernel-graph、block-graph 和 thread-graph,分别对应 cuda 程序执行的三个层级。 kernel-graph 的张量位于全局内存,算子包含两种,一种是预定义算子 (pre-defined operator),另一种是合成算子 (graph-defined operator)。其中预定义算子会直接对应 vendor-library 的 kernel,例如 matmul 对应 ...
This PR ports multi-step cuda graph block table fix from the flash_attn backend to flashinfer backend
This repository contains a CUDA-based multi-GPU vertex-centric graph processing framework based on Warp Segmentation and Vertex Refinement techniques. The options for this framework can be revealed by executing the program with no arguments. The vertex and edge structures and processing functions work ...
In this paper, we assume that all the tasks have a CUDA kernel, and when we refer to GPU or device, we assume an NVIDIA GPU that can support CUDA 10 and above. 3.1. GPU management The PaRSEC runtime dedicates a manager thread to manage all aspects of task execution on a GPU. Any...
Our evaluation includes a set of production class HPC benchmarks from the CORAL benchmarks [6], graph applications from Lonestar suite [43], compute applications from Rodinia [24], and a set of NVIDIA in-house CUDA benchmarks. Our application set covers a wide range of GPU application ...
SLEAP models were loaded and generated predictions on the latest image received from the camera in a separate thread from the acquisition and output generation. Using the detected poses, we classified whether the male was in an ‘approach’ pose based on the following criteria: $$({\textrm{...
2. The processing cluster 214 can be configured to execute many threads in parallel, where the term “thread” refers to an instance of a particular program executing on a particular set of input data. In some embodiments, single-instruction, multiple-data (SIMD) instruction issue techniques ...
