TileLink: Generating Efficient Compute-Communication Overlapping Kernels using Tile-Centric Primitives 最近各大厂都开始下一轮更为细致的优化工作,不局限于算法,更多的是 infra,考验各家硬实力的时候开始了。没办法,我最近也在看这方面的工作,一起学习下字节的最新计算-通信优化工作,想法很好,实现也很字节。喜欢这个...
id | all_reduce_prim_impl.id: # Prefer larger communication ops over smaller ones return -node.bsym.args[0].numel # We want to keep the `reduce` close to it's producer # (which is close to the original place in the trace). return order_in_trace[node.bsym]...
1F1B流程 使用--no-overlap-p2p-communication关闭P2P通信掩盖,则每张卡的每个1F1B整体结束后,与相关的 PP rank 收发所需的 input_tensor,output_tensor_grad,因此上图每张卡连续的1F1B之间实际上要做PP通信 关闭--no-overlap-p2p-communication开启P2P通信掩盖,1F结束之后立刻发起异步 send_next 和 recv_prev,1...
2. Communication channels are opened to prepare for the traffic between the UI and the Application Executable. ‣ For Interactive Profile activities, a SOCKS proxy is started on the host machine. ‣ For Non-Interactive Profile activities, a remote forwarding channel is opened on the target ...

Furthermore, we address the time critical parallel tasks, namely the distributed matrix–matrix multiplication to calculate the overlap of the electronic states with the β-projectors and the 3-d FFT of the electronic states. For both routines, we introduce overlapping computation and communication ...
To maintain streaming packet processing while retaining reuse-based compute-intensive processing we propose a bulk-streaming message passing interface along with a methodology to tune communication-computation overlap. As a proof of concept, we evaluate the efficiency of the FPGA assistant with the ...
Added interKernelCommunication sample CUDA application to show how to use NVIDIA Nsight Compute to profile kernels that depend on each other and must be launched concurrently. Refer to the README.TXT file and sample code under extras/samples/interKernelCommunication. NVIDIA Nsight Compute Added SASS...
When entering play mode we'll now see a single colored unit cube sitting at the origin. It's the same cube getting rendered once per point, but with an identity transformation matrix so they all overlap. Performance is a lot better than before, because almost no data needs to be copied ...
(e.g., IoT, edge, cloud). The resulting continuum infrastructure includes heterogeneous computing, storage, and networking resources, which are usually geographically distributed and, thus, likely characterized by non-negligible communication delays. Moreover, the infrastructure exhibits dynamic working ...
