 Point cloud computation has become an increasingly more important workload for autonomous driving and other applications. Unlike dense 2D computation, point cloud convolution has **sparse** and **irregular** computation patterns and thus requires dedicated inference system support with specialized high-performance kernels. While existing point cloud deep learning libraries have developed different dataflows for convolution on point clouds, they assume a single dataflow throughout the execution of the entire model. In this work, we systematically analyze and improve existing dataflows. Our resulting system, TorchSparse, achieves **2.9x**, **3.3x**, **2.2x** and **1.7x** measured end-to-end speedup on an NVIDIA A100 GPU over the state-of-the-art MinkowskiEngine, SpConv 1.2, TorchSparse (MLSys) and SpConv v2 in inference respectively. 
 
+## News
+
+**\[2023/6/18\]** TorchSparse++ has been released and presented at CVPR 2023 workshops on autonomous driving. It achieves 1.7-2.9x inference speedup over previous state-of-the-art systems.
+
+**\[2022/8/29\]** TorchSparse is presented at MLSys 2022. Talk video is available [here](https://www.youtube.com/watch?v=IIh4EwmcLUs).
+
+**\[2022/1/15\]** TorchSparse has been accepted to MLSys 2022, featuring adaptive matrix multiplication grouping and locality-aware memory access.
+
+**\[2021/6/24\]** TorchSparse v1.4 has been released.

-TorchSparse achieves superior mixed-precision training speed compared with MinkowskiEngine, TorchSparse-MLSys and SpConv 2.3.5. Specifically, it is **1.16x** faster on Tesla A100, **1.27x** faster on RTX 2080 Ti than state-of-the-art SpConv 2.3.5. It also significantly outperforms MinkowskiEngine by **4.6-4.8x*** across seven benchmarks on A100 and 2080 Ti. Measured with batch size = 2.
