What RDMA Is RDMA (Remote Direct Memory Access) is a technology created to solve the delay of server-side data processing in network transmission. With TCP/IP transmission, data passes through the network stack, then through the NIC to be sent; after the receiver receives it, the data is reassembled according to sequence numbers.微信公众号RDMANetworkHigh Performance ComputingHardwareAIOperationshttps://www.chenshaowen.com/en/blog/infiniband-network-and-useful-commands.htmlSat, 02 Nov 2024 00:00:00 +0000Sat, 02 Nov 2024 00:00:00 +0000https://www.chenshaowen.com/en/blog/infiniband-network-and-useful-commands.html1. InfiniBand Network InfiniBand (abbreviated IB) is a computer network communication standard for high-performance computing. It offers extremely high throughput and very low latency, and is used for data interconnection between computers. InfiniBand is also used as a direct or switched interconnect between servers and storage systems, as well as between storage systems themselves.微信公众号InfiniBandNetworkHigh Performance ComputingHardwareOperationshttps://www.chenshaowen.com/en/blog/nvidia-gpu-cores-and-architecture-evolution-history.htmlSun, 25 Aug 2024 00:00:00 +0000Sun, 25 Aug 2024 00:00:00 +0000https://www.chenshaowen.com/en/blog/nvidia-gpu-cores-and-architecture-evolution-history.html1.

So I spent a little time putting together the common AI chip interconnect solutions. 1. Point-to-Point Interconnect In a traditional PCIe system, data transfer between AI chips goes over PCIe, which cannot meet the demands of large-scale data transfer.微信公众号AIChipInterconnectHardwareOperationshttps://www.chenshaowen.com/en/blog/common-gpu-operation-and-fault-handling.htmlMon, 18 Mar 2024 00:00:00 +0000Mon, 18 Mar 2024 00:00:00 +0000https://www.chenshaowen.com/en/blog/common-gpu-operation-and-fault-handling.htmlContent referenced or recorded while handling faults, continuously updated. 1. XID Error Events XID is NVIDIA’s error code. You can retrieve it with the command: 1 dmesg -T | grep -i "NVRM: Xid" or 1 journalctl --since `date -d "10 days ago" "+%Y-%m-%d"`|grep Xid The XID lets you locate the fault.微信公众号GPUNVIDIAAIHardwareOperationsTroubleshootinghttps://www.chenshaowen.com/en/blog/basic-usage-of-nvidia-smi.htmlThu, 01 Feb 2024 00:00:00 +0000Thu, 01 Feb 2024 00:00:00 +0000https://www.chenshaowen.com/en/blog/basic-usage-of-nvidia-smi.html1.
