InfiniBand (IB) is a computer networking communications standard used in high-performance computing that features very high throughput and very low latency. It is used for data interconnect both among and within computers.
InfiniBand (IB) InfiniBand (IB) is one of latest computer-networking communications standard used in high-performance computing that features very high throughput and very low latency and it most commonly used to interconnect supercomputers. Mellanox and Intel are two main manufacturers of InfiniBand host bus adapters and network switches.
InfiniBand offers advantages such as a flatter topology, less intrusion on the server processor and lower latency. And Ethernet offers near ubiquity across the market for networking gear. The power.Over at the Dell HPC Blog, Olumide Olusanya and Munira Hussain have posted an interesting comparison of FDR and EDR InfiniBand. In the first post, we shared OSU Micro-Benchmarks (latency and bandwidth) and HPL performance between FDR and EDR Infiniband.Comparison of 40G RDMA and Traditional Ethernet Technologies Nichole Boscia,. One of the desirable features associated with InfiniBand, another network fabric technology, is its Remote Direct Memory Access (RDMA) capability. RDMA allows for communication between systems but can bypass the overhead associated with the operating system kernel, so applications have reduced latency and much.
RoCE and InfiniBand both offer many of the features of RDMA, but there is a fundamental difference between an RDMA fabric built on Ethernet using RoCE and one built on top of native InfiniBand wires. The InfiniBand specification describes a complete management architecture based on a central fabric management scheme which is very much in contrast to traditional Ethernet switched fabrics, which.Read More

This paper presents the design and implementation of the InfiniBand link layer with special efforts made for packet latency reduction and buffer space optimization. The link layer is designed to avoid any architectural conflict while its components are executed in parallel as far as possible. For high-speed packet processing with the various quality of service supports required by InfiniBand.Read More

The QDR data rate is closest to PCIe Gen 3. With a similar bandwidth and latency, a fabric based on PCIe should provide similar performance to that of an InfiniBand solution at the same data rate.Read More
We compare the performance with HCAs using PCI- X interfaces. Our results show that InfiniBand HCAs with PCI Express can achieve significant performance benefits. Compared with HCAs using 64 biU133 MHz PCI-X interfaces, they can achieve 20%-30% lower latency for small messages. The small message latency achieved with PCI Express is around 3.8 p. compared with the 5.0 ps with PCI-X. For large.Read More
InfiniBand is a new systems interconnect designed for Data Center Networks, and Clustering environments. Already, it is the fabric of choice for high-performance computing, education, life sciences, oil and gas, auto manufacturing and increasingly financial services applications. TIBCO, HP and Mellanox High Performance Extreme Low Latency Messaging (2012) With the recent release of TIBCO FTL.Read More
It is a bit hard to compare performance of jVerbs vs JSOR. The first one is message-oriented API, while the second hides RDMA behind stream-based API of Java sockets. Here are some stats. My test using a pair of old ConnectX-2 cards and Dell PowerEdge 2970 servers. CentOS 7.1 and Mellanox OFED version 3.1. I was only interested in latency test.Read More
