Cloud, Wall Street and the Low Latency Imperative

Jun 17, 2010 |

The battle for the lowest possible latency has been raging in the financial services sector for years but is not the most critical factor for every segment of the industry. While low latency will be enhanced in cloud developments, for now it appears that only this small non-latency-obsessed market can be reached by cloud vendors.

Remote Direct Memory Access Networking for HPC: Comparative Review of 10GbE iWARP and InfiniBand

Feb 24, 2010 |

Cluster computing systems have caused disruptive changes in the HPC market. One consequence of the range of requirements for cluster networking is that the leading interconnects in HPC are Gigabit Ethernet (GbE), which is based on Ethernet networking standard, and InfiniBand, delivering upwards of 10X performance vs. GbE. Both show significant deployment in HPC.
