High frequency trading (HFT), often called algorithmic or low latency trading, relies on fast computers and even faster networks to execute trades in sub-second and even sub-millisecond timeframes. It has generated massive profits for those firms skilled enough to handle the complexities of the software and hardware. As such, it has become the dominant method for equity trading in the US, but it’s popularity is expanding worldwide, especially Asia. HPCwire got the opportunity to ask Chuck Chon, chief technology officer of SBI Japannext, about the HFT business in Japan.
In a position paper for community input at NSF’s Future of High Performance Computing Workshop in early December, Calit2 Director Larry Smarr reviewed the successes, failures and continuing challenges of the NSF supercomputing program that he helped create.
So far, 10GbE has been a high-end luxury for environments that want maximum performance regardless of cost, but that’s changing fast. The per-port pricing gap between 10GbE and alternate network options is narrowing rapidly as more vendors increase the competitive pressure on pricing for related components.
Welcome to the era of the computational Web. Wolfram Alpha, Stephen Wolfram’s online “computational knowledge engine” debuted on Friday evening, and was officially launched on Monday on its Web site.
Late last week Yahoo announced that it had expanded the circle of universities with access to M45, the 4,000 core cluster that the company made available for “internet-scale” research in November of 2007.
