Keeping an eye on superfast transactions on Wall Street

Today, humans are generally removed from the process of trading on the financial markets; they have been replaced by algorithms and supercomputers. As such, trading speeds have progressed from microseconds to nanoseconds. Now, researchers are keeping up by using a supercomputer to catch a supercomputer.

Keeping on top of the data deluge

Today, biology is a data-driven science, intrinsically linked to computing.  However, dialogue between researchers and computer scientists about the analysis of genomic data is still far from 'organic'. The HPCBio group and the Texas Advanced Computing Center are addressing this issue with a distributed approach to computing resources, new software, and tailored customer services.

Building a new bridge between XSEDE and PRACE

At the XSEDE’12 conference in mid-July, John Towns, principal investigator for XSEDE discussed the challenges and successes of the US high-performance computing network's first year. XSEDE is building bridges between universities, users, and other cyber-infrastructures including the Open Science Grid for high throughput computing. Towns also mentioned the collaboration between XSEDE and the European computing infrastructure called PRACE and unveiled a new joint call to enable users to use both sets of resources.
