A Closer Look at the 95 Petaflop Tianhe-2A Supercomputer

In this podcast, the Radio Free HPC team looks at China's
massive upgrade of the Tianhe-2A supercomputer to 95 Petaflops peak
performance. As detailed in a new 21-page report by Jack
Dongarra from the University of Tennessee, the
upgrade should nearly double the performance of the system,
which is currently ranked at #2 on TOP500 with 33.86 Petaflops on
the Linpack benchmark.

The upgraded system, dubbed Tianhe -2A, should be completed in the
coming months. Details about the system upgrade were presented at
the conference opening session. While the current system derives
much of its performance from Intel Knights Corner co-processors,
the new system swaps these PCI devices out for custom-made 4-way
MATRIX-2000 boards, with each chip providing 2.46 Teraflops of peak
performance.

After that, we do our Catch of the Week:
