Supersizing the supercomputers |
| TheallIneed.com/NC&T/PNNL |
The current vision of future supercomputers calls for them to be very heterogeneous--for example, rather than a central processing unit (CPU) with memory, disk and interconnect, the CPU will contain cores of smaller CPUs making up a larger whole--and have different types of processors, such as vectors and field programmable gate arrays (FPGAs). The location and type of memory will be more complex as well.
High performance components--encapsulated chunks of software that perform specific tasks--will be coupled to a dynamic framework that allows the scientists and the software to dynamically determine the algorithms or modifications to algorithms that will perform well on a particular architecture.
Multiple levels of parallelism will be explored, including parallelism at the component level, parallelism within the component, parallelism within a subroutine and threading.
These supercomputers of the future will provide orders of magnitude more computing power, but their increasing complexity also requires experts in computational science, mathematics and computer science working together to develop the software needed for the science.

| Quotes | Figures wont lie, but liars will figure.
General Charles H. Grosvenor.
He thought the formula for water was H-I-J-K-L-M-N-O (H-to-O).
He uses statistics as a drunken man uses lampposts — for support rather than illumination. — Andrew Lang.
