Edison
NERSC's newest supercomputer, named Edison after U.S. inventor and businessman Thomas Alva Edison, will have a peak performance of more than 2 petaflops (PF, or 1015 floating point operations per second) when fully installed in 2013. The integrated storage system will have more than 6 petabytes (PB) of storage with an I/O bandwidth of 140 gigabytes (GB) per second. The product is known as a Cray XC30 (internal name "Cascade"), and the NERSC acquistion project is known as "NERSC-7."
Edison will be installed in two phases; we are currently in phase 1. See the configuration page for more details.
File Storage and I/O
The Edison system has 4 different file systems; they provide different levels of disk storage, I/O performance and file permanence. Read More »
Performance and Optimization
Using a set of benchmarks described below, different optimization options for the different compilers on Edison. The compilers are also compared against one another on the benchmarks.
