UT Austin is home to the Texas Advanced Computing Center (TACC), whose flagship cluster, Stampede2, has 4,200 Intel Knights Landing nodes, each with 68 cores, 96GB of DDR RAM, and 16GB of high speed MCDRAM, 1,736 Intel Xeon Skylake nodes, each with 48 cores and 192GB of RAM, 100 Gb/sec Intel Omni-Path network with a fat tree topology employing six core switches, and two dedicated high performance Lustre file systems with a storage capacity of 31PB. Its peak performance is 18 petaflops. In Summer 2019, a new petascale computing system, Frontera, which will have a peak performance of 35-40 petaflops, will be commissioned.
UCSB has six computational workstations (2.4GHz quad-core CPU, 2 GB RAM, 200 GB HDD) as desktop machines for graduate and undergraduate researchers to develop codes, visualize results, and perform analyses. Extensive computational resources are available through the UCSB Center for Scientific Computation (CSC), managed jointly by the California NanoSystems Institute (CNSI) and Materials Research Laboratory (MRL).
LBNL utilizes the National Energy Research Scientific Computing Center (NERSC), the primary scientific computing resource at LBNL. We will use NERSC's Cori machine, a Cray XC40 with a peak performance of about 30 petaflops. Cori is comprised of 2,388 Intel Xeon "Haswell" processor nodes, 9,688 Intel Xeon Phi "Knight's Landing" nodes, and a 1.8 PB Cray Data Warp Burst Buffer and a peak performance of 27.8 Petaflops.
