NERSC Cabinet Cori Zoom


Cori is NERSC's newest supercomputer system (NERSC-8). It is named after American biochemist Gerty Cori. The Cori system will be delivered in two phases with the first phase online now and the second expected in mid-2016.  The Phase-1 system is a Cray XC system based on the Haswell multi-core processor that will include a number of new features that will benefit data-intensive science. The second phase of the Cori system will be installed and merged with Phase 1 in mid-2016. Phase 2 will be based on the second generation of Intel®  Xeon Phi™ Product Family, called Knights Landing (KNL) Many Integrated Core (MIC) Architecture.

Cori Phase I

The Cori Phase 1 (also known as the "Cori Data Partition") system utilizes Intel Haswell processors and provides approximately the same sustained application performance as the Hopper system. Cori Phase 1 has a number of new features to support data intensive science. Read More »

Running Jobs

Running jobs on Cori is very similar to running jobs on Edison and Hopper.  The key differences are Cori uses a new batch scheduler, SLURM Cori Phase 1 has 32 cores per node, compared to 24 on Edison  Cori Phase 1 has 128 GB of memory per node, compared to 64 GB on… Read More »

Cori Phase II

Cori Phase 2 will be arriving in the summer of 2016! Cori Phase 2 will feature the Intel Knights Landing manycore architecture. Read More »

Application Porting and Performance

We expect many applications will need to make code modifications in order to run efficiently on Cori's Knights Landing manycore architecture. To run well on Cori, your application will need to have good thread scalability, take advantage of vectorization opportunities, and manage multiple hierarchies of memory effectively. Read More »

Burst Buffer

The Burst Buffer on Cori is a layer of non-volatile storage that sits between the a processors' memory and the parallel file system. The burst buffer will serve to accelerate I/O performance of application on Cori. Read More »
