Lassen Supercomputer

Partnership with the Stockpile Stewardship Program

The M&IC platforms are part of the high performance computing (HPC) environment at LLNL. Some platforms represent primarily Stockpile Stewardship Program (SSP) investments; others represent divided investments between multiple programs (including the SSP) and the Institution.

The support infrastructure (everything but the compute platforms) is covered both by M&IC and by the SSP, and the partners share the resources. The Center balances these investments according to the utilization of the broad support infrastructure by the partners. The end result is a more capable HPC environment than any program (or the Institution) could afford alone.

Computing Platforms

Investing programs or projects are invited to contact one of the M&IC Points of Contact regarding access rights.

Available computing platforms include Borax, Catalyst, Lassen, Quartz, Ray, and Syrah. A large data store on the green network called Green Data Oasis provides Web and FTP access to scientific data you wish to share with remote colleagues. 


Pascal is the M&IC visualization server, which has a partition available for GPGPU usage as well as GPUs on all other compute nodes.  A variety of software is supported for data analysis and visualization.

The ASC Program built and maintains physically large and high resolution displays that are used for demonstrations at high-level reviews, press conferences, and visits. They may also be used by scientists who wish to show their visualizations on a high-resolution display. 

Programs wishing to collaborate with our visualization specialists may contact Jane Herriman, LC Vis project lead, at 925-422-0398, or send e-mail to lc-vis [at] llnl.gov (lc-vis[at]llnl[dot]gov) .

Storage Environment

The storage environment consists of an uncompressed archive managed by High Performance Storage System (HPSS) software.
