Cooling new Trinity supercomputer

Instead of city water, the new cooling plant will utilize water from Los Alamos National Laboratory’s Sanitary Effluent Reclamation Facility (SERF), saving millions of gallons of well water per year.

supercomputing hardware for cooling system


Installation of the cooling infrastructure to support the new Trinity supercomputer at Los Alamos National Laboratory is well underway. 

When Trinity becomes operational it will be the first platform able to accommodate finely resolved 3D calculations for full-scale, end-to-end weapons calculations


At Los Alamos' Strategic Computing Center, installation of the last meters of cooling infrastructure to support the Trinity Platform is well underway. The Trinity supercomputer is the first of the NNSA's Advanced Simulation and Computing program's advanced technology systems. Once installed, Trinity will be the first platform large and fast enough to begin to accommodate finely resolved 3D calculations for full-scale, end-to-end weapons calculations.

But the installation of such a powerful supercomputer is no small task. In order to accommodate Trinity and its successors, cooling and electrical subsystems supporting supercomputing in the SCC had to undergo major upgrades. 

Because energy conservation is a priority at Los Alamos, these upgrades included a shift to economical warm water cooling technology, as well as a decrease, since 2012, in the use of city/well water for cooling towers. Instead of city water, the new cooling plant utilizes water from LANL’s Sanitary Effluent Reclamation Facility (SERF), saving tens of millions of gallons of well water per year.
