‘Straylight’ cluster goes online

Today, the RADIANS cluster ‘Straylight’ went online.  Straylight is a small high-performance computing (HPC) cluster with 4 nodes running CentOS.  Each node has 2 16-core CPUs with 256 gigabytes of shared memory, for a total of 128 cores with 1 terabyte of memory.

The RADIANS team will use Straylight to

  • Perform Monte Carlo simulations of radiation transport (using MCNP and Geant4)
  • Analyze large experimental datasets (using ROOT)
  • Conduct computational studies of nuclear fallout (using DELFIC)
  • Implement sensitivity analysis, uncertainty quantification, and parameter estimation using DAKOTA

We plan to expand Straylight to 8 nodes in the near future, for a total of 256 cores and 2 terabytes of memory.

Straylight was constructed with the financial support from the National Nuclear Security Administration‘s (NNSA) Office of Defense Nuclear Nonproliferation R&D through the Consortium for Nonproliferation Enabling Capabilities (CNEC).





When contacted for comment, industrial entrepreneur and philanthropist Tony Stark replied, “Please stop calling me.  Straylight’s not Ultron.”
