Los Alamos National Laboratory has a program for (competed) access to institutional parallel supercomputing resources open to LANL scientists and engineers. This website is home to two major projects operational under this program: one focusing on particle-based simulations in cosmology and beam physics, the other investigating quantum dynamical systems. The projects include personnel from D, CCS, ISR, T, and X Divisions as well as collaborators from several universities and national laboratories. Machines utilized include QSC (1000 Alpha, 4 TB), Pink (2048 Xeon, 2 TB), and Mauve (256 Itanium, 1 TB).

HPC Experience: The researchers taking part in these projects have wide experience on parallel HPC platforms and have been among the pioneers in the application of parallel processing in several fields: accelerator physics, cosmology, field theory, and plasma physics. The team has a collective experience of over 100 man-years in parallel computing (3 DOE and NASA Grand Challenges, 3 SciDAC projects, 5 Gordon Bell awards).

Cosmology: Dark energy, dark matter, primordial fluctuations, clustering of matter and galaxy formation, and the ionization history of the Universe are the frontiers of cosmology. Large scale simulations as an integral element of theoretical understanding, data analysis, and mission planning are essential to how cosmology is done today.

Accelerator Science: The design of the next generation of accelerators requires a new level of simulation capability as designers push the boundaries of beam intensity, energy, and system complexity. All near- and far-future accelerators have very challenging modeling requirements that require aggressive utilization of high performance computing.

Quantum Dynamical Systems: Real-time evolution of quantum systems encompasses topics as diverse as mesoscopic devices, information processing, feedback control, Bose-Einstein condensates, heavy-ion collisions, and the dynamics of the early Universe. Many advances in these areas have relied on the enormous growth of computational resources in the past decade.
