Plasmonics Simulations

There are a number of facilities on campus which allow us to do very sophisticated simulations of plasmonic devices.

RA High Performance Computer (HPC)

  • 2144 processing cores in 268 nodes
    • 256 nodes with 512 Clovertown E5355 (2.67 GHz)
      • (quad core dual socket)
      • 184 with 16 Gbytes & 72 with 32 Gbytes
    • 12 nodes with 48 Xeon 7140M (3.4 GHz)
      • (quad socket dual core)
      • 32 Gbytes each
  • Memory
    • 5,632 Gbytes ram (5.6 terabytes)
    • 300 terabyte disk
    • 16/32 gigabytes RAM per node
    • Library of Congress has 20 terabytes
    • All the films made in the world in 1989 would take up 166 terabytes
  • Performance
    • 17 teraflop sustained performance
    • like every human on the planet doing 2500 calculations per second

NVIDIA Tesla S1070 GPU Computer: Special purpose computing accelerators, such as graphic processing units, (GPU) have become an important platform for parallel high performance scientific computing. CSM recently took delivery of and installed a Nvidia Tesla S1070 system. This 1U rack mountable system contains 4 of the Nvidia Quadro FX 5600 GPU cards and has a peak computing performance of 4 trillion floating point operations per second, or 4 Teraflops. This new Tesla system is front-ended by one of the RA nodes. Each of the 4 graphics processing units (GPU) on the Tesla has 240 processing cores and 4 Gbytes of memory for a total of 960 cores and 16 Gbytes. The individual GPUs are connected to the front-end node via a PCI connector.

COMSOL Multiphysics: Finite element simulation is one of the most powerful numerical methods available. COMSOL Multiphysics, a commercial finite element solver allows for simple connection of different physical differential equations. This is important when simulating devices where many types of physics interact. For instance in solar technology, electromagnetic wave simulation is combined with charge transport to form a very non-linear set of differential equations which are coupled.

In addition to COMSOL Multiphysics, we utilize Mathematica, Matlab, and low level programming languages such as C, C++, and Fortran for different simulations.
