Genesis GE-i940 Tesla

On September 28, 2009, a workstation Genesis GE-i940 Tesl, based on both GPGPU* and nVidia/CUDA** Technologies has been installed at DSA/LabMNCP.

It is a testbed for developing advanced simulation in the following research field:

  • Stochastic simulation;
  • Molecular Dynamics;
  • Atmospheric and climate modeling;
  • Weather forecast investigation;
  • Grid/Cloud Hybrid Virtualization;

“GPGPU stands for General-Purpose computation on Graphics Processing Units, also known as GPU Computing. Graphics Processing Units (GPUs) are high-performance many-core processors capable of very high computation and data throughput. See more here.”

**
“NVIDIA® CUDA™ is a general purpose parallel computing architecture that leverages the parallel compute engine in NVIDIA graphics processing units (GPUs) to solve many complex computational problems in a fraction of the time required on a CPU. See more here. “
