Nvidia Tesla GPU

The Tesla graphics processing unit (GPU) is nVidia's third brand of GPUs. It is based on high-end GPUs from the G80 (and on), as well as the Quadro lineup. Tesla is nVidia's first dedicated General Purpose GPU. The Tesla series takes its name from pioneering electrical engineer Nikola Tesla.

Tesla overview

Because of their very high computational power (measured in floating point operations per second or FLOPS) compared to previous microprocessors, the Tesla products target the high performance computing market.[1] The lack of ability to output images to a display[2] is the main difference between Tesla products and ordinary video cards. For equivalent single precision output, Fermi-based nVidia Geforce cards have four times less dual-precision performance. Tesla products primarily operate[3]:

  • in simulations and in large scale calculations (especially floating-point calculations)
  • for high-end image generation for applications in professional and scientific fields

with the use of OpenCL or CUDA.

As of 2011 nVidia Teslas power the second-fastest supercomputer in the world, Tianhe-1A, in Tianjin, China.

Notes

  • 1 Specifications not specified by NVIDIA are assumed to be based on the GeForce 8800GTX
  • 2 Specifications not specified by NVIDIA are assumed to be based on the GeForce GTX 285
  • 3 A host system/server is required to connect to the 1U GPU computing server by the PCI Express card (similar set-up as the Nvidia Quadro Plex)
  • 4 Core architecture version according to the CUDA programming guide.
  • 5 With ECC on, a portion of the dedicated memory is used for ECC bits, so the available user memory is reduced by 12.5%. (e.g. 3 GB total memory yields 2.625 GB of user available memory.)
  • 6 Fermi implements the new fused multiply–add (FMA) instruction for both 32-bit single-precision and 64-bit double-precision floating point numbers (GT200 supported FMA only in double precision) that improves upon multiply-add by retaining full precision in the intermediate stage.[10]
  • For the basic specifications of Tesla, refer to the GPU Computing Processor specifications.
  • Performance figures are for single-precision except where noted.
  • NVIDIA Tesla Supercomputers are also available with up to 8x Fermi GPUs from Manufacturers.
