Nvidia Tesla

The Tesla graphics processing unit (GPU) is Nvidia's third brand of GPUs designed as a general purpose GPU. It is based on high-end GPUs from the G80 series onward with elements from the Quadro series. The Tesla series takes its name from pioneering electrical engineer Nikola Tesla.

Tesla overview

With their very high computational power (measured in floating point operations per second or FLOPS) compared to microprocessors, the Tesla products target the high performance computing market.[1] As of 2012, Nvidia Teslas power some of the world's fastest supercomputers, including Titan at Oak Ridge National Laboratory and Tianhe-1A, in Tianjin, China.

The lack of ability to output images to a display was the main difference between Tesla products and the consumer level GeForce cards and the professional level Quadro cards, but the latest Tesla C-class products include one Dual-Link DVI port.[2] 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.

Nvidia intends to offer ARMv8 processor cores embedded into future Tesla GPUs as part of Project Denver.[4] This will be a 64-bit follow on to the 32-bit Tegra chips.

Tesla itself will be followed by the TB/s Volta in 2016.[5]

Market

The defense industry currently accounts for less than a sixth of Tesla sales, but Sumit Gupta predicts further sales to the geospatial intelligence market.[6]

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.[16]
  • Performance figures are for single-precision except where noted.
  • NVIDIA Tesla Supercomputers are also available with up to 8x Fermi GPUs from manufacturers.
