The NVIDIA® Tesla™ D870 deskside GPU computing system solves high performance computing (HPC) challenges for scientists, analysts, and other technical professionals by pairing two massively parallel Tesla C870 GPU computing processors in a deskside supercomputer.

The Tesla D870 deskside GPU computing system features two Tesla C870 GPU computing processors in a quiet deskside system that is suitable for the office environment. With 256 streaming processor cores, the CUDA C-language development environment and developer tools, and a range of applications already ported, the Tesla D870 delivers a dedicated deskside system to solve problems that previously required a large shared computing cluster.
