Direct Linear Solvers on NVIDIA GPUs

DOWNLOAD DOCUMENTATION SAMPLES SUPPORT

The NVIDIA cuSOLVER library provides a collection of dense and sparse direct linear solvers and Eigen solvers which deliver significant acceleration for Computer Vision, CFD, Computational Chemistry, and Linear Optimization applications. The cuSOLVER library is included in both the NVIDIA HPC SDK and the CUDA Toolkit.


cuSOLVER Performance

cuSOLVER 11 leverages DMMA Tensor Cores automtically. DGX A100 is over 2x faster than DGX-2 despite having half the number of GPUs thanks to A100 and third generation NVLINK and NVSWITCH.
