GPULib enables users to access high performance computing with minimal modification to their existing programs. By providing bindings between Interactive Data Language (IDL) and large GPU libraries for general purpose computations, GPULib can accelerate new applications or be incorporated into existing applications with minimal effort. No knowledge of GPU programming or memory management is required.
GPULib is built on top of NVIDIA's Compute Unified Device Architecture (CUDA) platform. CUDA is supported by a wide range of NVIDIA products, including GeForce, Quadro, and Tesla cards.
Note: By default, GPULib supports only IDL 8.4 and CUDA 6.5. However, for interested GPULib Basic customers Tech-X may perform custom builds with different versions of IDL and CUDA.
GPULib is available with a 14-day money-back guarantee from the Tech-X Online Store.
