CUDA is a parallel computing platform and programming model from Nvidia. It allows developers to leverage the computing power of the graphics processing unit (GPU). The Open Computing Language (OpenCL) is a framework for writing programs that execute across heterogeneous platforms consisting of central processing units (CPUs), graphics processing units (GPUs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs) and other processors or hardware accelerators.
Efficiently implementing applications in CUDA or OpenCL for large code bases is challenging and requires specialized knowledge. Our team of expert GPU programmers provides training to give clients a solid background in the theoretical, software, and computational aspects of CUDA and OpenCL GPU implementation. The training covers everything from suitability assessments and profiling over initial CPU to GPU code migration to advanced performance tuning and maintenance.
Achieving maximum performance on GPUs goes far beyond learning the CUDA or OpenCL languages. For example, different architectures require specialised tuning, register usage should be optimised, latencies hidden, the memory layout and access patterns optimised, and more. This paper gives practical guidelines for achieving maximum performance on GPUs.
