The Chaotic State of GPU Programming

As we continue to develop more powerful programs, the demand for GPUs is expected to increase. However, programming with GPUs is still a complicated affair, with several frameworks available that are sometimes locked to specific platforms and often impractical to use. … Despite their widespread use, programming GPUs remains a complex process. Specialized frameworks are needed to write code because conventional programming languages typically lack support for GPUs. Writing code for GPUs is also more counterintuitive than writing sequential programs. You need to account for the GPU’s memory hierarchy and manually balance the computations across the cores to use the GPU efficiently. In the current GPU programming ecosystem, there are several prominent graphics APIs. ... Improving cross-platform support could help developers use GPUs more efficiently. Several frameworks are locked to specific devices and operating systems, which forces developers to reimplement their algorithms. Cross-platform frameworks like WebGPU could help avoid these situations. Another interesting innovation is the integration of accelerated operations into regular code. This can make the programs more efficient and easier to maintain.
