Top 10 Objections to GPU Computing Reconsidered

Jun 09, 2011 | As we approach the four-year release anniversary of NVIDIA CUDA, arguably the ground zero of the GPGPU movement, there are many who have flirted, piloted and adopted the technology, but many more who are sitting on the sidelines for various reasons. In our work, we have come across many of the latter, and have thus compiled a list of the most common questions, concerns and assertions that preempt efforts to evaluate the technology.
