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.

Supercomputer maker Cray has posted a modest loss for the first quarter of 2011 and downgraded its low-end revenue expectations for the year by $20 million. In a conference call with investors, Cray CEO Peter Ungaro blamed most of this on a slowdown in government funding, as countries retreat from the spending spree of the last couple of years. Despite that, Ungaro and company are still aiming for a profitable year as they prepare to roll out new supercomputer offerings in the second half of 2011.
