The increasing number of CPU cores makes me worry about the relatively low utilization of the recent manycore CPUs, along with the potential increase in wasted energy, and the low degree of parallelization of many applications submitted to many-core based servers. EXludus CEO Dale Geldart answers a couple of questions.

We are seeing rapid increases in processor core counts, and a great deal of discussion is taking place in the industry concerning the best way to make use of large core count servers. What is eXludus’ view on this topic?

Geldart: We have certainly taken note of the discussion, as our main focus at eXludus is developing solutions that allow for more efficient use of multicore processing power. We are looking at the problem a bit differently than most, though. The majority of discussion and activity on this subject relates to parallelizing applications so that an application may natively tap into the parallel processing capabilities of multicore. While we certainly concur that parallelizing applications can provide benefit, we believe that improving system resource allocations can yield equally large, and possibly larger, benefits. So, it’s the resource allocation side of the problem that we’re addressing, which is a much less discussed side of the problem.
