I, and of course you, know the public meaning of "cross section" but I could not understand its meaning in the following sentence: "GPUs offer high computational power but require high scheduling strain to manage parallel processes, which increases the GPU cross section." Could you explain what does "cross section" mean here? Thank you.
cross-section in this cases I think means the amount of memory,power,and bandwidth the GPU is allotted to perform operations in comparison to the total unit of tasks the I/O scheduler is tasked with balancing at a time. The I/O scheduler must analyze all tasks and accordingly multitask operations to maintain a certain lvl of quality performance. GPU utilizes parallel task programming to accelerate the rendering of images.In order to assure effectiveness GPU increases the probability I/O scheduler will prioritize GPU processes. This increases the number of GPU tasks in a faster sequence; increasing the total number of tasks.the I/O scheduler is strained to handle the larger volume efficiently
I think it is confusing because you have the I/O scheduling and the GPU operations fitting (on differnt lvls) a mix of "cross section" definitions: the informal definition:A variety, a diversity; the statistical definition: a sample meant to be representative of a whole;the physics definition: measure of the probability, expressed as the effective area of a given particle interaction/reaction; geometric definition: a cut made into a solid shape/form axis by a line/plane at a 90 degree angle.
As written we should interpret this as "high computation power increases the GPU cross section." I cannot make sense of this.
However, if we assume there was a grammatical or typographical error:
GPUs offer high computational power but require high scheduling strain to manage parallel processes, which increase the GPU cross section.
...then I would interpret the sentence as "parallel processes increase the GPU cross section." This makes a little more sense. It explains why you use a GPU (greater cross section -- greater number of operations built into one) despite the scheduling strain.
