Enquiry regarding load_kernel

[mckhang]

Hello Dr. Zhao, I was studying your paper and the code shared on the page but had difficulty understanding the "load_kernel()" and "f(block=...., grid=(...., args=[..., stream=...)" parts in subtraction/subtraction2/aggregate functions. How do they affect the subtraction relation function and aggregation function and will the results differ without them?

Any help would be appreciated. Thank you
