alt Hacker NewsAFAIK, you can't explicitly allocate cache like you allocate RAM however. A bit like if you could only work on files and ram was used for cache. Maybe I am mistaken ? (Edit: typo)

You can't explicitly allocate cache, but you can lay things out in memory to minimize cache misses.

You can in CUDA. You can have shared memory which is basically L1 cache you have full control over. It's called shared memory because all threads within a block (which reside on a common SM) have fast access to it. The downside: you now have less regular L1 cache.
