People generally aren’t rolling their own matmuls or joins or whatever in production code. There are tons of tools like Numba, Jax, Triton, etc that you can use to write very fast code for new, novel, and unsolved problems. The idea that “if you need fast code, don’t write Python” has been totally obsolete for over a decade.
- fooker 9mo agoYes, that's what I said. If you are writing performance sensitive code that is not covered by a popular Python library, don't do it unless you are a megacorp that can put a team to write and maintain a library.
- oivey 9mo agoIt isn’t what you said. If you want, you can write your own matmul in Numba and it will be roughly as fast as similar C code. You shouldn’t, of course, for the same reason handrolling your own matmuls in C is stupid. Many problems can performantly solved in pure Python, especially via the growing set of tools like the JIT libraries I cited. Even more will be solvable when things like free threaded Python land. It will be a minority of problems that can’t be, if it isn’t already.
