Check out Ayakaโ€™s talk on Tuesday afternoon about a performance profiler she made for accelerator design languages. It makes these cycle-count flamegraphs: https://al.radbox.org/doi/10.1145/3839509

Figure 4 from the paper, which is a flamegraph. The caption says:

Flame graph from running Petal on the program in Figure 2. Elements that occur in parallel are normalized relative to the total length, so that summing up all threads result in the total length of the par block. Elements within the s1 cell are omitted for space.

Headed to OOPSLA for burritos and chill hangs! And maybe some programming languages

I was already controlling for performance anomalies related to layout within the executable when evaluating optimization opportunities. But I have a repro where making a byte-exact copy of an executable occasionally (about 10% of the time) will create a program that runs significantly slower [โ€ฆ]

I got a mosquito bite on my eyelid, which is proof that god doesnโ€™t exist

@wingo (and I guess also that there are no aliases)

@adrian.discuss.systems.ap.brid.gyAug 27, 2026, 10:00 PM

what do yโ€™all think the difference between trash and garbage is?

@adrian.discuss.systems.ap.brid.gyAug 27, 2026, 9:25 PM

@wingo just to clarify: what we need to know is that B can never be mutated after the closure definition point, right? (so it suffices to prove that B is dead there, but that is probably too conservative)
