05:31 <mattip> cfbolz: any idea why hypothesis is slow to generate examplars on the new tests for rpython/tool/algo/test/test_graphlib.py?

05:33 <cfbolz> mattip: ah, didn't get that locally

05:33 <cfbolz> Can reduce the size

05:34 <mattip> cool

05:38 <mattip> arigato: sorry about the mails, that was me before I made https://github.com/pypy/binary-testing public

05:39 <mattip> as a private repo it had limited CI resource, now it is public and is less limited

14:45 <mattip> 3 hr 15 min?

14:45 <cfbolz> mattip: does that work for you? Would be great for me

14:46 <mattip> sure

14:51 <Joannah> Vectorization has always made sense for JIT but several research has developed vectorized marking and copying algorithms, I wonder if experimenting with a vector-mode GC for RPython is possible or makes sense.

15:12 <mattip> Joannah: are there structures that preserve locality of the data so that the scatter-gather does not cross cache lines?

15:46 <Joannah> In the old days, I think it required many work arounds, but now I think its possible without too much improvising.

18:41 <Joannah> Thanks all, I will figure out the algorithms that best suite our case (PyPy), but for academic reasons(advisor-alert!!), I will write a proposal first. I can share it if anyone is interested, for a reality check.
