hackerfoolitghost: The good news is that I can throw away some code. The bad news is that there isn't really anything I can think of to make the lookahead faster than 100k paths/sec, so it's not going to get any faster unless it explores less paths.01:23
hackerfooThe SimpleCache doesn't work, and vtr::hash_combine is fast enough.01:24
hackerfooI tried robin_hood::unordered_map, which claims to be faster, and that didn't help either. I think it's just limited by cache misses.01:25
hackerfooAnd it slows down to 70k paths/sec for the full 50T, so it may be even slower for larger graphs.01:28

mithrolitghost: Can you updated acomodi on the new kokoro CI for the SymbiFlow/vtr-verilog-to-routing ?05:01
mithroacomodi: We have added the VtR reg tests and VtR+SymbiFlow as kokoro tests on SymbiFlow/vtr-verilog-to-routing -- should make it easier + faster to check things are not broken05:02
