GPU Backend: Find 0xCAFFEE with π-WAM (Was: ANN: Dogelog Player 2.2.4 (Parallel π-WAM))

Show all headers | View raw

Hi,

We recently got a little excited seeing the
figures of a budget AI laptop experiment running
π-WAM on its silicon integrated GPU. Meanwhile
we could contain ourselves, and brought the
prototype into production via the library(edge/
furryhaze). A first experience report.

We try to find 0xCAFFEE in enumerating 4 6-bit
digits and the baseline is Dogelog Player VM in
a browser. The CPU backend with 64 logical threads
is already 20 times faster, partly due to its
32-bit specialization. The GPU backend with 4096
logical threads boosts a further factor of 7 times.

Bye
