Emulating ADA RendezVous in π-WAM (Re: GPU Backend: Find 0xCAFFEE with π-WAM)

Show all headers | View raw

Hi,

While ADA RendezVous is often depicted as
tied to a leading task that initiate the
exchange and responder task that completes
the exchange. The exchange mechanism itself
can be extracted into a channel object. We do
so using busy-wait in 100% Prolog to
extend the π-WAM emulator.

To obtain channel objects, we could straight
forward realize the offer/poll from Doug Lea’s
SynchronousQueue using the Prolog dynamic
database. The test case with emulated MPMC
queues worked like a charm. We plan further
benchmarking of physically grouped logical threads.

Bye
