Alternative Middle Communication
•A
“lighter weight” approach is the one-sided communication,
shmem
•Two
operations are supported --
get(P.loc,mine); -- read directly from loc of proc. P
into mine
put(mine,P.loc,); -- store mine directly into loc
of proc P
•Not
shared memory since there is no memory coherence -- the programmer is responsible
for
keeping the memory sensible
