Shared vs
Distributed Programming
nDistributed Memory
qmust use
message passing
mMPI, PVM,
TCGMSG
qscalable to
a large number of processors
qgenerally
more difficult to program
nShared Memory
qcan use
compiler directives (OpenMP)
qcan also use
message passing
qeasier to
program
qlimited
scalability
nDistributed - Shared Memory
