Knowing The Parallel Computer
Was it difficult to
design a MM algorithm without a clear idea of how the processors
interact with the memory?
•To be
effective, programmers and algorithm designers must know the characteristics
of the
computer that will run their algorithms
–Call
this the machine model
–We forget the importance of the machine model because the
sequential model -- von Neumann -- is in our bones … we never think about
it
–Parallelism
needs a different model from vN
