I appologize if this is not a question tuned well to this mailing list. I
do however think this is the best place to ask and get a valid answer.
The University of Utah is building it's first linux cluster. We have an
approx $40K budget. Based on this we came up with two designs, a single
processor/node design and a dual processor/node. We have people arguing
against both. These are the major concerns. Two processors will fight
over the memory bandwidth, this is the major concern fighting for single
processors. Two processors allows us a greater learning environment,
basically we can mpi/pvm from machine to machine then use OpenMP to work
with shared memory within a machine. Taking out what we want can someone
give me a reality check hear and tell me why or why I wouldn't want to use
SMP? Thanks in advance.
BTW, our early testing using two dual proceessor PII 450 machines shows
that we do take a big hit when using 2 processors in a machine. But this
test is not using shared memory whithin a machine. Our design will use
single or dual processor PII 350 machines with 256MB of RAM per processor.
