simulator for vector processor

mahmood...@gmail.com (Mahmood Naderan) — Fri, 25 Sep 2009 06:23:47 UT

Hi,
I searched but found no simulator for vector processors. For example
virtutech has a lot of targets and platforms but nothing is available
for vector platforms such as cray, NEC SX and ...

Anybody can help?

simulators that could run mpi benchmarks.

hi, all,

do you know any simulators that could run MPI benchmarks ? i'm doing
some architecture research, it's very important for me...

i've tried m5, but it's tough and hard to use...

do you have any good ideas, hints or tips ?

Another conceptual level question regarding to the multi-core processor.
Obviously the multiprocessor core will need much higher bandwidh than the
conventional single one.
E.g. Sun T1 got 25.6GB (1.2 GHZ) nd Pentium got 6.4 GB(3.2 GHZ).
I am just wondering whether the power gain get from the processor will be

RAS = Return Address Stack. It is used to predict the targets of
return instructions.
A SMT processor normally fetches instructions in a round-robin way
from all ready threads. Those N threads are typically different. (Your
assumption is not true in most cases). So the wrongly fetched
instructions are only 1/N of that in the single thread case.

Thanks Navy Ant. Two further thoughts & questions:
a. What do you mean by RAS,
b. For the second fact the SMT got less wrong path fetched,I am not sure
how I understand it correctly. But I can make a stupid example. If I got 8
thread(e.g. assume it exactly the same), it will fetch 8N wrong
instructions. However, in a 8-thread processor, if i ignore the pipelien

From the context, a shared branch predictor is assumed. Power 5 uses a
shared one (only RAS is separate), for example. I would assume
normally a SMT processor uses shared predictor.

I found the following paraph is hard to understand.
*The following results are seen from a simulation study of five
floating-point benchmarks and two integer benchmarks from the SPEC92 suite.
The branch misprediction rate nearly doubles from 5% to 9.1% going from 1
thread to 8 threads in an SMT processor. However, the wrong-path
