[Beowulf] microbenchmark probes

Hi folks:

  We are tracing and characterizing some performance issues for a 
customer, and I would like to use some microbenchmarks to beat on 
various aspects of the system.   We used stream to identify one aspect 
of a difference, and now we wanted to use other tools as well to get a 
finer grain set of tests.  Previously we used lmbench, but the new 
version has a dependency upon bk, which we don't have.

   Are there any specific tools out there that you might recommend to 
beat on/measure performance (latency/bandwidth) of a) cache, b) tlb, c) 
main memory?  Thanks.

Joe
