Shared Memory and Cache Benchmark

[Curtor]

Hello there,

I know that there are a plethora of RAM benchmarking suites out there, but I am looking for one that does more than simply tells you the speed/throughput/etc. of the RAM itself.

Is there a good tool anyone recommends to benchmark the following?

- generic main memory performance
- L1 & L2 cache performance
- shared memory performance
(L1 & L2 usage while 2 programs with shared memory smash the same or different area in memory, while locked on the same or on different cores)

Thanks!

In fact, what is a good benchmarking tool just for RAM?
MemTest simply tests if your RAM is working, but what about performance wise?
I've considered creating a RAM disk and running a tool like Bonnie.
Any suggestions or comments?

The best linux testing site on the net. I believe that they allow you to download their test suite.
Bandwidth: a memory bandwidth benchmark is another I found. I didn't investigate it, so don't know if it's for linux. Just checked-it's for 64bit linux.
