how to uniformly execute benchmarks on linux
 
Dear Sir/Madam,
I am doing project on adapting Linux for scalable multi core architecture. I am testing Linux's performance with benchmarks. When I am running the benchmarks in the system then other programs like background processes were running in the system. I think system load due to background processes is not fixed, as a result execution time of benchmarks may vary due to system's varying load. Then how to execute benchmarks uniformly. I already searched in net and asked researchers about it but not yet able to find solution of this problem. If possible please try to help me.
thanking you,
regards,
Sachin Agarwalla

What have the phoronix people said about this?

What benchmarks are you running?

What is this "benchmark" software ?
i am only guessing that it is "The Phoronix Test Suite "
http://www.phoronix-test-suite.com/

and WHAT operating systems ?
Linux is just the kernel

answer of query
 
I have ubuntu 12.04 installed on DELL OPTIPLEX 990 model which contains core i5 processor. Benchmarks are forkbench to test process management, mmapbench to test memory management etc. I want to test Linux kernel's different portions performance on multi core through different benchmarks.

Apparently you are just getting started.
Use the phoronix test suite and modify code if required.
Ubuntu kernel is not a vanilla kernel.
