Performance Evaluation Laboratory

The Performance Evaluation Research Laboratory (PERL for short) has been studying the performance of the computer systems in terms of software and hardware interactions.

Our current major research projects are as follows:

We have proposed a new, generative instruction behavior model for the multiprocessor environment. In order to validate the proposed model on a real computer systems, we have been trying to generate instruction traces in both priviledged and non-priviledged states of the IBM AIX operating system running in the PowerPC architecutre. We have purchased the PowerPC Virtual System to generate traces. We have successfully generated a trace of a SPEC benchmark. The next step is to instrucment the AIX and generate traces of both application programs and the operating system, i.e., the AIX, simultaneously.
