چکیده |
In present study, in order to improve the
performance and reduce the amount of power which is
dissipated in heterogeneous multicore processors, the
ability of detecting the program execution phases is
investigated. The program’s execution intervals have
been classified in different phases based on their
throughput and the utilization of the cores. The results
of implementing the phase detection technique are
investigated on a single core processor and also on a
multi-core processor. To minimize the profiling
overhead, an algorithm for the dynamic adjustment of
the profiling intervals is presented. It is based on the
behavior of the program and reduces the profiling
overhead more than three fold. The results are
obtained from executing multiprocessor benchmarks
on a given processor. In order to show the program
phases clearly, throughput and utilization of execution
intervals are presented on a scatter plot. The results
are presented for both fixed and variable intervals. |
