Hi all I would like to submit a new project request and hopefully get a sponsor.
Project Name: HAR (Hardware Activity Reporter) Project Description The goal of this project is to develop a performance monitoring tool that samples hardware counters in the system (primarily cpu counters, but could extend to bus counters) to produce higher-level metrics (eg, mips, flops, cache miss, stall rate, bus utilization) which can guide a bottleneck analysis and performance tuning process. There exists a first release of HAR, developed internally at Sun, that only looks at cpu counters and supports currently only UltraSPARC1-4 (not 4+) & Pentium3 systems. The open-sourcing of the existing HAR code has been approved by Sun. There are a few users of HAR out there that keep asking for newer releases (eg eBay) and support for recent hardware. The purpose of open-sourcing HAR is to provide a proper place for the continued development & dissemination of HAR. The primary task will be to port HAR to Solaris 10 and libcpc2 so Niagara, AMD and modern Intel processors can be supported. Related Projects There are no known related projects or dependencies. HAR will build directly on top of libcpc2 for accessing cpu counters. Access to bus counters has not been researched yet. Current Team We are already 3 engineers working on this subject Cheers, Amir Javanshir This message posted from opensolaris.org
