Sun provides the /usr/local/bin/corestat CLI tool for
their CMT (T1 and T2 Ultrasparc) machines which outputs in a loop with
a line per core, however the output isn't suitable for long-term
monitoring and trending.
Here's my approach to monitoring core (really vcpu or hardware thread) usage, divided into usr and sys. Add
exec vcpuidl /bin/sh /etc/snmp/conf/vcpuidl.sh to /etc/snmp/conf/snmpd.conf and the script /etc/snmp/conf/vcpuidl.sh is simply (mpstat is what corestat calls):

 We are delighted to announce that University of Sao Paulo, Brazil is now the first OpenSPARC Center of Excellence in the Latin America. USP is one of the largest institutions of higher education in Brazil and boasts 75,000 enrolled students.
OpenSPARC team has been working closely with the faculty and students of Pervasive Computing and High Performance Group (PAD) and the Department of Electronic Systems Engineering at the USP which has been actively involved in the research in the areas of reconfigurable computing, transactional cache models, and functional verification.
It's great to see multi-core related research and course-work being developed using the OpenSPARC technology in one of the top schools in Latin America.

As part of JesperFrimann’s challenge with respect to the options available to a company with two aging p690s running Sybase, he suggested that:
It’s 256 threads per box on the T5440 versus 16 on the
p550, and furthermore the power 550 supports shared pool
virtualization.. so it will allow for a much higher utilization. So the
price performance for the p550 wil be far superior to the T5440 IMHO.
So today’s question is: is this true?

The book is intended to act as an indispensable guide and easily accessible resource for academics and hardware developers working on next generation OpenSPARC design projects. |

Kudos to Steve Gillmor for suggesting the site, Sun.com/ponytail in his recent video. We've now activated the site.
Since Steve is so concerned about Sun's open source activities we've aimed this url site at the site that gives an overview of all Sun's open source efforts.
That said, we do appreciate the traffic and as always continue to be dazzled by Steve's rapier wit.
