Taking advantage of multiple cores

I just got a new computer with an i7 processor ( 4 cores x 2 threads per core). I am now far more aware of the dismal state of user software that is not multi-threaded. Many tasks that I expected to run much faster, are just as slow since they are not able to take advantage of the extra cores.[Read More]

Solaris Performance Primer: Introduction

This blog entry is based on an ISV-Engineering performance code camp for software partners. We are publishing the 30 most important freely available tools and commands to figure why a system isn't scaling in this sequence of blog entries. Be aware: this is more a basic cookbook in a "minute man" style which hopefully helps to solve 80% of the common problems in 10 minutes.The Solaris Performance Primer moved to a new location.

Upcoming partner related activities in and around London

In our first attempt to expand the audience of this column to other parts of Europe, here are two events of particular significance to our partners in and around London for the next month or so:


 

Make it Fly

Thursday 25th October, 8:30 - 1pm
London, Sun City Office

 

Registration: http://www.makeitfly.co.uk/register.php

Dr Clive King and Phil Harman, will be presenting a morning session on Solaris performance, debugging and what is in the latest release of
Solaris 10, and why it is so cool.
Aimed at a technical audience, any partners developing on Solaris would benefit from this session, from two great Solaris minds.

Session 1: Full contact debugging with the Solaris run-time linker!
The run-time linker(ld.so.1) is fundamental to the operation of Solaris, but few use its numerous powerful debugging features. We discuss the run-time linker, what it does, why its a good idea and how you can use it for debugging a number of classes of problems. We also show how it can be used for time travel!

Session 2: The Yin and Yang of /proc
Procfs is a file system that provides access to the state of each process and light-weight process (lwp) in the system. It’s the foundation upon which debuggers like dbx and mdb are built, as well as tools such as ps, pstack and pmap. procfs is a system where you can have correct, but you can't have fast. To get a consistent, correct snapshot of a process state requires the Solaris kernel to do an awful lot of work and it can impact on system performance if used without thought. This session will help you avoid a very common set of problems as well as considering some of the wider issues around system monitoring.

Session 3: Solaris Greater Than the Sum of its Parts
Solaris technologies such as ZFS, DTrace and Zones are pretty amazing in their own right, but it is the combination of such innovations in one platform which make Solaris so much more than "just another commodity operating system".

Session 4: Solaris 10 8/07 - The fourth update of Solaris 10 brings some very important enhancements to this landmark operating system
platform. The focus of this session will be on those parts of Solaris10 8/07 of particular interest to developers.

Update: Solaris Performance ToolsCD 3.0 available online

I got quite some feedback on the performance tool CD. I have been able to make the CD available online for direct download. Allow me to describe it one more time in length as I did in my blog before:


What is it about?
At Sun, for our customers and partners, the Solaris Performance ToolsCD is a well known project of the Frankfurt benchmark center since 1999. This collection of (public domain) tools on a CD enables you to analyze on optimize Sun systems. The tools are used and maintained on a daily basis during our benchmark projects. The CD covers as well many information and links to performance related literature.
This is the fourth release of the ToolsCD with the focus on Solaris 10 support for SPARC and x86/x64 based Sun systems.

The CD covers within 300 MB:

  • dimSTAT v8.1 - collect and analyze performance data

  • Dtrace Tools - Brendan Gregg's collection of Dtrace scripts

  • K9Toolkit - freeware tools written using the KStat library on a Solaris 9

  • sysperfstat - displays utilization and saturation for CPU, memory, disk and network, all on one line.

  • cpuinfo - displays CPU configuration (number, type, clock and strands)

  • meminfo - displays configuration of physical memory and swap devices or files

  • iobar - displays io for disk-devices in a |cpubar|-like fashion

  • iotop - displays |iostat -x| in a |top|-like fashion

  • checkcable - prints the link up status for network interfaces

  • nicstat - prints statistics for the network interfaces such as KBytes/s read and write, Packets/s etc.


The Solaris Performance Tools CD is a best effort compilation which comes with a warranty disclaimer, as there is no guaranteed support for the Tools CD. Tool usage is on ones own risk. Horst Leitner is the chief editor of this CD. He's been compilng the work of the entire performance team. Please let them know if the software is helpful for you.

We can make the tools CD available to our SPA ( Sun Partner Advantage) members. Please send me an email. The CD is available as well as a 250MB gzip tar ball for online download.
