Scaling Compression Performance

The SPARC CMT servers have a real ability to scale under CPU load. The parallel bzip2 utility provides another good example of what such a server can achieve.[Read More]

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]

Monitoring CMT Servers with perfbar version 1.2

Perfbar 1.2 is a very valuable visual tool which allows to detect bottle necks on massive parallel SMP servers like the T5000 class of servers.[Read More]

Performance on SPARC CMT Servers

Dear partners, Glenn Fawcett, one of our leading engineers is starting a performance series for throughput computing on his blog.

This is an outline of what he plans to publish:

  • Overview
    • Definition of Throughput computing, multi-threading, and concurrency.
    • Examples of benchmarks that of show application throughput.
  • Explore system parallelism
    • Unix commands and parallel options
    • Concurrent builds/compiles.
    • Configuring the system for parallelism
  • Configuring applications for parallelism
    • Concurrency vs multi-threading
    • Single-Threaded jobs
  • Database parallelism with Oracle
    • Parallel loader and datapump
    • Index build parallelism
    • Concurrent processing in Oracle
    • Configuring Oracle for CMT server

He is discussing all the key topics partners have to deal with in order to scale up their applications.
