Linpack+Linux+Power+gcc+IBM ESSL = well.. a Top500 Linpack result
By: Bill Buros. Continuing our theme of leveraging gcc for performance based workloads, here we point to a couple of recent Linpack results from the Top500 web site. The Top500 site tracks the results of Linpack runs from small single standalone servers all of the way up through the Top 500 supercomputers in the world. Naturally, the smaller results are buried in a very big table somewhere on the site, but the Top500 entries are listed separately. What’s noteworthy in the two results below is that "gcc" was leveraged to build... [More]

More gcc news! SAP Sales and Distribution (SD) Standard Application Benchmark published
Last week a new SAP Sales and Distribution (SD) Standard Application Benchmark result was published on the SAP benchmark site ( here ). The result was produced with SLES 11 sp1 running on an IBM Power 730 12-core system. What's particularly cool for us is the result was produced with gcc 4.3.4 as shipped with the SLES 11 distro. For more information on general SAP tunings, an IBM InfoCenter Blueprint paper was published which explains how to tune an SAP implementation on Linux on Power. The article describes common system tunings, as... [More]

gcc performance - getting better all of the time
By: Bill Buros. There's quite a bit going on in the world of Linux on Power, where several of us have some focus on improvements for performance. Lately, a series of articles have been published on DeveloperWorks which nicely highlight the performance gains that gcc (packaged in the Advance Toolchain) provides over the gcc packaged with the Linux operating system. Two articles are available which dive into performance gains across a number of workloads embedded in the SPECcpu2006 suite. The approach is simple. Use gcc as bundled with the... [More]
