AMD FX-8150 With The Open64 5.0 Compiler

The Open64 5.0 compiler was released earlier this month with many changes, among the prominently noted items were greater optimizations for AMD's Bulldozer CPUs. In this article is a first-look at the Open64 5.0 compiler performance compared to its earlier release, as tested on an AMD FX-8150 eight-core "Bulldozer" processor.

AMD Bulldozer "bdver1" Compiler Performance

It is time for another round of compiler benchmarks on AMD's latest FX-8150 Bulldozer processor. In this article is comparing the GCC 4.6.1, GCC 4.7 development, Open64 4.2.4, and AMD Open64 4.2.5.2 compilers in their stock configuration, when the binaries are built again but with the march/mtune flags set to "bdver1", and a third when being built with the "bdver1" architecture and tuning flags along with "-Ofast" for the highest-level of compiler optimizations.

A Proper Solution To The Linux ASPM Problem

At long last, it looks like there is an adequate solution to the Active State Power Management (ASPM) problem in the Linux kernel , a.k.a. the well-known and wide-spread power regression in the Linux 2.6.38 kernel, which has been causing many laptops to go through significantly more power than they should. This is not another workaround, but rather a behavioral change in the kernel to better decide when the PCI Express ASPM support should be toggled.

GCC 4.6, LLVM/Clang 3.0, Open64 Benchmarks

For those interested by last week's articles on the AMD Bulldozer benchmarks of the GCC, Open64, and LLVM/Clang compilers and the FX-8150 compiler tuning, but curious to know how the new LLVM/Clang 3.0 and other compilers perform on other processors, here's some new test results. These tests are looking at GCC 4.6, LLVM/Clang 3.0-RC1, and AMD Open64 compilers on Intel Sandy Bridge and AMD Shanghai hardware.

Ubuntu 11.10: Xen vs. KVM vs. VirtualBox

While last week I showed how Ubuntu's performance has evolved as a KVM guest from Ubuntu 8.04 through Ubuntu 11.10, in today's article is a Linux virtualization showdown between VirtualBox, Xen, and KVM while using Ubuntu 11.10 on the Linux 3.0 kernel.
