When it comes to high power computing, Linux has a big advantage,
especially when it comes to 64-bit options. This week starts the first in a
series of reviews on how to break the 32-bit barrier.
The introduction of the Linux 2.6 kernel and operating systems like
SLES9 have given Linux users a robust alternative to SMP: NUMA, the
architecture of choice for AMD64.. The differences are neither transparent
nor trivial. This week openBench Labs tests a quad-Opteron system with a
traditional IA-32 dual-processor SMP system. In the process, we
discover there are still a few nasty issues powering up to 64 bits.
In future issues we'll continue with EM64T Xeon- and Itanium- based
Linux is also at the forefront of an other form of power. At the DOE,
researchers are unraveling the molecular forces that could one day bring
the world a clean source of renewable energy: A mandate that requires a
significant amount of computing power. Learn how Linux is providing
researchers with the scalability they need at a cost they can afford.
