What You Can Buy: Linux Performance

Built around several freely available benchmarks for Linux, Linux-Bench is a project spearheaded by Patrick at ServeTheHome to streamline about a dozen of these tests in a single neat package run via a set of three commands using an Ubuntu 11.04 LiveCD. These tests include fluid dynamics used by NASA, ray-tracing, OpenSSL, molecular modeling, and a scalable data structure server for web deployments. We run Linux-Bench and have chosen to report a select few of the tests that rely on CPU and DRAM speed.

C-Ray: link

C-Ray is a simple ray-tracing program that focuses almost exclusively on processor performance rather than DRAM access. The test in Linux-Bench renders a heavy complex scene offering a large scalable scenario.

NAMD, Scalable Molecular Dynamics: link

Developed by the Theoretical and Computational Biophysics Group at the University of Illinois at Urbana-Champaign, NAMD is a set of parallel molecular dynamics codes for extreme parallelization up to and beyond 200,000 cores. The reference paper detailing NAMD has over 4000 citations, and our testing runs a small simulation where the calculation steps per unit time is the output vector.

NPB, Fluid Dynamics: link

Aside from LINPACK, there are many other ways to benchmark supercomputers in terms of how effective they are for various types of mathematical processes. The NAS Parallel Benchmarks (NPB) are a set of small programs originally designed for NASA to test their supercomputers in terms of fluid dynamics simulations, useful for airflow reactions and design.

Redis: link

Many of the online applications rely on key-value caches and data structure servers to operate. Redis is an open-source, scalable web technology with a b developer base, but also relies heavily on memory bandwidth as well as CPU performance.

    As a Sandy Bridge owner I've been really looking forward to this. Sadly it's a trailer I've been waiting for and now the show has arrived. Great write up as always. Reply

    Wonder if i'll make the upgrade or wait for skylake-E next spring (more likely) Reply

    I'm waiting to see what AMD's Zen brings to the table next year. Reply

    Who knows, maybe they'll catch Nehalem? Reply

    Hey if they catch up to Sandybridge they will won't be too far off the mark to retake the crown apparently! ROFL.... Reply

    In their dreams. The moment that happens, Intel will trot out something actually new and destroy everything again. Reply

    But you wouldn't want that to happen since you love how much Intel are milking their customers right?

    I mean, who the hell cares for the benefits that come from competition...... Silly me.

    Agreed, the second AMD goes under, Intel will announce $1000 'consumer' CPUs, enjoy Intel phanboiz. :P Reply
