optimized applications

Quote:

So, here it is 5 months later. Any opti apps for Windows yet? I have an older laptop that can do SSE calcs. I like to contribute as much as possible to science, thus the need for speed. Someone mentioned a helper app that sizes up a CPUs capabilities, and gives the app that fills the bill to the WUs. If that's true, maybe there's nothing I can do to improve on the stock app I downloaded from E@H. Can somebody clear this up for me?

Thanks,

Steve

The current S5R5 'hierarchical' search application actually consists of three different programs, called einstein_S5R5_3.05_windows_intelx86_n, where:

n=0: no processor optimisation, should run on any x86 processor
n=1: uses SSE code, so probably right for you
n=2: uses SSE2 code

There's a tiny loader program, which checks the CPU capabilities and invokes what it thinks is the right main program for your system. You can use Task Manager to check that it's made the right choice.

In addition, the S5R5 applications all include algorithmic optimisations developed over the years, most notably by Akos Fekete, who started here as a volunteer like you or I but was hired by the project because of his skills in this area. You can see his credit on the contributors page.

The ABP1 Pulsar Search application is not yet so mature, but was further optimised with the release of the x.09 variants some three weeks ago. There's a note on future plans in this direction in the science area.
