I see heavy optimization going on.
I have not time to see how much of memory copy is in app,but would not be good to SSE(2) it as well?I think about implementation like in VLC media player...(code is however in GPL,so only inspiration most probably :-|)


I don't think that there's much copying done in the App, apart from the first ~1min after startup when setting up the memory structures, reading the data files etc.

And how long it will take to see current optimization in Win appp?


The prefetching is not new at all, it's already used in the MacOS and Windows (Beta & Power) Apps.

As for the advantage of the SSE2 over the SSE version I first need to find out where it comes from, further measurements will depend on this.

With some recent developments around BOINC I'll have another try on compiling the "science App" for Windows with gcc, too, so we can focus on a single compiler (yes, I'm aware of icc, but using that is even more difficult with our current code).

I suddenly get a lot of errors.
Host is a root server hosted at a provider running E@H as a kind of burn in test.

App is the SSE2 version.

Hm. Nothing special about these tasks. The machine still occasionally delivers succesfull and valid results, and the other tasks of the same workunits where your machine throws the errors have been completed successfully, too. Looks like a transient problem on the machine, e.g. temperature related. Weren't this the hottest days of the year so far? Well, that sounds like what a "burn in" test is done for, isn't it?
