(moderation:
A new Beta Test App is available on our usual Beta Test Page.
It features some more hand-crafted assembler code and a slightly modified (hopefully improved) CPU detection.
I've seen very large variations regarding the speed compared to the 4.01 App depending on the CPU type, so if you report speed values here, please also report the CPU.
Happy tessting!

LINUX Beta Test App 4.16 available
)
Here are some times. The top three are from the new science app (4.16) whereas the rest are from the 4.01 app.
10,433.72
10,112.48
10,129.39
11,911.66
11,483.37
11,483.67
11,478.31
11,625.21
New avg = 10225.20
Old avg = 11596.44
New = 0.882 * old, ie a 11.8% speedup, so far. Nice.
I'm using a P3 coppermine, 600MHz, which supports sse. It has 256 KB cache, and afaik, sse has been successfully detected by both app versions.

why does now the linux-version that already was faster than the windows version get improvements but the windows version doesnt?

We are testing this code on Linux first (this time), but the improvements will go into all x86-based Apps.

Athlon XP 2700+ just finished first wu with 4.16. No problems so far.
4.01 approx. 25,300 sec.
4.16 22,295 sec.
50 minutes faster.
Great work.

After downloading beta test
)
After downloading beta test application 4.16 I got two validate error results. The firt was crunched by original app. The second was crunched by test app.
I crunched about 60 results on this machine and these two results are the only with any problem.
Speed-up is about 11,5% on my Athlon64 (socket 754)
Which is the meaning of
)
Which is the meaning of "small x" in a result report? Does it mean a short WU?

The third result have

The third result have validate error too???
EDIT: All my results (by official app even test app) have blank stderr.txt, is it correct?
