Beta version 24.12 available
--------------------------------------------------------------------------------
The first beta of version 24.12 can be downloaded from:

Windows: ftp://mersenne.org/gimps/p95v2412.zip
Linux: ftp://mersenne.org/gimps/mprime2412.zip.tar.gz or
Static Linux: ftp://mersenne.org/gimps/sprime2412.zip.tar.gz

This version is faster for all SSE2 machines (2 - 10%).
SSE2 code supports FFT sizes up to 32 million, but don't use them yet. They need some more QA (see next post).
Has a workaround for Error 3 problem.
Should be harder for computers to spontaneously rename themselves.
--------------------------------------------------------------------------------
I'm down to just one idea left to speed up the code. After working on that for a while, I will need volunteers to time prime95 on various L2 cache sizes and I will need volunteers to QA the large FFT sizes.

I especially need an AMD SSE2 machine with 256K L2 cache.

I'll also need a 1MB L2 cache P4 and 512K L2 cache AMD64 machine, but these are very common.

I need an AMD64 and P4 machine with 2GB of memory to QA the large FFTs.

If you can help, please revisit this section of the forums over the next week or two. I'll announce a test version to download for benchmarking and QAing.
--------------------------------------------------------------------------------
这个新版本对支持 SSE2 的机器能有 2 - 10% 的提速。

下载新版本压缩包后，先退出正在运行的 prime95.exe 程序，然后将压缩包内的 prime95.exe 直接解压缩到老版本所在文件夹覆盖原有的 prime95.exe 程序即可完成升级。
