今天分解完成。

用了readyu提供的avx版本gnfs-lasieve4I14e.exe，分解速度提高了1倍，达到0.11 sec/rel。
在产生足够的关系式后，msieve 1.52 svn939产生错误，说矩阵不是可逆的。
后来换了一个msieve，最终成功解析矩阵。

提供一下实际分解经验，大概300-400个核（超算平台），2-3天分解一个512的数

ggnfs-svn413-win64-core2  和 msieve152_svn939_win64_i7  今天早上开始分解 1024 的rsa 不知道多久，反正电脑天天开，2年内分解出来，就应该能用上，2年之后的话，就没有意义了，（电脑配置 I5 3210  12G
内存 win7 64 位）  西天取经去了！

gnfs-lasieve4I14e.exe 在哪里下载，最近也需要分解一个154-digit input ,谢谢分享！！！

http://gilchrist.ca/jeff/factoring/index.html

下载前面2个文件。发现第3个文件下载不了。
CYGWIN  或  Brian Gladman's factmsieve.py   这2个的其中一个都下不了。

那个好心人，上传一下这个第3个文件？谢谢了。。

附件含 factmsieve.py 的两个版本：
1) version 0.83
2) use mpi for the Linear Algebra stage of msieve

谢谢MistHill,下载试试看，

I7 16G内存分解一个154-digit  需要多长时间？

从#4楼的log看，大概是25天。这也只是个参考，具体的分解可能差异较大。
但请注意，楼主用了 readyu 的 AVX 版本，速度提高了1倍！

Intel Core i7/i5/i3 的 Sandy Bridge (E)， Ivy Bridge (E)， Haswell (E)，Broadwell (E) 支持 AVX 扩展。
Haswell (E)，Broadwell (E) 还支持 AVX2。

@MistHill readyu 的 AVX 版本这个版本哪里可以下载到

猜想是 readyu 编译的，可向 readyu 或楼主寻求帮助；也可尝试自己编译。

你所说的应该是yafu-1.34 这个版本的吧  但是具体怎么用不会...

看帖仔细一点。

用了readyu提供的avx版本gnfs-lasieve4I14e.exe，分解速度提高了1倍，达到0.11 sec/rel。

你分解RSA512的时候 第一步用了多长时间？

出现这个问题是哪里的问题 求解

我去年用一台16核（超线程32核）至强E7处理器的服务器，31个核跑，6天解了一个rsa512。

我倒，如果放到国家的天河，1024都是个渣了，看样子已经没什么安全的东西了

不知可否写一个 详细的过程，造福后来者~

保存，留着慢慢学习
