对于并行 Erlang 计算，是否有 Xeon/Opteron 等多核 CPU 的替代方案？
免责声明：作者已尽力提出一个不会像之前那样被关闭的问题 一个。
我编写了一款 Erlang 软件，它已被证明：
- 比它的非平行对应方；
- 在具有更多内核的处理器上很好地扩展。
我想知道是否有比昂贵的至强/皓龙更便宜的替代品。
我想要一个多核 CPU，它：
- 具有比 Xeon 或 Opteron 处理器更多的内核/线程；
- 可以有比 Xeon 或 Opteron 更低的频率（500 MHz 就可以了，Erlang 应用程序不进行任何数字运算）；
- 可以在 Linux/Erlang 上运行；
- 比 Xeon 或 Opteron 处理器便宜。
我找到了这个列表，但也许已经有一些最佳实践用于 Erlang 并行计算的核心 CPU。
Disclaimer: the author has tried his best to ask a question that will not be closed like the previous one.
I have written a piece of Erlang software, that has proven:
- to be N times faster than its non-parallel counterpart;
- to scale nice on processors with more cores.
I would like to know if there is a cheaper alternative to rather expensive Xeon/Opteron.
I would like to have a multi-core CPU, which:
- has more cores/threads than Xeon or Opteron processors;
- can have lower frequency, than Xeon or Opteron (500 MHz is ok, the Erlang application doesn't do any number crunching);
- is possible Linux/Erlang to be run on;
- is cheaper that Xeon or Opteron processor.
I have found this list, but maybe there are already some best practices on which multi-core CPUs to use for Erlang parallel computing.

Niagra 芯片（现在的 Oracle，以前的 Sun）在我 6 年前使用时给我留下了深刻的印象。但它并没有真正节省任何成本。 T-1000（现在称为 Ultra T1）的价格和性能与当时相同价位的基于 2Ghz 四核 Opteron 的戴尔服务器大致相同。
对于您正在寻找的处理器来说，300 美元并不贵。考虑到 CPU 的功能有多强大，它们并不昂贵。 CPU的性价比一直处于相对较低的水平。
如果您的预算确实有限，您总是可以以新设备价格的一小部分购买较旧的较慢设备。租赁结束后的设备通常非常便宜。
The Niagra chip ( now Oracle, formally Sun ) was quite impressive when I used it 6 years ago. But it didn't really introduce any cost savings. A T-1000 ( now called a Ultra T1 ) was about the same price and performance as a 2Ghz Quad Core Opteron based Dell server at the same price point at the time.
$300 US isn't expensive for the processors you are looking at. CPUs aren't expensive considering how powerful they are. CPU price to performance ratios are at an all time low comparatively.
You can always pick up older slower equipment at fractions of the price of new equipment if you really are on a constricted budget. Equipment coming off lease is usually dirt cheap.
