是的, 俺收集了不少垃圾。
包括这台 256 GB 内存, 带冗余电源的铁疙瘩。
俺也知道, 这种收藏癖得治!
下面是关于这台电脑的散文。
话说 1996 年的时候, 俺就用过内存 256MB 以上的电脑, 从那时起就对内存有了一种畸恋 (Fetishism).
最近报完税了,兜里还剩点零花钱,思量着买个电脑来玩玩。最后看上了带 256GB 内存 (32x8GB)+ 24核CPU (4X6c) 的Dell PowerEdge R900 .
经过漫长的等待, 冰天雪地的早上, 终于到货了。 快递公司的司机问, 这纸盒里面啥玩意那么重, 差不多 100 磅了, 不会是尸体吧?俺说是俺的二手电脑。运费 300 多刀。
俺手无缚鸡之力, 一个人根本抬不起来。 用滚的办法, 一路将箱子滚到了地下室, 再用滚动的办法把开了箱的电脑滚上了架子。
上个玩家在里面装了个 Windows 2012 Server 评估版, 俺觉得碍眼就用 Fedora 把它替代了。
如图:
。
分享一点经验:
2. 如果插上两个电源, 正常运行的时候, 风扇声音会下降很多很多。 如图:
。
3. 32 条 8GB 内存, 在运输过程中可能会松脱, 松脱的话黄灯会亮。
4. 软起动, 例如 reboot , 不会再发出喷气机般的巨响。
5. 耗电量明天再测。
** 用 X FORWARDING 不用跑到地下室吸土
俺打算用这个电脑来仿真耳机以及电路, 而且这个电脑还不够一个 Sennheiser HD800 贵。
您信吗? 俺信了, 而且买回家了。

当然, 这是俺 DIY 家庭微型集群的第一步。
贝奥武夫机群(Beowulf cluster),又称贝奥伍尔夫集群,是一种高性能的并行计算机集群结构,特点是使用廉价的个人电脑硬件组装以达到最优的性能/价格比。得名于古英语著名史诗《贝奥武夫》。于1994年最早在NASA为Donald Becker等人开发,是目前科学计算中流行的一类并行计算机。最常见的方式是把相同个人电脑作为组装单元,运行Linux或BSD系统。各个单元之间通过小型TCP/IP局域网和有关的程序库来分配计算任务和通信。常用的并行程序库包括MPI和PVM。

运行了一夜,没有什么问题出现。每一条ECC内存似乎都是好的:

题外话:
更新一下,我要来辟谣,这些东西真的其实不怎么占地方,真的受宠若惊,好多点赞我惊了
我是这么摞起来的,然后找个地方,例如床底下,扔进去就好了!!
现在我有80多台电脑了......
就聊聊我桌子上的这四台台式机吧。。我的答案一般有很强的时效性,这个答案是2020年6月22日写的,请注意。。
一台G4 Cube,噪音小,速度可以接受,占地不大。
工具电脑,整体花了180
拿来采集用的,还兼备拨号上网服务器的功能,插了三个猫
桌子下面有一台MDD,一台ThinkStation:
MDD的基本配置是
跑苹果系统速度很快!
ThinkStation就比较有意思了,之前弄来的准系统,可诠释暴力美学,主力机
桌子上腾出了一片空间给笔记本电脑。。
目前桌子上除去四台电脑,有两套网络
看看线是怎么走的:
预留了采集卡的VGA,电话线(拨号上网),网线,四种电源插头给笔记本电脑用
