来加拿大读高中吧。

不用藏, 学校鼓励上课以及做作业用电脑。

尽管您只想玩游戏, 加拿大也有培养电玩竟技运动的尖子。

如果真的那么惨, 不如换成二手笔记本。

当然, 赶紧上大学也是个很不错的方法。


另外, 就是不要藏。

让学校知道您有个电脑, 说不定学校还出钱帮您升级呢。


举例

俺有一台 256GB 内存的电脑。





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:


  1. 风扇声音确实有点大,如果只插上一个电源 开机后的几十秒,和半匹~一匹马力的吸尘器差不多。(机器认为是故障,所以风扇不降速)

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:
