Person of Interest 第五季第一集放出后本宝宝迫不及待的去看了....说实话，这个时刻我等的太久了.....
这里给了个特写，确定了是 PS3 主机无误
然后本宝宝就开始想这个问题：300 台 PS3 主机造超算，这尼玛不是在逗我？
Wikipedia上对 PS3 主机的硬件性能介绍是这样的:
PlayStation 3 features a slot-loading 2x speed Blu-ray Disc drive for games, Blu-ray movies, DVDs, CDs and other optical media. It was originally available with hard drives of 20 and 60 GB (20 GB model was not available in PAL regions) but various sizes up to 500 GB have been made available since then (see: model comparison). All PS3 models have user-upgradeable 2.5" SATA hard drives.
PlayStation 3 uses the Cell microprocessor, designed by Sony, Toshiba and IBM, as its CPU, which is made up of one 3.2 GHz PowerPC-based "Power Processing Element" (PPE) and eight Synergistic Processing Elements (SPEs). The eighth SPE is disabled to improve chip yields. Only six of the seven SPEs are accessible to developers as the seventh SPE is reserved by the console's operating system. Graphics processing is handled by the NVIDIA RSX 'Reality Synthesizer', which can produce resolutions from 480i/576i SD up to 1080p HD. PlayStation 3 has 256 MB of XDR DRAM main memory and 256 MB of GDDR3 video memory for the RSX.
The system has Bluetooth 2.0 (with support for up to 7 Bluetooth devices), Gigabit Ethernet, USB 2.0 and HDMI 1.4[note 1] built in on all currently shipping models. Wi-Fi networking is also built-in on all but the 20 GB models, while a flash card reader (compatible with Memory Stick, SD/MMC and CompactFlash/Microdrive media) is built-in on 60 GB and CECHExx 80 GB models.
从中不难看出 PS3 使用了索尼、东芝、IBM 联合开发的微处理器，拥有 3.2GHz 主频，显卡方面使用 Nvidia 的 RSX，包含同主频的 256MB XDR 3.2GHz 主内存和 256MB GDDR3 650MHz 绘图专用内存
从官方文案中不难看出索尼一心想把超算带入家庭的野心。就在 wikipedia 对 PS3 硬件性能做介绍的上面一个段落，我看到了我需要的内容：
PS3's hardware has also been used to build supercomputers for high-performance computing.Fixstars Solutions sells a version of Yellow Dog Linux for PlayStation 3 (originally sold by Terra Soft Solutions).RapidMind produced a stream programming package for PS3, but were acquired by Intel in 2009. Also, on January 3, 2007, Dr. Frank Mueller, Associate Professor of Computer science at NCSU, clustered 8 PS3s. Mueller commented that the 256 MB of system RAM is a limitation for this particular application and is considering attempting to retrofit more RAM. Software includes: Fedora Core 5 Linux ppc64, MPICH2, OpenMP v 2.5, GNU Compiler Collection and CellSDK 1.1. As a more cost-effective alternative to conventional supercomputers, the U.S. military has purchased clusters of PS3 units for research purposes. Retail PS3 Slim units cannot be used for supercomputing, because PS3 Slim lacks the ability to boot into a third-party OS.
In November 2010 the Air Force Research Laboratory (AFRL) created a powerful supercomputer by connecting together 1,760 Sony PS3s which include 168 separate graphical processing units and 84 coordinating servers in a parallel array capable of performing 500 trillion floating-point operations per second (500 TFLOPS). As built the Condor Cluster was the 33rd largest supercomputer in the world and would be used to analyze high definition satellite imagery.
美国军方购买了 PS3 集群用于科研目的，但是零售版本的 PS3 由于无法引导启动第三方 OS 所以不能用作超算目的。
2010年11月美国空军研究实验室就已经用 1760 台 PS3 搭建出了一个超算平台，而 POI 却只用了 300 台零售版本的 PS3 也做了一个给机器宝宝容纳身子的超算平台
