Linux统治超级计算领域的九个理由

linux unix node.js 开源对象存储

In 1994, the first Beowulf Cluster was built at NASA, using Linux, as an alternative to the very expensive HPC supercomputers. “Beowulf Clusters are scalable performance clusters based on commodity hardware, on a private system network, with open-source software (Linux) infrastructure. The designer can improve performance proportionally with added machines. The commodity hardware can be any of a number of mass-market, stand-alone compute nodes as simple as two networked computers, each running Linux and sharing a file system, or as complex as 1,024 nodes with a high-speed, low-latency network.” 1994年，在NASA,使用Linux建立了第一个Beowulf集群，作为昂贵的HPC超级计算机的一种替代品。 “Beowulf集群是基于商用硬件的可扩展的高性能集群，建立在专用的系统网络和开源软件（Linux）基础设施上。设计者可以通过按比例添加机器来提高性能。硬件可以是简单的只需两台联网计算机组成的计算节点，每个节点都运行Linux,并共享一个文件系统，或复杂的像具有高速，低延迟的1,024节点的网络。“

Clang vs Other Open Source Compilers

Building an entirely new compiler front-end is a big task, and it isn't always clear to people why we decided to do this. Here we compare Clang and its goals to other open source compiler front-ends that are available. We restrict the discussion to very specific objective points to avoid controversy where possible. Also, software is infinitely mutable, so we don't talk about little details that can be fixed with a reasonable amount of effort: we'll talk about issues that are difficult to fix for architectural or political reasons.
