AMD's Zen 3 and Intel's Tiger Lake architecture. Supported software Operating systems The Loongson processors are mainly designed around using the Linux operating system. Any operating system supporting the MIPS architecture should theoretically work. Windows CE was ported to a Loongson-based system with minimal effort. In 2010, Lemote ported an Android distribution to the Loongson platform. Loongson machines are used in the package-building and CI infrastructure of Debian and Golang, respectively. This is partially because of Loongson's status as the only vendor producing application-grade MIPS CPUs for retail. As of February 2022, there are 3 Chinese Linux distributions that support LoongArch: these are Kylin, Loongnix and Unity Operating System. There are efforts to build LoongArch support into community versions of Linux. Compiler support The GNU Compiler Collection (GCC) is the main compiler for software development on the Loongson platform. Before 2021 LLVM support was still inadequate due to missing workarounds for Loongson's CPU errata on MIPS. ICT also ported Open64 to the Loongson II platform. LoongArch is supported by the GCC, LLVM, Golang compilers, and supports the Java, JavaScript and .NET virtual machines. Loongson microprocessor specifications Loongson-based systems In 2012 it was reported that Loongson processors had found itself into very few computing systems. The processors are mainly used in Chinese computers; in 2021 it was reported that Loongson supplies CPUs for most desktop computers procured by the Chinese government, and 80% of the Chinese government's servers. The release of the 3A3000 processor in 2015 was noted as turning point for the company's fortunes. In 2017 it was noted that the company's processors were being used in the Beidou satellite. Personal computers In March 2006, a €100 Loongson II computer design called Longmeng (Dragon Dream) was announced by Lemote. In June 2006 at Computex'2006, YellowSheepRiver announced the Municator YSR-639, a small form factor computer based on the 400 MHz Loongson 2. the new 8.9" netbook from the Chinese manufacturer Lemote that replaced mengloong, Yeeloong (Portable Dragon), running Debian, is available in Europe from the Dutch company Tekmote Electronics. In January 2010, Jiangsu province planned to buy 1.5 million Loongson PCs. In September 2011, Lemote announced the Yeeloong-8133 13.3" laptop featuring 900 MHz, quad-core Loongson-3A/2GQ CPU. Supercomputers On 26 December 2007, China revealed its first Loongson based supercomputer in Hefei. The KD-50-I has a reported peak performance of 1 TFLOPS, and about 350 GFLOPS measured by LINPACK. This supercomputer was designed
