Peking University and the Sunflower Technical Project group developed and released to the public the first portable operating system with NT kernel, called Sunflower portable intelligent operating system with cloud (with one Chinese Version and one English version). This technology can mobilize any software and is compatible with any Windows driver. The technology is convenient for Windows users because its unique functions complement those that Windows does not have:

1. The system can carry all softwares, programs, drivers, and systems that run under Windows. After installing, the portable plug-and-play Sunflower system can be used anywhere. It is compatible with any local system, and can be seamlessly integrated with Windows. In addition to being intelligent, lightweight, and quick-start, the system has a comparative running speed with local software and system. Moreover, the system is immunized against virus.

2. Sunflower has a large number of professional versions. Approximately 6,000 softwares for 20 industries are pre-installed in the system. After downloading, users can use this system anywhere.

3. Users can finish tasks through the powerful online operating system and other online programs available with a simple click of the mouse.

4. Users can gather in the Suncloud cloud network to achieve fast search, rapid download, and lightning chats, and set own radio stations. We call for users to share resources and get to know each other, and strive to build a platform where everyone can find anything and anybody they are looking for.

5. It supports the use of a system to manage a large number of devices, both synchronous and rapid deployment of the software and platform, and the virtualization of an enterprise.

6. The equipped Sunflower intelligent programming tool successfully makes the programming process foolproof.

      “My colleague recommended this Sunflower Key for me and asked me to give some comments. Well, it is rely a very good portable platform with lots of apps integrated and installed. Some features like external protection or fast cloud FTP are quite impressive (of course faster than common cloud storage websites). But the most attractive thing to me is their spirit of science. My colleagues in Peking University are doing something scientific instead of business. Software is free, super computers are free, VPNs are free, add-on apps are free, so as the online system (which even contains SciLab!). I can forsee that in future we can live as part of the net of things, under a cloud of science.”

    • No Worry about Virus

      No matter how carefully one uses the computer, they are still exposed to online threats and malware attacks, so the importance of having a correctly-configured antivirus solution should not be underestimated. However, in case the infection has already reached the PC and the security software has been neutralized, there is one more tool that can be tested: Sunflower Mobilesystem with Cloud. In most cases, when the virus is already on the target PC, there is nothing much one can do because the malware typically does not allow users to install or update any antivirus software. Sunflower’s tool on the other hand has taken some protective measures: it can be run on infected computers, even in Safe Mode, and it can automatically remove viruses, Trojans, rootkits, adware or spyware.

    • How fast is our super computer clusters

      A supercomputer is a computer at the frontline of current processing capacity, particularly speed of calculation. Supercomputers were introduced in the 1960s and were designed primarily by Seymour Cray at Control Data Corporation (CDC), and later at Cray Research. While the supercomputers of the 1970s used only a few processors, in the 1990s, machines with thousands of processors began to appear and by the end of the 20th century, massively parallel supercomputers with tens of thousands of "off-the-shelf" processors were the norm. The Peking University cluster runs over 1,000 processors using normal data center air conditioning, grouped in 72 racks/cabinets connected by a high-speed, optical network. A weather forcasting model which takes 5 hours to run on IBM T61 now needs 3 minutes only. Why not try? it's free now!
