Research, development and operation of scientific computing facilities is essential to accomplish IHEP’s mission. IHEP has been an early adopter of new computing technologies, ever since hosting the first Internet node in China, BEPC2.IHEP.CERN.CH, on a VAX785 at IHEP in 1988. Our computing research continues to develop the frontiers of networking, high performance computing, grid and cloud computing, and high performance storage. 

IHEP’s computing environment provides a data-intensive computing platform with high performance computing and data storage of 10 PB, with 160 Gbps backbone bandwidth for the institute’s intranet and 20 Gbps bandwidth for external internet. A 10 Gbps IPv4 network link and 10 Gbps IPv6 network link IHEP to the global network, with dedicated 10 Gbps high bandwidth network links to Europe and North America. The high performance network provides support for large volume data transfers and international collaborations. 

The network link also guarantees the operation of the grid computing system at IHEP. IHEP provides a Tier-2 site in the Worldwide LHC Computing Grid (WLCG), and more than 2 PB of data have been transferred and processed per year for the ATLAS and CMS experiments. It also acts as a Regional Operations Center (ROC) for the CMS experiment, the first in Asia, allowing round-the-clock monitoring and operations. As well as the LHC experiments, IHEP also provides grid computing services to domestic experiments such as BESIII and JUNO, and other applications such as bioinformatics and geodynamics.

In August 1986, IHEP established the first Internet link in China with CERN, and the first email from China was sent from IHEP to CERN.

In May 1994, with a PC server running a Linux system, IHEP set up the first website in China, giving information about IHEP’s scientific activities and about China generally, as well as linking to important websites in the rest of the world.
