The Institute of Physics Belgrade was founded in 1961 by the government of the Republic of Serbia with a mission to conduct high quality research in the area of physics. At present it contributes more than 10% of the total scientific output of the country. IPB is highly recognized research institute at the EU level, being host to four EU Centers of Excellence: CX-CMCS (Centre of Excellence for Computational Modeling of Complex Systems), OPSA (Centre of Excellence for Optical Spectroscopy Applied in Physics, Material Science and Environmental Protection), IPB-CNP (Reinforcing Experimental Centre for Non-Equilibrium Studies with Application in Nano-Technologies, Etching of Integrated Circuits and Environmental Research), and QUPOM (Reinforcing the Centre for Quantum and Optical Metrology).

In the past, IPB was involved in several e-Infrastructure projects: Grid-related (EGEE-II, EGEE-III, SEE-GRID, SEE-GRID-2, and SEE-GRID-SCI), HPC related (HP-SEE, PRACE-1IP, PRACE-2IP and PRACE-3IP), as well as in research infrastructures projects (agINFRA and SemaGrow). Currently, IPB is partner in the regional e-Infrastructure VI-SEEM project.

In 2008, IPB is designated by the Serbian government as the referent institution for Grid computing and HPC in the country, and appointed to represent Serbia in European HPC-related projects and infrastructures. IPB coordinates the Academic and Education Grid Initiative of Serbia (AEGIS) and all HPC-related activities in Serbia.
