University of Heidelberg, more specifically the Institute for Computer Engineering (ZITI), dedicates its research and teaching activities to the understanding and implementation of complex systems in information technology. UHEI has a profound expert knowledge in the area of design space analysis, hardware design of interconnection networks, and software driver development, especially for the construction of large computing clusters. All levels of system design are covered, starting at the application programming interface, e.g. MPI, through the efficient design of device drivers finishing at custom build hardware devices based on standard cells (ASICs) and FPGAs.


In the DEEP-EST project, the Computer Architecture Group of UHEI worked on improving the memory hierarchy by extending the capabilities and software stack of the Network Attached Memory (NAM) concept first introduced by UHEI in DEEP-ER. A second prototype, the Global Collective Engine (GCE) was developed and attached to the EXTOLL network in order to speed up MPI collective operations and reduce inter-node communication.
