HPC group researchs on improving the efficiency of high-performance computing systems. To that end, it is necessary to take different approaches that require a certain level of cooperation and integration: microarchitecture and multiprocessor architecture, compilers, operating systems, analysis, visualization and prediction tools, alg orithms and applications. When measuring efficiency, and besides the classical approach that includes the execution time, we will use metrics that consider design aspec ts (such as cycle time, area and power dissipation of the processor and memory hierarchy, scalability of the microarchitecture and multiprocessor organization), systems correctness, portability and easy-to-use of the programming models and performance when running on multiuser, multiprogrammed and distributed environments, among others.
This group started its formation 33 years ago. The original group was formed by three people, being one of them a doctor and the other two full time lecturers in their first year. The School of Computer Science of Barcelona (FIB) began to have undergraduate students and, therefore, additional assistant lectu rers were be hired. The group kept growing steadily.
The first doctoral thesis developed in the group was presented in 1983. Since then, 151 doctoral theses have been defended, all of them in the area of High Performance Computing. Some of these doctors left our group either to go to industry or to establish research groups in other universities. The rest of the doctors are professors or assistant professors in our department. A few of the first doctors established other l ines of research, fundamentally in the field of computer networking. In the last few years some of the doctors formed in the group have been incorporated into top compa nies in our area. The National Supercomputing Center - Barcelona Supercomputing Center (CNS-BSC) has also hired doctors formed in our group.
