Biography
Brief Biography Description
Juan Carlos Díaz Martín was born in Madrid (Spain) on April 11, 1964. He received the Computer Science "licenciatura" and the Ph.D. in Computer Science from the Politechnique University of Madrid, in 1988 and 1993 respectively.
He is currently an Professor at the Department of Computer and Communication Technology of University of Extremadura in Cáceres (Spain), where he teaches distributed and multicore programming, real-time systems and operating system design. His research interest is in MPI implementation and applications. He codevelops and maintains AzequiaMPI, an efficient thread-based fully MPI 1.3 conformant thread-based MPI implementation.
He is has also carried out work in High Performance Reconfigurable Computing, producing MPI implementations for commercial distributed platforms of digital signal processing as well as for soft-core processors in networked FPGA's. Finally, he deals with the problem of finding the roots of arbitrarily high degree polynomials through parallel geometric methods.
