Franz Franchetti

Carnegie Mellon University
Ph.D., Vienna University of Technology, 2003

Franz Franchetti is the Kavčić-Moura Professor of Electrical & Computer Engineering at Carnegie Mellon University. He received the Dipl.-Ing. (M.Sc.) degree in Technical Mathematics and the Dr. techn. (Ph.D.) degree in Computational Mathematics from the Vienna University of Technology in 2000 and 2003, respectively. In 2006 he was member of the team winning the Gordon Bell Prize (Peak Performance Award) and in 2010 he was member of the team winning the HPC Challenge Class II Award (most productive system). In 2013 he was awarded the CIT Dean's Early Career Fellowship by the College of Engineering of Carnegie Mellon University.


Dr. Franchetti's research focuses on automatic performance tuning and program generation for emerging parallel platforms and algorithm/hardware co-synthesis. He targets multicore CPUs, clusters and high-performance systems (HPC), graphics processors (GPUs), field programmable gate arrays (FPGAs), FPGA-acceleration for CPUs, and logic-in-memory and 3DIC chip design.  Within the Spiral effort, his research goal is to enable automatic generation of highly optimized software libraries for important kernel functionality. In other collaborative research threads, Dr. Franchetti is investigating the applicability of domain-specific transformations within standard compilers and the application of HPC in smart grids and material sciences. He has led four DARPA projects in the BRASS, HACMS, PERFECT, and PAPPA programs and is Co-PI in the DOE ExaScale Project and XStack program as well as DARPA DPRIVE. Recent interests include leveraging the SPIRAL system ( for quantum computing. Details can be found here:
 Open Source SPIRAL System 
Open Source SPIRAL is available here under non-viral license (BSD-style license). This is an initial version, and there will be an ongoing effort to open source whole system. Please let us know which parts of SPIRAL you are most interested in. Commercial support is available via SpiralGen, Inc.SPIRAL tutorial at HPEC 2019. See also [Overview], [Walk-Through], and [SPIRAL User Manual].
