Franz Franchetti is a full Professor (with indefinite tenure) in the Department of Electrical and 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 leads three DARPA projects in the BRASS, HACMS, and PERFECT programs and is PI/Co-PI on a number of federal and industry grants.

Dr. Franchetti is Faculty Director of Information Technology Services in the ECE Department at Carnegie Mellon University. He is also CTO and Co-Founder of Spiral Gen, Inc., a Pittsburgh area startup that commercializes the Spiral technology. Previously, he has been Thrust Leader of the Security Thrust in Carnegie Mellon’s SRC Smart Grid Research Center and Faculty Senator for the ECE Department at Carnegie Mellon.

Professor Franchetti is Immediate Past President of the Austrian Scientists and Scholars in North America (ASciNA), and currently leads the ASciNA Western Pennsylvania chapter. Please contact him if you are an Austrian academic in the Greater Pittsburgh area.

Franz has been playing the electric guitar on-stage in various rock bands since 1993. Watch him perform live or visit Wr. Neustadt’s newcomer festival SCHMU, where he performed and served as stage engineer.

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 was developed over 20 years by the SPIRAL team under funding from DARPA (OPAL, DESA, HACMS, PERFECT, BRASS), NSF, ONR, DoD HPC, JPL, DoE, CMU SEI, Intel, Nvidia, and Mercury. The open sourcing of SPIRAL is an ongoing effort. The initial open source version of SPIRAL was supported by DARPA PERFECT.

Please subscribe to to stay up-to-date regarding SPIRAL updates and new releases.

Register for the SPIRAL tutorial at HPEC 2019. See also [Overview], [Walk-Through], and [SPIRAL User Manual].
