2013 R&D 100 Winner
Computers process information quickly, but they perform sequentially. Because clock speeds have stalled, future performance gains come almost solely from running sets of instructions concurrently. This will force fundamental changes for all computer components, making co-design (collaborative, simultaneous development of all system components) essential. Developed by a team led by Sandia National Laboratories, Mantevo Suite 1.0 is a promising approach to co-design that features an integrated collection of small software programs, called “miniapps”, whose performance characteristics model full-scale applications, yet require only a fraction of the lines of code. This makes miniapps easier to study, design and rewrite. Mantevo miniapps are freely available software products, accessible from mantevo.org as C++, C and Fortran source code, along with descriptions of capabilities and instructions for compiling and running relevant test cases. The base implementations include support for: sequential execution, shared memory execution using OpenMP, distributed memory execution using MPI and mixed distributed and shared memory execution using MPI+OpenMP.
