LEGaTO poster presented by Omar ali at ACACES 2019 (Summer School on Advanced Computer Architecture and Compilation for High-performance Embedded Systems).

1. The LEGaTO project has received funding from the European Union’s Horizon 2020
research and innovation programme under the grant agreement No 780681. www.legato-project.eu
The LEGaTO Software Toolchain
Low Energy Toolset for Heterogeneous
Computing
LEGaTO Project Goals
OmpSs-centric
Programming Model
Nanos + XiTAO based
runtime targeting
heterogeneous clusters
+
One order of magnitude
improvement in energy-
efficiency for heterogeneous
hardware through the use of
the energy-optimized
programming model and
runtime.
5× decrease in
Mean Time to
Failure through
energy-efficient
software-based
fault tolerance.
Size reduction
of the trusted
computing base
by at least an
order of
magnitude.
5× increase in FPGA
designer productivity
through the design of
novel features for
hardware design using
dataflow languages.
