Issues with Current HPEC Development
Inadequacy of Software Practices & Standards
• High Performance Embedded
Predator
Computing pervasive through DoD
applications
U-2
Global Hawk
MK-48 Torpedo
JSTARS
MSAT-Air
Rivet Joint
Standard
Missile
– Airborne Radar Insertion program
85% software rewrite for each hardware
platform
– Missile common processor
F-16
Processor board costs < $100k
Software development costs > $100M
– Torpedo upgrade
NSSN
AEGIS
P-3/APS-137
Two software re-writes required after changes
in hardware design

MITRE
Today – Embedded Software Is:
• Not portable
• Not scalable
• Difficult to develop
• Expensive to maintain

Quantitative Goals & Impact
Program Goals
The Three P’s
• Develop and integrate software
•
•
technologies for embedded
parallel systems to address
portability, productivity, and
performance
Engage acquisition community
to promote technology
insertion
Deliver quantifiable benefits
Portability:
reduction in lines-of-code to
change port/scale to new
system
Productivity: reduction in overall lines-ofcode
Performance: computation and
communication benchmarks
