Ą    Portable and Scalable Multi-platform Runtime Support
Efficiently support address translations and data movements
when mapping a shared address space onto a multiple
processor architecture
Develop an integrated runtime support system to carry out
address translation and communication optimizations; build
this on top of a message passing interface
Ą    Integrated Multilanguage Support
Allow different programming languages to share data
structures that are distributed across the memory hierarchy
of a scalable parallel system
  Đ    Develop common code and data descriptors, and routines
    that operate on them, for supporting data parallelism in
    HPLs
Design a common compiler data movement interface
specification that will provide a set of communication
standards for compiled code, ranging from very low
primitives that exploit special hardware properties to very
high level primitives directly coupled the the common array
and data structure formats

Ą    Software Engineering
System level test and validation of the Common Runtime
System requires development of a methodology and framework
for composing, executing and measuring systems built from
programs in multiple languages
Develop a methodology to allow ease of use, modification,
specialization, and extension of the Common Runtime System:
support new data structures, new language features, new
runtime mechanisms and algorithms, and new message passing
or distributed shared memory interfaces.
Ą    Interoperable Compilers
We will have seven compilers sharing the same runtime system
and be available for use and experimentation in
multilanguage systems
