Support for Performance Programming on CC-NUMA Architectures

Barbara Chapman [chapman@CS.UH.EDU]


A number of vendors market CC-NUMA machines, on which OpenMP is provided as
a  programming model. OpenMP is, however, a set of language extensions
designed for use on SMPs, and it does not contain features that would
enable
the user to control the locality of data, or to relate computations to the
location of data.  As a result, vendor-specific extensions have been
proposed to fill this gap.

In this talk, we consider how OpenMP is used to develop applications for
CC-NUMA architectures, considering what programming styles are likely to
provide high performance on such systems, and how OpenMP-level support for
such programming styles might be provided.
