SaC is an array programming language predominantly suited for application areas
such as numerically intensive applications and signal processing.
Its distinctive feature is that it combines high-level program specifications
with runtime efficiency similar to that of hand-optimized low-level specifications.
Key to the optimization process that facilitates these runtimes is the
underlying functional model which also constitutes the basis for implicit
parallelization.
This makes SaC ideally suited for utilizing the full potential of modern
CMP
architectures such as multi-cores or the Cell processor.

The pre-alpha version of our new benchmarking tool named
UniBench goes live.
It aims at collecting and collating benchmarking results
for various languages / benchmarks / machines etc.
Although the user interface is still very rough around the edges
people can now play around with it. If you are interested in
contributing benchmarks / languages / compilers / machines etc.
please contact
the webmaster of that site for an appropriate login.
