A key feature of the pC++ programming system is its ability to
transparently and efficiently support scaling of problem size and
machine size.
Clearly, the dominant performance concern is pC++'s ability to achieve
scalable performance.
As the problem size increases, pC++ should support
increased processing efficiency.
In response to increasing numbers of processors, pC++ should demonstrate
good speedup.
Scalability results for shared and distributed
versions of the pC++ system are given
below.
We also provide comparisons to Fortran results where appropriate.
