[Carpet] Test suites

[Ian Hinder]

Hi,

It looks to me like the Cactus test suite mechanism does not correctly
handle running a test suite on a different number of processors than
the test was originally run on with Carpet.  Because the CarpetIOASCII
1D and 2D output files are different depending on the processor
decomposition, the diffing that happens to verify results is not
enough.  We get test suite failures reported when they should not be.

Do people just rely on norms for testing that results are independent
of the number of processors?
