Compaq Alpha

Status

Cactus compiles with the OSF operating system (osf4.0, osf5.0, osf5.1).

Notes

1. Alpha compilers are sensitive to uninitialised memory (that is, you see a segmentation fault). If your application runs fine on a different architecture but gives a segmentation fault on an Alpha, uninitialised memory should be your first suspect. The thorn CactusUtils/NaNChecker provides a great mechanism for finding uninitialised memory.

2. With the native compilers and using pow(x,n), make sure that n is a float or double and not an int.
