Does the Altix system support automatic parallelization?
Yes. You can have the ifort compiler automatically parallelize your program by adding the -parallel switch to your compilations. By also adding the switch -par_report3 you can also get a detailed report of how the compiler parallelized your program. Our experience is that the Intel compilers do not parallelize the code as well as the Origin MIPSPro compilers. In particular, loops that contain intrinsic functions involving complex functions often do not parallelize and multiple loops are less likely to be merged into a single loop.
