3.3.6 Some remarks on portability

Operations in 3.3.1 - 3.3.5 have been built on the following conditions.

1. There is a given topology, here a hypercube. If the hypercube is not available physically then it must be constructed logically on the given topology $\longrightarrow$ TRINIT
2. Send via link $\longrightarrow$ SEND/SMALL>_CHAN
3. Receive via link $\longrightarrow$ SEND/SMALL>_RECV

Only those 3 routines depend on hardware and operating system. All remaining routines should base on these three basic routines !
$\Rightarrow$ Code is portable

Ex.: Our own library libCubecom.a is available under MPI, PVM, Parix, nCube, Paragon, Standalone(3L), Helios, ...  .
