The Maisie runtime system for parallel execution is implemented on top of the PVM (3.0), Cosmic Environment, and Unix sockets. Currently, Maisie supports two parallel architectures: the Symult S2010 multicomputer and the `ghost cube' which allows a network of workstations running the Cosmic Environment to be treated like a multicomputer. The Maisie compile command provides an optional parameter -arch which may be used to indicate that the program is to be compiled for parallel execution; -arch s2010 indicates the Symult and -arch ghost represents the ghost cube. The compiled code is downloaded and executed on the parallel architecture by using the maycspawn command which provides an optional parameter -node to specify the number of processors (default=1) to be allocated. The following example illustrates compilation and execution of parallel Maisie programs.

%

mayc -arch pvm example.may -o example
This generates an executable file, example.s2010

%

mayc -arch ghost example.may -o example
This generates an executable file, example.gh

%

maycspawn -node 16 -arch s2010 example
Run the example program on 16 nodes of Symult s2010.

%

maycspawn example
Run the example programs on all nodes that are currently allocated to the user.
