Abstract
A compiler for compiling a computer program which is adapted for use with a data parallel computer. The compiler supports variables which involve parallelism. Variables which involve parallelism are parallel variables, templates for parallel variables called shapes, and pointers to parallel variables. For each variable involving parallelism declared globally in the source code, the compiler of the present invention emits in the target code a declaration of a global scalar variable. It further emits in the target code a start trap. When executed, the start trap allocates memory and a data structure for the global variables involving parallelism. The start trap also initializes the data structures and global variables involving parallelism. Finally, the compiler of the present invention emits in the target code one or more statements which, at run time, will cause the start trap to be invoked before the execution of any statement in which one of the global variables involving parallelism is read from or written to.
