Method for generating optimized vector instructions from high level programming languages

A computer readable storage medium having instructions recorded therein, wherein said instructions are operable to:

• examine a block of program code;
• evaluate a plurality of operators within said block of program code;
• select one or more sets of said operators for parallel execution;
• define memory locations for a plurality of operands corresponding to said one or more sets of said operators, wherein said memory locations of operands corresponding to one of said sets of said operators are adjacent;
• generate vector instructions for said one or more sets of said operators;
• and
• wherein said instructions are further operable to rate each of said one or more potential sets of operators based upon a number of ancestor operators with which a given operator is associated.

A method for selecting operators in a computer program for parallel execution, the method comprising:

• (a) examining a plurality of operators;
• (b) determining a rating corresponding to each of a plurality of sets of said plurality of operators, wherein said rating is based upon a number of ancestor operators with which a given operator is associated;
• (c) identifying one of said plurality of sets having a highest rating;
• and
• (d) selecting said identified set for parallel execution.
