Instrumentation and optimization tools for heterogeneous programs

A computerized method for optimizing a heterogeneous program comprising:

• providing an intermediate representation of the heterogeneous program, wherein the heterogeneous program comprises components in different instruction sets;
• providing a set of navigation commands for each one of a plurality of elements in the intermediate representation of the heterogeneous program;
• providing a set of modification commands for each one of the plurality of elements in the intermediate representation;
• navigating to an element location within the intermediate representation using the navigation commands;
• and
• modifying the intermediate representation at the location using the modification commands to optimize execution of the heterogeneous program.

A computer-readable medium having computer-executable instructions to cause a computer to perform a method comprising:

• providing an intermediate representation of the heterogeneous program, wherein the heterogeneous program comprises components in different instruction sets;
• locating a position in the intermediate representation of the heterogeneous program through an application programming interface exported by the intermediate representation;
• and
• modifying the intermediate representation at the location through the application programming interface.

A computerized system, comprising:

• a processing unit;
• a system memory coupled to the processing unit through a system bus;
• a computer-readable medium couple to the processing unit through a system bus;
• a heterogeneous program for execution from the computer-readable medium by the processing unit;
• and
• pre-defined performance tools executed from the computer-readable medium by the processing unit, wherein the pre-defined performance tools cause the processing unit to modify an intermediate representation of the heterogeneous program, wherein the heterogeneous program comprises components in different instruction sets.

A computer-readable medium having computer-executable instructions stored thereon to instrument a heterogeneous program comprising:

• creating an intermediate representation for instrumentation instructions that gather statistics on the heterogeneous program, wherein the heterogeneous program comprises routines in different instruction sets;
• locating a point in the intermediate representation for the heterogeneous program at which to gather the statistics;
• and
• inserting the intermediate representation of the instrumentation instructions code at the point.
