Method and system for compiler identification of code for parallel execution

A system for handling compiled program code comprising:

• a Just-In-Time, JIT, compiler for compiling input program code, wherein the JIT compiler is adapted to identify compiled program code to be executed in parallel;
• and
• at least one array processor unit comprising a plurality of processors for executing the compiled program code,
• wherein the JIT compiler is adapted to compile the input program code, whereby the compiled program code is generated from the input program code, and is further adapted to, while compiling the input program code, identify at least two parts of the compiled program code to be executed in parallel,
• wherein the at least one array processor unit is adapted to map the identified at least two parts of the compiled program code to be executed speculatively in parallel on at least two respective ones of the plurality of processors, and is further adapted to determine that the identified at least two parts of the compiled program code being executed speculatively in parallel are in conflict with each other, and
• wherein the system is adapted to, responsive to determining that if the identified at least two parts of the compiled program code being executed speculatively in parallel are in conflict with each other, repeat the mapping and the determining.
