Replay execution of instructions in thread chunks in the chunk order recorded during previous execution

An apparatus, comprising:

• a recorder unit, when executed on a processor, is to generate an order of recorded chunks of instructions across a plurality of recorded threads based, at least in part, on log files generated from a previous execution of the program;
• a virtual machine unit, when executed on the processor, is to intercept an instruction of a chunk of instructions before the instruction is executed;
• and
• a replay module, when executed on the processor, is to:
• initiate an execution of the program that was previously executed, the executing program to have a plurality of threads, and each thread to have a number of chunks of instructions;
• determine that the chunk is an active chunk if the chunk is currently in line for execution according to the order of recorded chunks;
• and
• responsive to a determination that the chunk is the active chunk, execute the instruction.

At least one non-transitory machine accessible storage medium comprising code stored thereon, the code when executed on a machine, causes the machine to:

• generate an order of recorded chunks of instructions across a plurality of recorded threads based, at least in part, on log files generated from a previous execution of a program;
• initiate an execution of the program that was previously executed, the executing program to have a plurality of threads, each thread to have a number of chunks of instructions;
• intercept an instruction of a chunk before the instruction is executed;
• determine that the chunk is an active chunk if the chunk is currently in line for execution according to the order of recorded chunks;
• and
• responsive to a determination that the chunk is the active chunk, execute the instruction.
