1. At least one non-transitory machine-readable storage medium comprising instructions that when executed by a computing device, cause the computing device to: parse an application code to identify a loop instruction indicative of an instruction block comprising instructions that define a loop of which multiple iterations are capable of concurrent execution, the instructions comprising at least one call instruction to an executable routine capable of concurrent execution; and insert at least one coordinating instruction into an instruction sub-block of the instruction block to cause sequential execution of instructions of the instruction sub-block across the multiple iterations based on identification of the loop instruction.
