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; 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, the instruction sub-block preceding the call instruction within the instruction block and comprising an access instruction to retrieve data from an input resource, the computing device caused to enforce sequential execution of the instruction sub-block to cause data of the input resource to be retrieved by the access instruction in a predetermined order of the sequential execution of the instruction sub-block across the multiple iterations; allocate execution of each iteration of the multiple iterations to a thread of multiple threads; associate a unique identifier with each iteration of the multiple iterations; and employ the unique identifier of one iteration of the multiple iterations in the at least one coordinating instruction in another iteration of the multiple iterations to enforce sequential execution of the instruction sub-block across the one and the other of the iterations.
