    Abstract: There are provided source-to-source transformation methods for a multi-dimensional array and/or a multi-level pointer for a computer program. A method includes minimizing a number of holes for variable length elements for a given dimension of the array and/or pointer using at least two stride values included in stride buckets. The minimizing step includes modifying memory allocation sites, for the array and/or pointer, to allocate memory based on the stride values. The minimizing step further includes modifying a multi-dimensional memory access, for accessing the array and/or pointer, into a single dimensional memory access using the stride values. The minimizing step also includes inserting offload pragma for a data transfer of the array and/or pointer prior as at least one of a single-dimensional array and a single-level pointer. The data transfer is from a central processing unit to a coprocessor over peripheral component interconnect express.

    Abstract: The invention efficiently provides user code information for kernel level tracing approaches. It applies an advanced variation of stack walking called multi-mode stack walking to the entire system level and generates the unified trace where the user code and kernel events are integrated. The invention uses runtime stack information and internal kernel data structures. Therefore, source code for user level code and libraries are not required for inspection. The invention introduces the mechanism to narrow down the monitoring focus to specific application software and improve monitoring performance.
