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: Systems and methods for swapping out and in pinned memory regions between main memory and a separate storage location in a system, including establishing an offload buffer in an interposing library; swapping out pinned memory regions by transferring offload buffer data from a coprocessor memory to a host processor memory, unregistering and unmapping a memory region employed by the offload buffer from the interposing library, wherein the interposing library is pre-loaded on the coprocessor, and collects and stores information employed during the swapping out. The pinned memory regions are swapped in by mapping and re-registering the files to the memory region employed by the offload buffer, and transferring data of the offload buffer data from the host memory back to the re-registered memory region.

Abstract: A runtime method is disclosed that dynamically sets up core containers and thread-to-core affinity for processes running on manycore coprocessors. The method is completely transparent to user applications and incurs low runtime overhead. The method is implemented within a user-space middleware that also performs scheduling and resource management for both offload and native applications using the manycore coprocessors.
