Abstract: Embodiments of the invention provide efficient scheduling of parallel computations for higher productivity and performance. Embodiments of the invention provide various methods effective for affinity driven and distributed scheduling of multi-place parallel computations with physical deadlock freedom.

Abstract: Techniques for providing safe user-managed memory are provided. The techniques include performing memory allocation in constant time, performing memory de-allocation in constant time, performing memory access overhead for safety checking in constant time, and using the memory allocation, memory de-allocation and memory access overhead to protect at least one memory access, user-specified allocation and de-allocation with at least one exception for said user-managed memory.

Abstract: Embodiments of the invention provide a table-free technique for detecting all temporal and spatial memory access errors in programs supporting general pointers. Embodiments of the invention provide such error checking using constant-time operations. Embodiments of the invention rely on fat pointers, whose size is contained within standard scalar sizes (up to two words) so that atomic hardware support for operations upon the pointers is obtained along with meaningful casts in-between pointers and other scalars. Optimized compilation of code becomes possible since the scalarized-for-free encoded pointers get register allocated and manipulated. Backward compatibility is enabled by the scalar pointer sizes, with automatic support provided for encoding and decoding of fat pointers in place for interaction with unprotected code.
