Abstract: A processing core in a multi-processing core system is configured to execute a sequence of instructions as a single atomic memory transaction. The processing core validates that the sequence meets a set of one or more atomicity criteria, including that no instruction in the sequence instructs the processing core to access shared memory. After validating the sequence, the processing core executes the sequence as a single atomic memory transaction, such as by locking a source cache line that stores shared memory data, executing the validated sequence of instructions, storing a result of the sequence into the source cache line, and unlocking the source cache line.

Abstract: A system and method for efficient automatic scheduling of the execution of work units between multiple heterogeneous processor cores. A processing node includes a first processor core with a general-purpose micro-architecture and a second processor core with a single instruction multiple data micro-architecture. A computer program comprises one or more compute kernels, or function calls. A compiler computes pre-runtime information of the given function call. A runtime scheduler produces one or more work units by matching each of the one or more kernels with an associated record of data. The scheduler assigns work units either to the first or to the second processor core based at least in part on the computed pre-runtime information. In addition, the scheduler is able to change an original assignment for a waiting work unit based on dynamic runtime behavior of other work units corresponding to a same kernel as the waiting work unit.

Abstract: A sampling based DBR framework which leverages a separate core for program analysis. The framework includes a hardware performance monitor, a DBR service that executes as a separate process and a lightweight DBR agent that executes within a client process. The DBR service aggregates samples from the hardware performance monitor, performs region selection by deducing the program structure around hot samples, performs transformations on the selected regions (e.g. optimization), and generates replacement code. The DBR agent then patches the client process to use the replacement code.

Abstract: A system and method for automatically migrating the execution of work units between multiple heterogeneous cores. A computing system includes a first processor core with a single instruction multiple data micro-architecture and a second processor core with a general-purpose micro-architecture. A compiler predicts execution of a function call in a program migrates at a given location to a different processor core. The compiler creates a data structure to support moving live values associated with the execution of the function call at the given location. An operating system (OS) scheduler schedules at least code before the given location in program order to the first processor core. In response to receiving an indication that a condition for migration is satisfied, the OS scheduler moves the live values to a location indicated by the data structure for access by the second processor core and schedules code after the given location to the second processor core.
