Abstract: Embodiments are directed to progressively migrating source computer nodes where the source computer nodes perform a computer-implemented service. In one embodiment, a computer system determines that execution of the performed service is to be migrated from the source computer nodes to target computer nodes.

The computer system activates a first target subgroup corresponding to a first source subgroup, and deactivates the first source subgroup. In this manner, the first target subgroup replaces the first source subgroup. Still further, the target subgroups are scheduled to be created only after the first source subgroup has been deactivated.

Abstract: In shared-memory computer systems, threads may communicate with one another using shared memory. A receiving thread may poll a message target location repeatedly to detect the delivery of a message. Such polling may cause excessive cache coherency traffic and/or congestion on various system buses and/or other interconnects. A method for inter-processor communication may reduce such bus traffic by reducing the number of reads performed and/or the number of cache coherency messages necessary to pass messages. The method may include a thread reading the value of a message target location once, and determining that this value has been modified by detecting inter-processor messages, such as cache coherence messages, indicative of such modification. In systems that support transactional memory, a thread may use transactional memory primitives to detect the cache coherence messages. This may be done by starting a transaction, reading the target memory location, and spinning until the transaction is aborted.

Abstract: A computing platform may include heterogeneous processors (e.g., CPU and a GPU) to support sharing of virtual functions between such processors. In one embodiment, a CPU side vtable pointer used to access a shared object from the CPU 110 may be used to determine a GPU vtable if a GPU-side table exists. In other embodiment, a shared non-coherent region, which may not maintain data consistency, may be created within the shared virtual memory. The CPU and the GPU side data stored within the shared non-coherent region may have a same address as seen from the CPU and the GPU side. However, the contents of the CPU-side data may be different from that of GPU-side data as shared virtual memory may not maintain coherency during the run-time. In one embodiment, the vptr may be modified to point to the CPU vtable and GPU vtable stored in the shared virtual memory.

Abstract: Embodiments of the invention provide language support for CPU-GPU platforms. In one embodiment, code can be flexibly executed on both the CPU and GPU.

This includes sharing objects that may have virtual functions. Embodiments thus ensure the right virtual function gets invoked on the CPU or the GPU if a virtual function is called by either the CPU or GPU.
