摘要： A method includes processing an application by a host including one or more processors and distributing at least a portion of the application to an accelerator for execution. The method includes instructing the accelerator to create a buffer on the accelerator and instructing the accelerator to execute the portion of the application, wherein the accelerator writes data to the buffer. The method also includes instructing the accelerator to transmit the data in the buffer to the host before the application requests the data in the buffer. The accelerator aggregates the data in the buffer before transmitting the data to the host based upon one or more runtime conditions in the host.

摘要： A method, system, and computer program product for maintaining reliability in a computer system. In an example embodiment, the method includes managing workloads on a first processor with a first processor architecture by an agent process executing on a second processor with a second processor architecture. The method proceeds by activating redundant computation on the second processor by the agent process. The method continues by performing a same computation from a workload of the workloads at least twice. Finally, the method includes comparing results of the same computation. In this embodiment the first processor is coupled the second processor by a network, and the first processor architecture and second processor architecture are different architectures.

摘要： A method, system, and computer program product for maintaining reliability in a computer system. In an example embodiment, the method includes performing a first data computation by a first set of processors, the first set of processors having a first computer processor architecture. The method continues by performing a second data computation by a second processor coupled to the first set of processors, the second processor having a second computer processor architecture, the first computer processor architecture being different than the second computer processor architecture. Finally, the method includes dynamically allocating computational resources of the first set of processors and the second processor based on at least one metric while the first set of processors and the second processor are in operation such that the accuracy and processing speed of the first data computation and the second data computation are optimized.
