摘要： A system for distributed function execution, the system includes a host in operable communication with an accelerator. The system is configured to perform a method including processing an application by the host and distributing at least a portion of the application to the accelerator for execution. The method also includes instructing the accelerator to create a buffer on the accelerator, instructing the accelerator to execute the portion of the application, wherein the accelerator writes data to the buffer and 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 technique is provided for session aggregation in a distributed architecture having a server connected to blades. A master session is generated for collaboration by user clients, and the master session corresponds to one or more terminal sessions on the distributed architecture of the server connected to the blades. The one or more terminal sessions on the distributed architecture are aggregated in the master session. A determination is made that the user clients agree for one user client of the user clients to be authorized as a current command line user name, in response to requests that are sent to the user clients. The one user client is granted authorization to the current command line user name in the master session based on an agreement by the user clients.

摘要： Accelerator functions are cascaded, such that a result of one accelerator function is directly forwarded to another accelerator function, bypassing the processor requesting the functions to be performed. The cascading may be provided during compilation of a program specifying the functions to be performed, but can be dynamically reversed during runtime of the program.

摘要： Accelerators of a computing environment are managed in order to optimize energy consumption of the accelerators. To facilitate the management, virtual queues are assigned to the accelerators, and a management technique is used to enqueue specific tasks on the queues for execution by the corresponding accelerators. The management technique considers various factors in determining which tasks to be placed on which virtual queues in order to manage energy consumption of the accelerators.

摘要： A method, system, and computer program product for two-sided, dynamic cache injection control are provided. An I/O adapter generates an I/O transaction in response to receiving a request for the transaction. The transaction includes an ID field and a requested address. The adapter looks up the address in a cache translation table stored thereon, which includes mappings between addresses and corresponding address space identifiers (ASIDs). The adapter enters an ASID in the ID field when the requested address is present in the cache translation table. IDs corresponding to device identifiers, address ranges and pattern strings may also be entered. The adapter sends the transaction to one of an I/O hub and system chipset, which in turn, looks up the ASID in a table stored thereon and injects the requested address and corresponding data in a processor complex when the ASID is present in the table, indicating that the address space corresponding to the ASID is actively running on a processor in the complex. The ASIDs are dynamically determined and set in the adapter during execution of an application in the processor complex.

摘要： A method, hybrid server system, and computer program product, for managing access to data stored on the hybrid server system. A memory system residing at a server is partitioned into a first set of memory managed by the server and a second set of memory managed by a set of accelerator systems. The set of accelerator systems are communicatively coupled to the server. The memory system comprises heterogeneous memory types. A data set stored within at least one of the first set of memory and the second set of memory that is associated with at least one accelerator system in the set of accelerator systems is identified. The data set is transformed from a first format to a second format, wherein the second format is a format required by the at least one accelerator system.

摘要： An end-to-end record, request, response token-based protocol is used to facilitate processing of client jobs. This allows the client to forward analytical tasks of a job directly to an analytics cluster and to record an indication of such at a server. The accelerators of the cluster to perform the tasks are specified in a token provided by the server to the client.

摘要： Request processing within a computing environment is facilitated. Request processing and analytics processing for the request are performed substantially concurrently in order to improve efficiency of request execution. The analytics processing is at least commenced, and may complete, prior to receiving an indication of success or failure of the request processing. If request processing fails, analytics processing ceases, if not already complete, and results of the analytic processing are not used.
摘要翻译： 促进计算环境内的请求处理。 基本同时执行请求的请求处理和分析处理，以提高请求执行的效率。 在接收到请求处理的成功或失败的指示之前，分析处理至少开始并可以完成。 如果请求处理失败，分析处理将停止，如果尚未完成，并且不使用分析处理的结果。
