摘要： Techniques are provided for hardware-accelerated relational joins. A first table comprising one or more rows is processed through a hardware accelerator. At least one join column in at least one of the one or more rows of the first table is hashed to set at least one bit in at least one bit vector. A second table comprising one or more rows is processed through a hardware accelerator. At least one join column in at least one of the one or more rows of the second table is hashed to generate at least one hash value. At least one bit vector is probed using the at least one hash value. A joined row is constructed responsive to the probing step. The row-construction step is performed in the hardware accelerator.

摘要： A method and apparatus for managing CPU resources of a logically partitioned computing environment without shared memory access. A logical partition needing additional resources sends a message requesting such resources to a central domain manager, which sends messages to other partitions in the same group requesting that they assess their ability to donate resources to the requesting partition. Upon receiving such assessment request, each logical partition assesses its ability to donate resources to the requesting partition and responds accordingly to the domain manager. If at least one partition responds that it can donate resources to the requesting partition, the domain manager sends a message to a selected donor partition requesting that it reconfigure itself to donate resources to the requesting partition. Upon receiving a notification from the donor partition that it has successfully reconfigured itself, the domain manager notifies the requesting partition, which reconfigures itself to accept the donated resources.
摘要翻译：一种用于管理逻辑分区计算环境的CPU资源而不进行共享存储器访问的方法和装置。需要额外资源的逻辑分区将向中央域管理器发送请求这样的资源的消息，该中央域管理器将消息发送到同一组中的其他分区，请求他们评估其向请求分区捐赠资源的能力。在收到此类评估请求后，每个逻辑分区评估其向请求分区捐赠资源的能力，并相应地响应域管理器。如果至少一个分区响应它可以向请求分区捐赠资源，则域管理器向选定的供体分区发送一条消息，请求重新配置自己以将资源捐赠给请求分区。在从捐赠者分区接收到已经成功重新配置的通知之后，域管理器通知请求分区，其重新配置自己以接受所捐赠的资源。

摘要： A method, information processing system, and computer readable storage medium are provided for dynamically managing accelerator resources. A first set of hardware accelerator resources is initially assigned to a first information processing system, and a second set of hardware accelerator resources is initially assigned to a second information processing system. Jobs running on the first and second information processing systems are monitored. When one of the jobs fails to satisfy a goal, at least one hardware accelerator resource in the second set of hardware accelerator resources from the second information processing system are dynamically reassigned to the first information processing system.
