    Abstract: A primary data storage system is connected with a separate and external active archive storage system to consolidate data and allow active archive data to be managed based on primary storage system events. The primary data storage system may be managed and maintained by an external entity, and may include a manager module such as a resource manager. The active archive system may include several tiers of storage in a hierarchical storage system and logic for moving data between and among the tiers. As data processing milestones are completed or the state of data changes, in projects stored in the primary data storage system, task milestone or state change events are detected. Event detection can trigger data movement in the active archive solution. One or more software modules implementing the present invention may detect the events and trigger active archive operations based on the events.

    Abstract: A processor (600) in a distributed shared memory multi-processor computer system (10) may initiate a flush request to remove data from its cache. A processor interface (24) receives the flush request and performs a snoop operation to determine whether the data is maintained in a one of the local processors (601) and whether the data has been modified. If the data is maintained locally and it has been modified, the processor interface (24) initiates removal of the data from the cache of the identified processor (601). The identified processor (601) initiates a writeback to a memory directory interface unit (24) associated with a home memory 17 for the data in order to preserve the modification to the data. If the data is not maintained locally or has not been modified, the processor interface (24) forwards the flush request to the memory directory interface unit (22). Memory directory interface unit (22) determines which remote processors within the system (10) have a copy of the data and forwards the flush request only to those identified processors. The identified processors then remove the data from their respective caches in response to the flush request. If an identified remote processor has modified data, the identified remote processor initiates a writeback to the memory directory interface unit (22) for preservation of the modified data.

    Abstract: A method and computer program product for testing a high performance computing application performing a computation within a clustered computer arrangement is disclosed. The high performance computing arrangement performances computations across processors in parallel wherein the processors cooperate to perform the computation. The application can be tested by adding delay and therefore latency to one or more commands inside of the precompiled application. The addition of delay can be used to simulate the performance of different interconnects that are used within the high performance computing arrangement.

    Abstract: In an embodiment, a system includes a resource. The system also includes a first processor having a load/store functional unit. The load/store functional unit is to attempt to access the resource based on access requests. The first processor includes a congestion detection logic to detect congestion of access of the resource based on a consecutive number of negative acknowledgements received in response to the access requests prior to receipt of a positive acknowledgment in response to one of the access requests within a first time period.

    Abstract: Resource acquisition requests for a filesystem are executed under user configurable metering. Initially, a system administrator sets a ratio of N:M for executing N read requests for M write requests. As resource acquisition requests are received by a filesystem server, the resource acquisition requests are sorted into queues, e.g., where read and write requests have at least one queue for each type, plus a separate queue for metadata requests as they are executed ahead of any waiting read or write request. The filesystem server controls execution of the filesystem resource acquisition requests to maintain the ratio set by the system administrator.
