20090157995 | DYNAMIC MEMORY MANAGEMENT IN AN RDMA CONTEXT - A method for dynamically managing memory to support one or more processes executing in a remote direct memory access (RDMA) environment is provided. The method includes inserting a descriptor in a shared descriptor table, the descriptor corresponding to a block of memory allocated to a heap by an operating system. The method further includes, in response to allocating a portion of the block of memory from the heap to a process, determining whether the process has an existing registration with an application program interface for the block of memory. If the process has no existing registration, registering the process the process is registered with the application program interface and a registration corresponding to the block of memory is stored in a private registration table of the process. Additionally, the method includes, in response to the process releasing the allocated portion of the block of memory to the operating system, de-registering with the application program interface and removing the registration from the registration table. When the block of memory is released to the operating system, other registrations corresponding to the block of memory in other private registration tables of other processes remain in the other registration tables. | 06-18-2009 |
20110161742 | Efficient Monitoring in a Software System - A monitoring of a server system during an execution of a server system processing logic, includes: during collection and storage of operational metrics by a given thread in a thread-local memory, determining that a checkpoint within the server system processing logic is reached; determining whether a threshold number of checkpoints have been encountered by the given thread; in response to the threshold number of checkpoints having been encountered, determining whether a threshold time interval since a last rollup of the collected operational metrics has been exceeded; and in response to the threshold time interval being exceeded, performing a rollup of the collected operational metrics from the thread-local memory to an accumulation point in a shared memory, where the accumulation point stores aggregated operational metrics from a plurality of threads. | 06-30-2011 |

20140181828 | PROCESSOR PROVISIONING BY A MIDDLEWARE PROCESSING SYSTEM - A middleware processor provisioning process provisions a plurality of processors in a multi-processor environment. The processors themselves may be subdivided in to one or more partitions or processing instances for which a single processing queue is created and a single kernel thread is started. User processing requests are portioned and dispatched across the plurality of processing queues and are serviced by the corresponding kernel process, thereby efficiently using available processing resources while servicing the user processing requests in a desired manner. | 06-26-2014 |
