摘要： A method of responding to requests using stream processing includes, responsive to a client request, assigning a processing thread for handling the client request. A return connection is established within the processing thread. A server request derived from the client request is sent to a stream server configured to interact with a plurality of stream processing nodes. The server request includes a thread identifier specifying the processing thread. The processing thread for handling the client request is maintained in an idle state pending a write response message from the stream server. Responsive to receiving the write response message comprising a stream processing result and the thread identifier from the stream server, the processing thread specified by the thread identifier is returned to an active state using a processor. A client response comprising the stream processing result is returned to the client over the return connection.

摘要： A method for faulty memory utilization in a memory system includes: obtaining information regarding memory health status of at least one memory page in the memory system; determining an error tolerance of the memory page when the information regarding memory health status indicates that a failure is predicted to occur in an area of the memory system affecting the memory page; initiating a migration of data stored in the memory page when it is determined that the data stored in the memory page is non-error-tolerant; notifying at least one application regarding a predicted operating system failure and/or a predicted application failure when it is determined that data stored in the memory page is non-error-tolerant and cannot be migrated; and notifying at least one application regarding the memory failure predicted to occur when it is determined that data stored in the memory page is error-tolerant.

摘要： Methods and systems for shuffling data to generate a dataset are described. A first map module may generate first pair data, and a second map module may generate second pair data, from source data. The first map module may insert the first pair data into a first local tuple space accessible to the first map module. The second map module may insert the second pair data into a second local tuple space accessible to the second map module. A shuffle module may request pair data that includes a particular key. The first and second pair data may be inserted into a global tuple space accessible by the first and second map modules. The shuffle module may identify the requested pair data in the global tuple space, and may fetch the identified pair data from a memory. The shuffle module may shuffle the fetched pair data to generate the dataset.
