Abstract: Systems and methods are provided for providing parallel muxing between servers in a cluster. One such system can include a cluster of one or more high performance computing systems, each including one or more processors and a high performance memory. The cluster communicates over an InfiniBand network. The system can also include a middleware environment, executing on the cluster, that includes one or more application server instances. The system can further include a plurality of muxers, wherein each application server instance includes at least one muxer. Each muxer can receive information from a plurality of threads to transmit to a different muxer on a different application server instance over the Infiniband network using a plurality of parallel channels.

Abstract: Embodiments of the invention provide systems and methods for detecting an analyzing memory leaks. According to one embodiment, a method of detecting a memory leak can comprise collecting instance count data for a number of instances of a plurality of classes in a memory heap. A correlation coefficient can be calculated for each of the plurality of classes in the memory heap. The correlation coefficient can represent a relevance of the class to a growth of the memory heap. Classes contributing to the growth of the memory heap can then be identified based on the correlation coefficient.

Abstract: Embodiments of the invention provide systems and methods for analyzing memory heap information for investigation into a memory leak caused by an application. According to one embodiment, a method of analyzing heap data can comprise obtaining the heap data from a memory. The heap data can represent a plurality of objects of one or more classes, each object identifying a referrer instance, a field in the referrer, and a referent instance. A statistical analysis can be performed on the heap data to identify objects within the heap that are contributing to a growth of the heap. The heap can be traversed based on the referrer instance of one or more objects identified as contributing to the growth of the heap to a root object identified as not contributing to the growth of the heap.
