Abstract: Methods, apparatus, and products are disclosed for paging memory contents between a plurality of compute nodes in a parallel computer that includes: identifying, by a master node, a memory allocation request for an application executing on the master node, the memory allocation request requesting additional computer memory for use by the application during execution; requesting, by the master node from a slave node, an available memory notification specifying to the master node the computer memory available for allocation on the slave node; allocating, by the master node, at least a portion of the computer memory available for allocation on the slave node in dependence upon the memory allocation request and the available memory notification; and transferring, by the master node, contents of a portion of the computer memory on the master node to the allocated portion of the computer memory on the slave node.

Abstract: Methods, apparatus, and products are disclosed for processing data access requests among a plurality of compute nodes. One compute node operates as a processing node, and one compute nodes operates as a requesting node. The processing node receives, from the requesting node, a data access request to access data currently being processed by the processing node. The processing node also receives, from the requesting node, a processing directive. The processing directive specifies data processing operations to be performed on the data specified by the data access request. The processing node performs, on behalf of the requesting node, the data processing operations specified by the processing directive on the data specified by the data access request. The processing node transmits, to the requesting node, results of the data processing operations performed on the data by the processing node on behalf of the requesting node.
