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.
