1. A method of utilizing a kernel administration hardware thread of a multi-threaded, multi-core compute node of a parallel computer, the compute node comprising a kernel processing core and a plurality of parallel application processing cores, the kernel processing core comprising a plurality of kernel administration hardware threads, each application processing core comprising a plurality of hardware threads, the method comprising: assigning to the kernel administration hardware thread, by a kernel executing on the kernel processing core, a memory space of a hardware thread of one of the application processing cores; in response to the assignment of the kernel administration hardware thread to the memory space of the hardware thread, advancing, by the kernel administration hardware thread, the hardware thread to a next memory space associated with the hardware thread; and executing, by the kernel administration hardware thread, an instruction within the assigned memory space.
