Once an application is loaded and running, it can manage all the available memory on a node and use the full resources provided by the hardware.
Applications are started and controlled from a process called yod that runs on the host node.
Yod runs on a Sun frontend for the nCUBE 2, and on a service node on the Intel Paragon.
[2] The ideas in SUNMOS inspired PUMA, a multitasking variant that only ran on the i860 Paragon.
Intel ported PUMA and Portals to the Pentium Pro based ASCI Red system and named it Cougar.
