This board support package is designed to run under the Sun Hypervisor (SUN4V)8 on the following Sun Microsystems UltraSPARC T2 Netra series: * Netra CP3260 (Monza) * Netra T5220 (Turgo) * Netra T5440 (Congo) * Reference Development Platform (RDK) The CP3260, T5220, and RDK support the UltraSPARC T2 "Niagara2" processor with up to 8 cores. Each core supports 8 concurrent threads (or hardware strands), for a total of up to 64 virtual processors.The T5440 supports a dual UltraSPARC T2+ "Niagara2+" processor configuration, 23 with up to 8 cores per chip. Each core supports 8 concurrent threads. A total of up to 128 virtual processors are supported by the T5440. The T5440 is a NUMA architecture, as each T2+ processor has two memory controllers and the processors are connected by a high speed link.
