BIOS Setup
Node Interleave
AMD Opteron CPU supports a mode called node interleave. W hen node inter-
leave is
disabled
, the memory controller maps the local memory of each pro-
cessor to a single contiguous range of physical addresses. This allows the
operating system to map user data to local memory, whenever possible, to
allow programs to access data the most rapidly. W hen node interleave is
enabled
, physical addresses are partitioned into 4KB blocks, and alternated
among the processors. The operating system is then unable to use NUMA
optimizations, and the memory space is treated as if the system were an SMP
system.
SW M em Hole Remap
p
This setting enables the software to remap the physical memory to an address
higher than 4GB.
