To support such architectures transparently, kernel subsystems can use the numa_mem_id() or cpu_to_mem() function to locate the “local memory node” for the calling or specified CPU. Again, this is the same node from which default, local page allocations will be attempted.

For optimal performance, the kernel needs to be aware of where memory is located, and keep memory used as close as possible to the user of the memory. Examples of NUMA machines include the NEC Azusa, the IBM x440 and the IBM NUMAQ. The 2.5 Linux kernel includes many enhancements in support of NUMA machines.

2 Linux NUMA Support The basic infrastructure for supporting NUMA hardware has been incorporated into the Linux 2.5 development kernel. This support in-cludes topology discovery and internal repre-sentation, memory allocation, process schedul-ing, and timer support. In addition there are kernel extensions in support of NUMA that

No standards govern NUMA interfaces. NOTES top The Linux NUMA system calls and /proc interface are available only if the kernel was configured and built with the CONFIG_NUMA option. Library support Link with -lnuma to get the system call definitions. libnuma and the required <numaif.h> header are available in the numactl package. However ...

Java 7 added support for NUMA-aware memory allocator and garbage collector. Version 2.5 of the Linux kernel already contained basic NUMA support, which was further improved in subsequent kernel releases. Version 3.8 of the Linux kernel brought a new NUMA foundation that allowed development of more efficient NUMA policies in later kernel releases.

Jun 16, 2014 · Next, we have a NUMA option (Numa Memory Allocation and Scheduler Support (NUMA)). This will allow the kernel to allocate memory used by the CPU on the local memory controller of the CPU. This support also makes the kernel more NUMA aware. Very few 32-bit systems need this feature, but some common 64-bit processors use this feature. I chose ...
