Cross Memory Attach [LWN.net]
The basic idea behind cross memory attach is to allow MPI programs doing intra-node communication to do a single copy of the message rather than a double copy of the message via shared memory. The following patch attempts to achieve this by allowing a destination process, given an address and size from a source process, to copy memory directly from the source process into its own address space via

The SLUB allocator [LWN.net]
The slab allocator has been at the core of the kernel's memory management for many years. This allocator (sitting on top of the low-level page allocator) manages caches of objects of a specific size, allowing for fast and space-efficient allocations. Kernel hackers tend not to wander into the slab code because it's complex and because, for the most part, it works quite well. Christoph Lameter is o
