[Overview] This paper presents a kernel level page allocator which is
DRAM Bank-Aware. This allocator is able to allocate pages across cores
in a way that causes banks to be shared or partitioned depending on
user configuration. This can be used to provide more predictable
memory access to multicore software. The authors implemented their
memory allocator in a recent version of the Linux Kernel and compared
its performance with the existing buddy allocator.

[The good] This paper is well written. The issue of DRAM banks was not
familiar to me at the time of reading but was well explained which
motivated the rest of the paper well. The algorithm used is quite
straightforward and the explanation is easy to follow.

[The bad] While the authors acknowledge that the approach they take
bears similarity to multi-core page coloring[1,2,3,4] the novelty of
their work is not well established. This work appears to be a
relatively straightforward application of rudimentary page coloring
techniques. The related work section touches on these similarities but
does not establish any particular novelty aside from the fact that
this paper is addressing the problem of shared DRAM banks for the sake
of isolation and not shared caches.
