==Allocating memory aligned to cache lines==
It would be beneficial to allocate memory aligned to [[cache line]]s. If an array is partitioned for more than one thread to operate on, having the sub-array boundaries unaligned to cache lines could lead to performance degradation due to [[false sharing]]. Here is an example to allocate memory (double array of size 10) aligned to cache of 64 bytes.
