Explore the essentials of memory management in operating systems, including techniques, strategies, and common challenges faced in efficient memory allocation.
Highly parallel algorithms for access to system data structures lie at the core of effective memory allocation strategies as well as solutions to other parallel systems problems. In this paper, we investigate four algorithms, all based on the first fit approach, that provide different granularities ...
The memory allocation system has no prior knowledge of the sequence of memory allocations and frees that might be requested by applications. The allocator algorithms attempt to maximize the size of contiguous blocks within the heap over time to ensure that the heap does not get fragmented. A frag...
The alloc and free algorithms. A CPU, Depot, and Slab layer exists for each cache in the system. But how many caches are there? Once again, kstat can give us the answer: osol-box$ kstat -l -c kmem_cache -s slab_alloc […] unix:0:clnt_clts_endpnt_cache:slab_alloc...

If code could be magically rearranged to ensure all memory requests were satisfied in the fast caches, the program would speed up substantially. In practice, this is only possible in unusual circumstances because ordinarily the program's algorithms dictate the order of memory accesses. A more f...
