snmalloc

From the github README: snmalloc is a research allocator. Its key design features are: - Memory that is freed by the same thread that allocated it does not require any synchronising operations. - Freeing memory in a different thread to initially allocated it, does not take any locks and instead uses a novel message passing scheme to return the memory to the original allocator, where it is recycled. - The allocator uses large ranges of pages to reduce the amount of meta-data required. Details about snmalloc's design can be found in the accompanying paper[OP]. Differences between the paper and the current implementation are described here[0].

You may want to look at snmalloc, another allocator we did at Microsoft Research. It specifically targets these producer / consumer scenarios. https://github.com/microsoft/snmalloc And the paper, which I’ll be presenting tomorrow at ISMM: https://github.com/microsoft/snmalloc/blob/master/snmalloc.p...
