Constantin Fürst 3c90e24bc1 revert the cacher to allow load balancing control through the copy placement policy function which now selects on how many nodes the task is split again, and not just which nodes the task MAY run on (which was done experimentally) 11 months ago

Constantin Fürst fa23c6c50a improve the handler distribution and waiting on task completion for cacher 11 months ago
Constantin Fürst 7e48c96828 distribute multiple per-node locks for the cache state and allocate them on the respective numa node for fastest possible access 11 months ago

Constantin Fürst da38c048ca pass data size to copy policy function too 11 months ago

Constantin Fürst 4fa5ef6522 accept existing cache if the cached block is larger than the requested view 12 months ago
Constantin Fürst 7dfbed68fe handle allocation slightly different, introduce a separate function for cleaner code that does on-node memory allocation, first querry the available size and do not rely on numa_alloc_onnode to report nullptr if the size is not really available 12 months ago
Constantin Fürst e5b96727cd add missing inline specifier to functions as this is header-only code 12 months ago
Constantin Fürst 9c06bd4fa9 add class-definition comments and clear some double-newlines 12 months ago

Constantin Fürst 46de3151a2 add a lot of comments to the code, also handle errors in the dml handlers gracefully 12 months ago
Constantin Fürst c01eafedae refactor the cacher to reduce complexity, removes the access guarantees (relaxed,immediate,...), uses the fact that other tasks will wait on atomic value change for the cache-pointer if it is nullptr to add the entry to cache structure earlier reducing cost of two threads accessing new entry at the same time, splits the offloading-cache.hpp file into two with one containing the data-class (represents a cache entry and task) and the other containing the cacher itself 12 months ago
