Author	SHA1	Message	Date
Constantin Fürst	ef8286da17	unset the weak-wait-flag on deallocation for CacheData which is where completion guarantee is required, also extend some comments in CacheData	11 months ago
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	322eb43cbc	add flag for early abort in access if no entry is present	11 months ago
Constantin Fürst	972440d19f	repair flags implementation	11 months ago
Constantin Fürst	b3607329a6	add a flags-concept to cacher, add the option to select whether to handle pagefaults or not	11 months ago
Constantin Fürst	20b7820e61	implement different load balancing technique suited for smaller task sizes maybe	11 months ago
Constantin Fürst	a72a26dbee	remove cout/cerr output from cache and benchmark to not falsify results	11 months ago
Constantin Fürst	c786d4d682	allow weak waiting which returns immediately if dsa has not yet finished	11 months ago
Constantin Fürst	053bb949ce	reset cacher to cpp api implementation	11 months ago
Constantin Fürst	2f17a38ef0	select device via jobs node parameter so we can skip the numa affinity change, also properly delete jobs in destructor	11 months ago
Constantin Fürst	aaaaa16e94	switch dsa cache to job api to use efficient wait	11 months ago
Constantin Fürst	140ded012a	querry operation finished state in loop which could be more efficient	11 months ago
Constantin Fürst	e7d10fc2d2	use hardware path instead of automatic for cache	11 months ago
Constantin Fürst	bbdb2d9588	prevent another type of deadlock that could arise from destroying a CacheData instance that never had tasks assigned to it due to waiting infinitely on it	11 months ago
Constantin Fürst	e9785f3f9e	prevent deadlocks by setting the cache pointer to the source address in case of errors	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	2b635d025d	add defaulted-constructor for cache which got implicitly deleted by deleting the copy constructor	11 months ago
Constantin Fürst	da38c048ca	pass data size to copy policy function too	11 months ago
Constantin Fürst	e4a681ac1e	delete the copy-constructor for cache as copying it is undesired behaviour	11 months ago
Constantin Fürst	e570a6fe69	reduce the line-count of the switch statement for dml::StatusToString by inlining return with case statements	11 months ago
Constantin Fürst	0fdf650fe4	improve the class-comments for Cache and CacheData, also free incomplete_cache_ if it has not been waited for (see comment on this)	11 months ago
Constantin Fürst	8ba716353a	add Clear() function which forces flush on the entire Cache and remove non-warning/error status messages from the cacher	11 months ago
Constantin Fürst	d7c5c55208	turn library into single-header mode	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	53e05d096c	add even more comments and remove an old code line that modified the reference counter of cache data from the outside	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
