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	5578f06c80	adapt copy policy function to take data size as well and use this to only use destination nodes dsa engine for small data sizes on xeonmax	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	6ab88595b7	add test for the cache-flush logic which was previously not tested	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	4ddd96adcb	remove extra whitespace from output in main function	12 months ago
Constantin Fürst	e3e17cec7b	extend the main method of the small supplied test program to allow running on multiple threads	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	52566fc13b	print to cerr for bad states in the test-main	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
Constantin Fürst	395d307310	fix an issue with the freeing of data in the cacher	12 months ago
Constantin Fürst	f19c069b0f	always perform copy from src and dst node, add another log output about the split	12 months ago

Constantin Fürst	d396056230	provide first draft of implementations for the cachers functionality	12 months ago

Constantin Fürst	f91cd3202f	add project 'offloading cacher' and function declarations for the cacher in its header file	12 months ago
