Algorithm 1 Pull execution of a graph kernel 1: for dst in G do 2: for src in G:incoming neighs(dst) do 3: dstData[dst] += srcData[src] 解读算法1:前两行(1-2)主要是通过OA数组找到目标节点,再通过NA找到其邻接的节点,第三行(3)描述的是具体执行的操作,根据需要对目标节点的邻接节点进...
A method, system and computer program product for cache replacement. The present invention leverages Belady's optimal replacement algorithm by applying it to past cache accesses to inform future cache replacement decisions. The occupied cache capacity of a cache is tracked at every time interval ...
The results of the experiments show the optimal solutions for sequential and parallel dense matrix multiplication algorithm. As the number of operations does not depend on cache replacement policy, we define and determine the average memory cycles per instruction that the algorithm performs, since it ...
update: Micheal Shekelyan and Graham Cormode pointed out that a version of the sparse Fisher-Yates algorithm is also in a preprint in Arxiv:CacheDiff: Fast Random Sampling(Bui 2015). They also have a very recentpaper(with code) on another neat method for in order sampling. It cleverly use...
As stretch is widely adopted as a performance metric for variable-size data requests, we proposed a broadcast scheduling algorithm to optimize the system performance in terms of stretch. One nice property of the proposed algorithm is that it is extremely simple and the computation overhead is ...
Both constants are greater than 1.37 under the best known algorithm by Williams [51]. We remark that even though the leakage rate of the previous constant- component constructions depends on the circuit size |C|, there is a generic way to get rid of the dependency by using FHE. We can ...
and the cache employs any one of a large family of removal policies that includes LRU. The miss costs associated with individual requests may be completely arbitrary, and the cost of cache storage need only be monotonic. We use an efficient single-pass simulation algorithm to compute aggregate...
Recent work has demonstrated that, cache space is often poorly utilized. However, no previous work has yet demonstrated upper bounds on what a cache or local memory could achieve when exploiting both spatial and temporal locality. Belady's MIN algorithm does yield an upper bound, but exploits on...

We develop an online structure that keeps track of the cache contents of the optimal offline algorithm. Based on this structure we design the algorithm class OPTMark which has the best possible competitive ratio and performs well on real-world traces. 展开 ...
