With the graph data scale constantly expanding, the personal computer has brought in severe challenge for the traditional graph partitioning because of its limited memory capacity. The streaming model has been applied in graph partitioning in recent years because it is more efficient than offline partitioning. However, the cache storage structure of original streaming method is inefficient for searching operations on the one hand, on the other hand, the efficiency gradually is reduced with the number of vertices which have been allocated increased because there is no space left for storing more in memory. A caching strategy for streaming algorithm is put forward in this paper including efficient cache storage structure, which uses the vertex and its neighbors' subset information as basic entry. The cache management module manages cache content. Our method is effective on the condition whether it has limitation to cache capacity or not. By using our cache strategy, it only takes about 25 minutes for partitioning twitter-2010 that have 1.4 billion edges while the original streaming method needs 42 minutes, As can prove the effectiveness and superiority of our method.

GPUs have been widely used in modern datacenters to accelerate emerging services such as Graph Processing, Intelligent Personal Assistant (IPA), and Deep Learning. However, current GPUs have very limited support for sharing. They are shared in a time-multiplexed manner in datacenters, which leads to low throughput. Previous studies on GPU kernel scheduling either target for fairness or only share GPUs statically, which cannot handle dynamically arriving kernels. Recent work has proposed hardware preemption mechanism for GPUs, enabling dynamic sharing. Exploiting this mechanism, we propose a preemption-aware kernel scheduling strategy for GPUs. Our strategy improves the throughput by running complementary kernels together. Furthermore, our strategy decides whether to preempt running kernels by weighing the performance benefit and overhead of the preemption with analytic models when new kernels arrive. Evaluation results show that our strategy improves the throughput by 20.1% over sequential execution, and 11.5% over a FCFS strategy.
