摘要：

众核处理器适应于加速高吞吐率的计算密集型应用，而密码算法需要进行大量的数学计算，特别需要使用高吞吐率的计算平台。提出了一种面向众核平台的粗粒度并行加速框架，该框架不考虑算法内部的运算过程，将数据以计算函数为单位分配到众核协处理器上执行。使用MIC众核协处理器，采用三级并行结构及任务分配机制，提升了高吞吐率密码算法处理的并行性。针对多种密码算法应用的实验结果表明，该框架可充分利用众核平台实现粗粒度并行的高吞吐率加解密处理。

关键词: 众核平台, 密码算法, 高吞吐率, 粗粒度并行

Abstract:

Many-core processors are suitable for accelerating high-throughput computingintensive applications, while cryptography algorithms require large amounts of mathematical calculations and hence require high-throughput computing platforms. This paper proposes a coarse-grained parallel acceleration framework for many-core computing platforms. The framework does not take into account the internal computing process of the algorithm, and allocates the data to the many-core coprocessor for execution in units of computational functions. Based on the MIC many-core accelerator, the framework adopts the three-level parallel structure and task allocation mechanism, and develops the parallelism of the high-throughput cryptography algorithm. Experimental results for a variety of algorithms show that the framework can make full use of many-core computing platforms to achieve high-throughput encryption and decryption processing coarse-grained parallelism.

Key words: many-core platform, cryptography algorithm, high throughput, coarsegrained parallel
