Abstract

The invention discloses a method for optimizing a performance test on an internal memory of an Intel MIC (microphone) card. The method comprises the following steps of reconfiguring the whole running environment of the Intel MIC card; and adjusting and optimizing compiling on stream.c. The test can be ensured to last for a period of time, the bandwidth of the internal memory can reach a certain maximum value in a testing process, and the problem that the actual maximum peak value cannot be obtained is solved. By the internal memory bandwidth testing environment configuring and running method on the basis of a Stream tool, the bandwidth of the internal memory can reach the certain maximum value in the testing process, so that the test data of the bandwidth of the internal memory can be increased by about 4%.

Description

technical field [0001] The invention relates to a method for optimizing the memory performance test of an Intel MIC card. technical background [0002] With the continuous update of processor technology, processors with new features such as multi-core, high frequency, and pipeline optimization have appeared one after another, which has greatly improved the computing performance of server products. However, after research, it has been shown that the server product is a product that conforms to the wooden barrel principle. Only when each part is improved in a balanced manner can the performance of the entire platform be steadily improved. Studies have shown that as predicted by Moore's Law, the processing power of microprocessors will increase every year, but the speed of memory devices will only increase every year. Therefore, it is not the processing time of the processor that determines the maximum processing power of the processor, but the memory access and transmission t...
