technical field

Background technique

With the rapid development of information technology, the design of server architecture is becoming more and more complex, making it difficult to test the server memory bandwidth.

Based on the server's complex system architecture and parallel computing methods, the Stream Benchmark test tool is generally used to test the memory bandwidth. It can firstly give a known scale of data A, calculate the memory bandwidth according to the established rules, count the time t spent, and then divide the data amount A by the time t, and the obtained value is the memory bandwidth B, that is, B= A/t. It can be seen that the memory bandwidth B is related to the amount of data A and the test time t, and when the value of A is fixed, the test time t is related to the number of threads opened.
