Description
Technical Field
The invention belongs to the technical field of server testing, and particularly relates to a method, a system, a terminal and a storage medium for automatically configuring the number of NUMA nodes.
Background
SPEC jbb2015 is a standard performance evaluating organization of international authority, SPEC is mainly used for measuring Java system performance including JRE performance, operating system performance and underlying hardware, and most servers of various large enterprises test the JRE performance of CPUs, the operating system performance, Java service application performance and expandability of the CPUs through SPEC. Modern servers all adopt a Non-Uniform Memory Access (NUMA) architecture, the NUMA divides the server into a plurality of nodes ("nodes"), each Node has a plurality of CPUs therein, the nodes use a common Memory controller therein, and the nodes are connected and information exchanged through an interconnection module. The NUMA node accesses the memory of the local node without passing through the interconnection module, the access speed is the fastest, and the NUMA node accesses the memory of the non-local node without passing through the interconnection module, so the access speed is slower.
The SPEC jbb2015 test provides a testing mode of multiple JVMs (Java virtual machines), when testing multiple JVMs, it should be ensured that each JVM is correspondingly bound to each NUMA Node in the current testing environment, so that each JVM only accesses the memory of the Node as far as possible, and the Java performance of the system is highest, that is, the number of the test parameters GROUP is required to be equal to the number of NUMA nodes (s)) in the current testing environment, and binding is performed.
In the above method, if the test is run according to the default configuration, and at this time, the GROUP _ COUNT is 1, the SPEC jbb2015 test only runs one GROUP according to the default value, and the server generally does not have only one NUMA Node according to the difference of the CPU, often has multiple NUMA Nodes, resulting in that the GROUP _ COUNT is not equal to NUMA Nodes(s), so the default configuration cannot satisfy the test optimal performance configuration, and a tester needs to manually modify the value of the GROUP _ COUNT in the test script to the current number of NUMA Nodes, which is tedious in process, and often forgets to modify the value, and directly runs the test according to the default value, resulting in waste of working resources.
