Therefore, tests were developed that allowed comparison of different architectures. Software benchmarks are, for example, run against compilers or database management systems (DBMS).īenchmarks provide a method of comparing the performance of various subsystems across different chip/system architectures.Īs computer architecture advanced, it became more difficult to compare the performance of various computer systems simply by looking at their specifications. The term benchmark is also commonly utilized for the purposes of elaborately designed benchmarking programs themselves.īenchmarking is usually associated with assessing performance characteristics of computer hardware, for example, the floating point operation performance of a CPU, but there are circumstances when the technique is also applicable to software. In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it. ( Learn how and when to remove this template message)Ī graphical demo running as a benchmark of the OGRE engine. WikiProject Computer science may be able to help recruit an expert. The specific problem is: Outdated or deprecated sources. Most of CPUs are capable of automatic changing its frequencies and use slower frequencies when it is idle.This article needs attention from an expert in Computer science. Reference the output of lscpu and find out CPU number.$ find /sys/devices -name numa_node | grep '7d:00.0' | xargs cat Memory access of devices and tasks can be high speed cached. iperf3 or you need to taskset to set it manually. Some application can bind with its parameter e.g. This is helpful when process and PCI device use CPU in the same NUMA node. Sudo fio -rw=read -blocksize=128k -iodepth=128 -buffered=0 -direct=1 -ioengine=libaio -runtime=180 -filename=/dev/nvme0n1 -name=test -time_based -group_reporting -numjobs=4 -iomem=mmaphuge -mem=mmaphuge:/home/ubuntu/hugepages/file -output=output.txtįor single thread process, you can bind it to specific CPU. With Fio benchmark you can enable mmaphuge for iomem and mem options. Specify the number of hugepages ( here I am using 512 as an example, you might need to change that depending on your use case.)
