CPU Time Example • Computer A: 2GHz clock, 10s CPU time • Designing Computer B – Aim for 6s CPU time – Can do faster clock, but causes 1.2 × clock cycles • How fast must Computer B clock be? € Clock Rate B = Clock Cycles B CPU Time B = 1.2×Clock Cycles A 6s Clock Cycles A =CPU Time A ×Clock Rate A =10s×2GHz=20×109 Clock Rate B

Throughput and CPU measurements There are many factors that can impact system throughput and CPU performance, and these can be measured with the goal of improving performance. The execution of a single map occurs in the context of a single thread. Therefore, additional processors will not improve the execution time of a single transformation. Throughput is usually measured in bits per second (bit/s or bps), and sometimes in data packets per second (p/s or pps) or data packets per time slot. The system throughput or aggregate throughput is the sum of the data rates that are delivered to all terminals in a network. Remember that raw throughput seeks to activate another physical CPU after only the primary thread on the first CPU becomes saturated. Adjusting the vpm_throughput_mode tunable will force more threads/logical processors to be utilized before the workload falls over to the next CPU. Describes throughput and latency for 10th Generation Intel® Core™ Processor based on Ice Lake microarchitecture. Processor utilisation: Throughput Given the current algorithm, how much potential is left on the given hardware? The algorithm running on the processor possibly is the bottleneck of the system. The metric we use for this balance is “”FLOPS per byte”.

Throughput and CPU measurements There are many factors that can impact system throughput and CPU performance, and these can be measured with the goal of improving performance. The execution of a single map occurs in the context of a single thread. Therefore, additional processors will not improve the execution time of a single transformation. Understanding and Tuning CPU Throughput | IBM Systems Media The higher you set vpm_throughput_mode, the more threads will be activated on each CPU before another full CPU is unfolded―or activated. Remember that raw throughput seeks to activate another physical CPU after only the primary thread on the first CPU becomes saturated. Performance can be measured as Throughput, Latency or Processor utilisation: Throughput. Given the current algorithm, how much potential is left on the given hardware? The algorithm running on the processor possibly is the bottleneck of the system. The metric we use for this balance is “”FLOPS per byte”.
