计算Inference Time 时,如果用 Python 的用time.time()来测时间,这个函数不精确,至少应该用time.perf_counter()计算。time 库测量是在 CPU 上执行,由于 GPU 的异步特性,停止计时的代码行将在 GPU 进程完成之前执行。计时将不准确或与实际推理时间无关。 下面这个代码不合适,在 CPU 上计时且没有考虑 CPU 和 G...
Above code snippet times the execution of a single line of code that sums the range of numbers from 0 to 99. The timer parameter is used to specify a custom timer function that measures CPU time instead of wall-clock time.Other commonly used functions in timeitThe timeit module in Python ...
total_cputime(user+system) : CPU seconds spent by the package to fulfill the task, measured externally, but includes time spent to read vectors from files and float conversion. avg_walltime(per calculation) : Human-experienced seconds spent on each calculation, measured by the package iteself,...
(this is done by starting up mockup threads that mimic the workload based on the events in the trace. These threads can then replay the timings (CPU runtime and sleep patterns) of the workload as it occurred when it was recorded - and can repeat it a number of times, measuring its ...
A non-sampling profiler, purpose built to measure and optimise, performance of ultra-low-latency / real time systems. The main features include Targeted Profiling- Quantify how efficiently a section of code, runs in any Intel CPU and how much head room is left for further optimizations. ...
start_time = time.time() start_energy = pynvml.nvmlDeviceGetTotalEnergyConsumption(handle) time.sleep(6) # train_one_step() # or call API torch.cuda.synchronize() # Synchronizes CPU and GPU time. elapsed_time = time.time() - start_time ...

“User CPU time” gives the CPU time spent by the current process (i.e., the current R session) and “system CPU time” gives the CPU time spent by the kernel (the operating system) on behalf of the current process. The operating system is used for things like opening files, doing ...
It retrieves information about the CPU, memory, and network resource consumption during a period of time. ProcessPerformance is a portable open-source application implemented for the .Net Core platform. Memory and CPU usage is measured with the Process class in the System.Diagnostics namespace, ...
By default on Provision this is 20 seconds you can decrease this interval but this increases the CPU utilization. Keep this in mind when tuning your sampling intervals and hardware refresh rates. The logic below is generic for any switch that supports this. The logic is as follow...
