counting FLOPs of a batch normalization layer

Could you please let me know how I can count the number of FLOPs related to the batch normalization layer theoretically? (FLOPs: Note that s is lowercase, which is the abbreviation of FLoating point OPerations (s stands for plural), which means…

pytorch error: The size of tensor a (56) must match the size of tensor b (28) at non-singleton dimension 3

Using count_ops to calculate FLOPS for a neural network model gives me the error mentioned in the title. I have changed a pretrained model (resnet18) by using assignments. My goal is to calculate the FLOPS for each edited model (to make sure the…

Is it possible that the inference time is large while number of parameters and flops are low in pytorch?

I calculated flops of network using Pytorch. I used the function 'profile' in 'thop' library. In my experiment. My network showed that Flops : 619.038M Parameters : 4.191M Inference time : 25.911 Unlike my experiment, I would check the flops and…

Difficulty understanding FLOPS in this scenario

Given FLOPS are the floating point operations per second, would that not be dependent on the power of the machine rather than the model and how many parameters it has? What am I missing here? Screenshot is from "EfficientNet: Rethinking Model…

Theoretical maximum performance (FLOPS ) of Intel Xeon E5-2640 v4 CPU, using only addition?

I am confused about the theoretical maximum performance of the Intel Xeon E5-2640 v4 CPU (Boardwell-based). In this post, >800GFLOPS; in this post, about 200GFLOPS; in this post, 3.69GFLOPS per core, 147.70GFLOPS per computer. So what is the…

What is the difference between floating point instruction and floating point operation?

I've been studying computer performance metrics and I have a doubt about MFLOPS. By definition, MFLOPS is (NumberOfFloatingPointOperations/ExecutionTime*106). At first, I assumed that operation and instruction were the same. However, I discovered…

How to properly calculate CPU and GPU FLOPS performance?

Problem I'm trying to calculate CPU / GPU FLOPS performance but I'm not sure if I'm doing it correctly. Let's say we have: A Kaby Lake CPU (clock: 2.8 GHz, cores: 4, threads: 8) A Pascal GPU (clock: 1.3 GHz, cores: 768). This Wiki page says that…

How can I compute number of FLOPs and Params for 1-d CNN? Use pytorch platform

My network is a 1d CNN, I want to compute the number of FLOPs and params. I used public method 'flops_counter', but I am not sure the size of the input. When I run it with size(128,1,50), I get error 'Expected 3-dimensional input for 3-dimensional…

Counting the number of flops

For the following pseudocode; I think that the number of flops is 2n^3. However, I am unsure that this is correct as the for loops make me doubt it. (Note: aij and xij represent entries for matrices A and X respectively) for =1:   for =1:     for…

How does one compute FLOPS from time elapsed for a computation?

One can see from this tutorial on the usage of Intel MKL DFTs that Dr. Andrey E. Vladimirov uses the time elapsed during a task, namely t1-t0, to compute the number of GigaFLOPS using GF/s = HztoPerf/(t1-t0) where HztoPerf = 5.0 * 1e-9 *…
