Master the Art of CPU or GPU for Inference With These 5 Tips

January 30, 2021

In the recent past, GPUs have garnered wide attention in Data Science and AI as a cost-effective method to improve performance and speed of training ML models with huge data sets and parameters, as compared to CPUs (Central Processing Units). It is even being used at large commercial scales. For example, search-engine Baidu uses GPUs to fast-track visual search, speech recognition, click-through-rate estimation and more. In this blog, we cover the how-tos for choosing the right processing units for your deep-learning models.

Understand the basics

In recent times, GPUs have made headlines for different reasons. For example, the Stanford AI lab created the world’s fastest Artificial Intelligence (AI) training performance beating Google Data Centre. While this comparison is fair on some levels, comparing CPUs and GPUs is a bit like apples to oranges – they both serve a different function. So let us understand the basic definitions and understand the hardware in question at the core level. The table below illustrates the major differences in functioning and technology.

CPUGPUCentral Processing UnitGraphics Processing UnitFew powerful cores.Many weak cores.Emphasises on low latency.Emphasises on high throughput.Suitable for serial processing.Suitable for parallel processing.Can do a handful of operations at once.Can do thousands of operations at once.Consumes or needs more memory than GPU.Requires less memory than CPU.Faster at answering complex questions. Faster at answering simple questions. Designed to maximise the performance of the entire job, processes multiple tasks at once.Designed to maximise the performance of one job, processes tasks one at a time.Runs host code.Runs CUDA code (NVIDIA GPUs).

FLOPS

For deep-learning models, in particular, we only want to compare parallel compute capabilities. The image below illustrates how the two processing units perform by comparing FLOPS per Clock Cycle.

Undoubtedly, GPU performance has skyrocketed over the last few years as compared to CPU performance. To understand why to consider this – a 20 core CPU can perform only 20 data-sets at a time. The best CPUs in the market today have 96 cores. Currently, a server can have 8 GPUs with ~5,000 cores per GPU for a total of up to 40,000 GPU cores! However, as mentioned in this blog, the computer architectures of the two hardware are now closer than ever, and the only bottleneck for CPUs is the memory bus optimisation.

What role do CPU and GPU play in deep learning

As mentioned before, we cannot offload all of the CPU workloads to GPUs. The table below describes which deep-learning tasks are better performed on CPU and GPU.

CPUGPUHigh-definition, 3D, and non-image-based deep learning on language, text, and time-series data.Training with several neural network layers or on massive sets of certain data, like 2D images.Suitable for sequential algorithms like  Markov models and support vector machines. More suitable for matrix-multiply with many parameters.Suitable for memory intensive applications.Currently the best GPU in the market, NVIDIA Tesla V100 has 32GB memory. If computation does not fit in memory of the GPU, operations will slow down significantly.

For a detailed analysis of CPU vs GPU performance in TensorFlow, you can refer to various research papers. In one of the papers, comparisons have been made for the following algorithms in neural networking – AlexNet, text classification and Mnist digit classification.

Some questions to ask before making the choice

For commercial applications, some factors to consider are:

  • As illustrated in the image below, there’s no doubt that GPUs have much higher memory bandwidth than CPU. But, it takes time for data transfer from CPU to GPU too. One important question to ask – is the increased overhead time to switch to GPU worth the effort?

(Source: https://medium.com/@shachishah.ce/do-we-really-need-gpu-for-deep-learning-47042c02efe2)

  • Number of computations: How large is my data set? In general, the larger your data set, the more inclined you should be towards using GPU.
  • Optimisation: Dense neural networks are not suited for GPU as parallelisation will be highly difficult. In other words, optimisation is much faster in the CPU. Before embarking on the journey, ask – does the amount of coding required far exceed the output?

Cost considerations

This is, of course, one of the most important factors to consider. When the number of parameters is low, CPUs are still cost-effective. You can also consider optimising CPU performance through MKL DNN or NNPACK. Another important issue to note is that the scaling of GPU clusters is not linear, as illustrated in the following image.

Most importantly, GPU compute instances that cost about 2-3X more than CPU. So if you don’t get equivalent performance-enhancing, stick with CPUs. If all the above criteria are met, GPUs are the way to go!

Now that you have a fair idea of the CPU vs GPU comparison, you can make better decisions for optimising speed, performance and cost on deep learning analysis. Check out more of our blogs to understand deeper topics like benchmarking.

Project Management for AI-ML-DL Projects

Managing a project properly is one of the factors behind its completion and subsequent success. The same can be said for any artificial intelligence (AI)/machine learning (ML)/deep learning (DL) project. Moreover, efficient management in this segment holds even more prominence as it requires continuous testing before delivering the final product.

An efficient project manager will ensure that there is ample time from the concept to the final product so that a client’s requirements are met without any delays and issues.

How is Project Management Done For AI, ML or DL Projects?

As already established, efficient project management is of great importance in AI/ML/DL projects. So, if you are planning to move into this field as a professional, here are some tips –

  • Identifying the problem-

The first step toward managing an AI project is the identification of the problem. What are we trying to solve or what outcome do we desire? AI is a means to receive the outcome that we desire. Multiple solutions are chosen on which AI solutions are built.

  • Testing whether the solution matches the problem-

After the problem has been identified, then testing the solution is done. We try to find out whether we have chosen the right solution for the problem. At this stage, we can ideally understand how to begin with an artificial intelligence or machine learning or deep learning project. We also need to understand whether customers will pay for this solution to the problem.

AI and ML engineers test this problem-solution fit through various techniques such as the traditional lean approach or the product design sprint. These techniques help us by analysing the solution within the deadline easily.

  • Preparing the data and managing it-

If you have a stable customer base for your AI, ML or DL solutions, then begin the project by collecting data and managing it. We begin by segregating the available data into unstructured and structured forms. It is easy to do the division of data in small and medium companies. It is because the amount of data is less. However, other players who own big businesses have large amounts of data to work on. Data engineers use all the tools and techniques to organise and clean up the data.

  • Choosing the algorithm for the problem-

To keep the blog simple, we will try not to mention the technical side of AI algorithms in the content here. There are different types of algorithms which depend on the type of machine learning technique we employ. If it is the supervised learning model, then the classification helps us in labelling the project and the regression helps us predict the quantity. A data engineer can choose from any of the popular algorithms like the Naïve Bayes classification or the random forest algorithm. If the unsupervised learning model is used, then clustering algorithms are used.

  • Training the algorithm-

For training algorithms, one needs to use various AI techniques, which are done through software developed by programmers. While most of the job is done in Python, nowadays, JavaScript, Java, C++ and Julia are also used. So, a developmental team is set up at this stage. These developers make a minimum threshold that is able to generate the necessary statistics to train the algorithm.  

  • Deployment of the project-

After the project is completed, then we come to its deployment. It can either be deployed on a local server or the Cloud. So, data engineers see if the local GPU or the Cloud GPU are in order. And, then they deploy the code along with the required dashboard to view the analytics.

Final Words-

To sum it up, this is a generic overview of how a project management system should work for AI/ML/DL projects. However, a point to keep in mind here is that this is not a universal process. The particulars will alter according to a specific project.
