FLOPS (Floating Point Operations Per Second)

by Stephen M. Walker II, Co-Founder / CEO

What is FLOPS?

FLOPS, or floating-point operations per second, is a measure of computer performance, particularly useful in fields of scientific computations that require floating-point calculations. It is a more accurate measure than measuring instructions per second for such cases. FLOPS can be recorded in different measures of precision, such as 64-bit (double-precision floating-point format, abbreviated to FP64), 32-bit (FP32), and 16-bit (FP16) operations.

FLOPS, or floating-point operations per second, is a metric for computer performance that quantifies the number of floating-point calculations a system can perform in one second. This is crucial in areas requiring high precision like scientific computation, financial analysis, and 3D graphics.

The TOP500 supercomputer list, for instance, ranks systems based on their double-precision floating-point performance (FP64). In AI, FLOPS is used to estimate the computational complexity and efficiency of models, indicating the arithmetic operations needed for tasks such as training or inference.

Some common FLOPS units include:

  • KiloFLOPS (kFLOPS): 10^3 FLOPS
  • MegaFLOPS (MFLOPS): 10^6 FLOPS
  • GigaFLOPS (GFLOPS): 10^9 FLOPS
  • TeraFLOPS (TFLOPS): 10^12 FLOPS
  • PetaFLOPS (PFLOPS): 10^15 FLOPS
  • ExaFLOPS (EFLOPS): 10^18 FLOPS
  • ZettaFLOPS (ZFLOPS): 10^21 FLOPS
  • YottaFLOPS (YFLOPS): 10^24 FLOPS

FLOPS is used to compare the performance of supercomputers and other high-performance computing systems. For example, the TOP500 supercomputer list ranks computers by their 64-bit (double-precision floating-point format) FLOPS performance.

How many flops is a human of compute?

George Hotz introduced the "person" unit to equate AI computational power with human intelligence, setting it at 20 PetaFLOPs (PFLOPs). A "person-year" measures this capacity over time. This concept aims to make the vast capabilities of AI more comprehensible by comparing them to human brainpower.

The AI community, including figures like Andrej Karpathy, has debated the practicality and underlying assumptions of the "person" unit. Hotz himself contrasted the brain's efficiency with computers, estimating the brain's output at 162 GigaFLOPs (GFLOPs) based on energy consumption and neuron activity—significantly less than the 20 PFLOPs attributed to a "person."

Hotz further illustrated his unit by analyzing the training of the AI model LLaMA-65B, which amounted to 6329 PetaFLOP/s-days over 1,022,362 GPU-hours. In comparison, a human brain operating at 20 PFLOPs for 30 years would reach 219,000 PetaFLOP/s-days, highlighting the disparity between AI and human computational scales.

How are FLOPS calculated?

FLOPS are calculated by counting the number of floating-point operations (like multiplication, division, addition, subtraction) that can be performed each second. This measure is often used in the field of high-performance computing (HPC) and in assessing the computational requirements of AI models.

  • Single-precision FLOPS: These are calculated using single-precision floating-point numbers, which use 32 bits.
  • Double-precision FLOPS: These are calculated using double-precision floating-point numbers, which use 64 bits.

What is the difference between FLOPS and Gflops?

FLOPS (Floating Point Operations Per Second) and GFLOPS (GigaFLOPS) are metrics for computing performance, with GFLOPS representing one billion FLOPS. While FLOPS measures the number of floating-point calculations a computer can perform in one second, GFLOPS quantifies this in billions, making it a more practical unit for high-performance systems. For example, a computer with 1 GFLOPS can perform a billion calculations in one second, a task that would take a human nearly 32 years to complete at the rate of one calculation per second.

What is the significance of FLOPS in AI?

In the context of AI and deep learning, FLOPS is used to gauge the computational cost or complexity of a model or a specific operation within a model. It helps in understanding the computational resources required to train or run a particular AI model. For instance, a model with higher FLOPS would require more computational resources and might be slower, affecting throughput.

  • Model complexity: FLOPS can give an estimate of the complexity of an AI model. More complex models usually have higher FLOPS.
  • Training time: The number of FLOPS can also give an estimate of the time it would take to train the model.
  • Inference time: FLOPS can help estimate the time it would take for the model to infer, or make predictions.

FLOPS is also a critical measure for supercomputers, used to express their top speed or performance capability. It's used to compare supercomputers based on the number of floating-point calculations they can perform.

However, it's important to note that FLOPS is not always a perfect measure of performance, especially for biological systems like the brain, where many operations are performed using shortcuts that traditional computers do not use.

How are FLOPS impacting AI development?

FLOPS is significantly impacting AI development by providing a quantifiable measure of computational requirements. It helps developers and researchers estimate the resources and time required for training and inference, thereby aiding in efficient resource allocation and planning.

  • Resource allocation: FLOPS helps in efficient allocation of computational resources for AI model training and inference.
  • Planning: Knowing the FLOPS of an AI model can aid in planning and scheduling of AI tasks.
  • Performance benchmarking: FLOPS is often used as a performance benchmark for comparing different AI models or hardware.
  • Energy efficiency: FLOPS can also be used to measure the energy efficiency of AI computations.
