## Introduction
### Energy Demand of Applications
<hr/>


- Total compute energy approaches world's energy production

  --> Drastic improvements in energy efficiency needed

<!--
- compute 2x every two years
- energy production 2% per year

- to meet future compute demands, drastic improvements in energy efficiency

## Introduction
### Memory Bound Workloads
<hr/>

- AI applications become increasingly memory-bound

  --> Instead of bringing the data to the processing, bring the processing to the data

<!--
- Emerging AI applications become increasingly memory-bound
- Roofline model
- Not limited by compute power but by memory
- researchers begin to consider PIM to circumvent memory bottleneck

- (drastically more parameters in GPT-3, operational intensity goes down)
