DRAMA

DRAM Simulator

In order to run DRAMA, you must have python 3 with the following packages:

• os
• subprocess
• math
• configparser
• tqdm
• absl-py

DRAMA+ScaleSim

In this folder you can find the full implementation of DRAMA linked to Scale-Sim.

Link to SCALE-Sim: https://github.com/ARM-software/SCALE-Sim

Getting Started

1. Create a .cfg file inside 'configs' to define a new architecture for the network and DRAM. Architecture presets are used to define SCALE-Sim parameters, while DRAM preset are used to define DRAMA parameters.
2. Create a .csv file inside 'topologies' to define the topology of the network, as used by SCALE-Sim.
3. From within the 'DRAMA+ScaleSim' folder, run the following line:

Python3 scale.py -arch_config=<path to config> -network=<path to topology>

DRAMA Outputs

DRAMA outputs can be found under the path 'outputs/<run name>/DRAMA_stats

1. <run name>_DRAMA_dram_stats.csv - general DRAM statistics grouped by network layer and DRAM channel.
2. <run name>_<layer name>_DRAMA_dram_requests_trace.csv - cycle accurate DRAM request traces per network layer.

Channnel Simulator

In this folder you can find an implementation of a channel instance which can be incorporated in your code, using 3 simple methods:

• init - used to instantiate a single channel
• request - used to send a read/write request to the channel
• incrementClock - used to increment the channel's internal clock to a desired time

Further documentation for these methods can be found in Channel.py
