# cadCAD Golem ## Work in progress - due date 5 January 2021 - (https://gitcoin.co/issue/golemfactory/hackathons/3/100024408) This package is a wrapper for cadCAD to dispatch the simulation workload to multiple Golem nodes. [cadCAD](https://github.com/cadCAD-org/cadCAD) is a Python package that assists in the processes of designing, testing and validating complex systems through simulation, with support for Monte Carlo methods, A/B testing and parameter sweeping. [Golem](https://golem.network/) is a global, open source, decentralized supercomputer that anyone can access. It is made up of the combined power of users' machines, from PC's to entire data centers. ## Note * Jupyter Notebook support added. * The Golem network is still under development, and not all nodes behave perfectly. If your simulatino fails, try again a few times. ## Getting Started ### Initialise/Create environment and working directory If you are already using cadCAD, activate the virtual environment that you use for cadCAD. This might look something like: ```bash source ~/.venv/cadcad ``` If you do not yet have a working directory or virtual environment, creat both and activate. Something like so: ```bash mkdir -p ~/projects/cadcad-exp cd ~/projects/cadcad-exp python3 -m venv .venv source .venv/bin/activate ``` Now you have an isolated environment where you can install your python packages without fear of bloating the rest of your system. ### Install cadcadgolem Requires [>= Python 3.8](https://www.python.org/downloads/) #### Install Using [pip](https://pypi.org/project/cadCAD/) ```bash $ pip3 install cadcadgolem ``` ### Install *yagna daemon* The Yagna daemon is what you will use to interface with the Golem network. It runs in the background, waiting for API calls from your applications, in our case, from *cadcadgolem*. To install yagna, you can use their helper script: ``` curl -sSf https://join.golem.network/as-requestor | bash - ``` For manual installation instructions, see: (https://handbook.golem.network/requestor-tutorials/flash-tutorial-of-requestor-development) To check it is installed corretly, run: ``` yagna --version ``` ### Prepare *yagna daemon* To run the yagna daemon, follow the following sequence. This sequence will need to be followed everytime you restart *yagna*. #### Start the daemon This will initialise the daemon ``` yagna service run ``` #### Generate the app key (*This only has to done once after initial install of `yagna`*) ``` yagna app-key create requestor ``` This should produce a 32-character-long hexadecimal app key that you need to note down as it will be needed in your code to run the requestor agent. #### Get some coinage Golem currently has a faucet where you can get free tokens to pay for the processing that you will perform on the network. ``` yagna payment init -r ``` #### Check that the fund transfer was successfull. ``` yagna payment status ``` #### Add your app-key to your code When using cadcadgolem, a dictionary is passed that contains the parameters for your interaction with the network. One of them is yor app-key, which allows you to speak to the *yagna* daemon that you started earlier. Place your app-key into your dictionary (see dictionary below). ## Using cadcad Golem To use cadcad Golem, you need to do three things: 1. Import the cadcad Golem Ambassador: ``` from cadcadgolem.golem_embassy import Ambassador ``` 2. Define the golem_conf dictionary: ``` golem_conf = { 'NODES': 3, # Number of nodes to utilise from the Golem Network. If you've got a big simulation to run, try pushing this up to 30. Remember you need at least twice as many simulation runs as you have nodes. 'BUDGET': 10.0, # Maximum amount of crypto you are prepared to spend 'SUBNET': "community.3", # choose your subnet, currently this is the test network 'YAGNA_APPKEY': '<YOUR-YAGNA_APPKEY-GOES HERE>', # get this from `yagna app-key list` 'TIMEOUT': 120 # In seconds - you will need to figure this out for your workload. Max currently is 25min, so 25 * 60 seconds } ``` [Example](https://github.com/rogervs/cadcad_models/blob/2e61a84d1f28b23a3e0e9ef01f3c1f4fd4c85b2d/simple_cadcad.py#L75-L81) 3. Wrap your cadcad `Executor` in the cadcad Golem `Ambassador`: ``` Executor = Ambassador(Executor, golem_conf) ``` [Example](https://github.com/rogervs/cadcad_models/blob/2e61a84d1f28b23a3e0e9ef01f3c1f4fd4c85b2d/simple_cadcad.py#L83) For a simple Jupyter Notebook example, see [param_sweep.ipynb](https://github.com/rogervs/cadcadgolem/blob/master/param_sweep.ipynb) For a simple python script implementation, see [simple_cadcad.py](https://github.com/rogervs/cadcad_models/blob/master/simple_cadcad.py) ## System initialisation after first install 1. `yagna service run` 2. `yagna payment init -r` 3. Run your cadCAD code! ## cadCAD Examples/Demos You can find more cadCAD demos to play with here: https://github.com/cadCAD-org/demos To modify them them to work with cadcadGolem, just add the golem_conf dictionary declaration as above, and then wrap the cadCAD `Executor` with the cadCADGolem `Ambassador` and you're done. ## Security Notice The communication on the Golem network is currently not encrypted, so do not use this for any sensitive data. ## Caveats You need at least twice as many simulation runs as you have nodes, else it the simulation will fail.
