Parser

Contents

1. ddex_schema - core of the project, it has all structs needed to deserialize xml
2. yaserde & yaserde_derive - dependencies of ddex_schema that were customized to support regex validation
3. validation_generator - generator used to generate... validation out of xml. Uses ts.
4. resources - sample ddex messages along with ern xml schema (stripped from descriptions and flattened)
5. runner - binary file to play around with the parser.

RUN Validation

1. Clone repo
2. cd parser
3. To run with CPU: cargo run --release
4. To run with GPU: cargo run --release -F cuda

Notes on GPU

Running on GPU requires a GPU with a lot of memory. We have tested it working on Nvidia cards with 8GB of RAM, but the more you have the better

On line 23 of /prover/host/src/main.rs you have the value .segment_limit_po2(19), which should work for cards with 8GB of RAM. For higher end cards (24GB) you can comment to entire line to improve performance. you can slighty modify this value to the maximum value that you system supports.

To run on GPU you might need to set these values first:

NVCC_APPEND_FLAGS='--gpu-architecture=compute_86 --gpu-code=compute_86,sm_86 --generate-code arch=compute_86,code=sm_86' 

Contents

1. core - shared interface between guest and host
2. host - 'main' code that is run by hardware. It creates environment for guest code to be proven and consists of logic what to do with generated receipt.
3. methods - in short, it consists guest code that is proven. Host 'records' execution of guest code. This is where xml parsing happends

Installation
