# AraSim CSE Spring 2024 Work

## Goals 
The main goal was to get a working multithreaded version of the AraSim codebase working. Doing this, the hope was to learn how to multithread the code and get it in a good place to hopefully also integrate GPU's at a later date.

## Where is it at currently? 
A bulk of the work done was to functionalize the Connect_Interaction_Detector_V2 to allow for multithreading and to cleanup codebase. 

### Going through code added/changed
Helper functions for multiple parts of code. They went through and split it up into multiple parts. Putting line numbers when needed

Part 1: Clearning Antenna Data
Part 2: Determine gain channel
Part 3: solve ray tracing (Not Done)
Part 4: Process Ray Tracing Solution (Not Done)
Part 5: Calculate Signal Factors (Not Done)
Part 6: Calculate Antenna Gain Factors (Not Done)
Part 7: Process Frequency Domain Signal
Part 8A: Process Neutrino Events. Lines 908 - 1208 (Not Done)
Part 8B: Process Arbitrary Events. Lines 1209 - 1475 
Part 8C: Process Simple Pulser Simulation. Lines 1478 - 1747 (Not Done)
Part 8D: Process PVA Pulser Simulation. Lines 1751 - 2110 (Not Done)
Part 8E: Process Calpulser Event. Lines 2113 - 2445
Part 9A: Process Noise. Lines 2593 - 2955
Part 9B: Process Trigger and Mimic Waveforms. Lines 2994 - 3624

## What still needs to be done? 
- Multithreading still isn't working, multiple threads are writing data to the same place causing the program to crash. This need to be resolved to at least have a working prototype. 

- I believe for multithreading we need to mark explicitly where file/data writing is happening to be able to adjust to make thread-safe

- Double checking that new functions are passing variables in the correct way. The CSE students had this has a slight fear. 

- Some helper functions are still not completed (3-6, 8A, 8C, 8D) 

- Current completed parts of code are all in separate branches and need to be merged after double checking that variable passing is correct
