A quickstart guide to run Linux on Arty A7 100T FPGA

Because everyone keeps posting about Arty A7 35T while I only have the 100T. This is basically just a guide for linux on litex [https://github.com/litex-hub/linux-on-litex-vexriscv].

Requirements

• Arty A7 100T FPGA
• Micro USB Cable
• and a PC

# This is a modified version of TRL's `SFTTrainer` example (https://github.com/huggingface/trl/blob/main/examples/scripts/sft_trainer.py), 
# adapted to run with DeepSpeed ZeRO-3 and Mistral-7B-V1.0. The settings below were run on 1 node of 8 x A100 (80GB) GPUs.
#
# Usage:
#   - Install the latest transformers & accelerate versions: `pip install -U transformers accelerate`
#   - Install deepspeed: `pip install deepspeed==0.9.5`
#   - Install TRL from main: pip install git+https://github.com/huggingface/trl.git
#   - Clone the repo: git clone github.com/huggingface/trl.git
#   - Copy this Gist into trl/examples/scripts
#   - Run from root of trl repo with: accelerate launch --config_file=examples/accelerate_configs/deepspeed_zero3.yaml --gradient_accumulation_steps 8 examples/scripts/sft_trainer.py

HTTPS, FTPS, and Benchmark Explanation

HTTPS Handshake Log Explanation

We demonstrate the HTTPS connection between two Raspberry Pi. The HTTPS client is using our cryptochip that will do the handshake and connect to the ordinary HTTPS server. This shows that our cryptochip works flawlessly and compatible with other widely used crypto library.

Server started, CA certificate, server certificate and key loaded.
