BatchTaskTemplate

Python scripts to manage parallelism and input resources for simulation tasks.

We will support or have supported these features:

  • Multiple GEM5 instances on single machine restoring from the Generic checkpoint for RISC-V
  • Multiple NEMU(private repo) instances on single machine restoring from the Generic checkpoint for RISC-V
  • Generate checkpoint by resuming from the nearest checkpoint with NEMU
  • Multiple Verilator simulation of Xiangshan instances on single machine restoring from the Generic checkpoint for RISC-V
  • Bug ''generation'', bug info gathering and VCD gathering for Xiangshan
  • Stats gathering for GEM5

We might support, but will not support in the near future:

  • Distributed version

Getting started

We use sh package to call simulators:

pip install sh

We will use GEM5 as an Example. We have a modified version of GEM5 here that supports current MMIO space and Generic Checkpoint. A full GEM5 tutorial can be found here.

Install dependency

First, install dependent packages.

For debian family:

sudo apt install gcc g++ python3 zlib1g-dev m4 libprotobuf-dev git swig python-dev protobuf-compiler libgoogle-perftools-dev libevent-dev make libncurses5-dev build-essential autoconf

If scons is 2.x on your machine, you can manually download scons 3 from sourceforge. Then expose the script to PATH in bashrc/zshrc/xxrc:

export PATH=/the/path/to/scons-3.1.2/src/script:$PATH

Note that scons is still the old scons, while scons.py is the newly installed one.

# Do to forget to source
source ~/.blablarc

build

cd /where/gem5/is/cloned
scons.py build/RISCV/gem5.opt -j 40

Wait a few minutes.

set executable, data, and script paths
