Apptainer Build Process

Use the Slurm scheduler to request an interactive job on Flubber9

salloc -p rg-fpga --nodes=1 --ntasks-per-node=64 --mem=16G --nodelist flubber9 --time=01:00:00

Go to apptainer directory

$ pwd
vortex/miscs/apptainer

$  apptainer build --no-https vortex.sif vortex.def

To start the apptainer,

$ chmod +x run_apptainer.sh
$ ./run_apptainer.sh

| Note: Set env variables in run_apptainer.sh accordingly.

Inside the Apptainer,

# should show devices connected to machine on which you are running this command
Apptainer> lsusb

Vortex Simulation inside Apptainer

Go to bind of vortex repo,

Apptainer> cd /home/vortex
Apptainer> mkdir build
Apptainer> cd build
Apptainer> ../configure --xlen=32 --tooldir=$HOME/tools


Skip the below 3 steps, If tools are already present in the $HOME/tools
Apptainer> sed -i 's/\btar /tar --no-same-owner /g' ci/toolchain_install.sh
Apptainer> ./ci/toolchain_install.sh --all
Apptainer> sed -i 's/\btar --no-same-owner /tar /g' ci/toolchain_install.sh


Apptainer> source ./ci/toolchain_env.sh
Apptainer> verilator --version

Running SIMX, RTLSIM and XRTSIM

Compile the Vortex codebase
Apptainer> make -s

Run the programs by specifying the appropriate driver as shown below:

SIMX
Apptainer> ./ci/blackbox.sh --cores=2 --app=demo --driver=simx

RTLSIM
Apptainer> ./ci/blackbox.sh --cores=2 --app=demo --driver=rtlsim

XRTSIM
Apptainer> ./ci/blackbox.sh --cores=2 --app=demo --driver=xrt
