To parallelize, say, ./evaluation/intro/hello-world.sh with parallelization degree of 2× run:
./pa.sh ./evaluation/intro/hello-world.shRun ./pa.sh --help to get more information about the available commands.
Jump to docs/tutorial for a longer tutorial.
On Ubuntu, Fedora, and Debian run the following to set up PaSh.
wget https://raw.githubusercontent.com/binpash/pash/main/scripts/up.sh
sh up.sh
export PASH_TOP="$PWD/pash/"
## Run PaSh with echo hi
"$PASH_TOP/pa.sh" -c "echo hi"For more details, manual installation, or other platforms see installation instructions.
This repo hosts the core pash development. The structure is as follows:
- compiler: Shell-dataflow translations and associated parallelization transformations.
- docs: Design documents, tutorials, installation instructions, etc.
- evaluation: Shell pipelines and example scripts used for the evaluation.
- runtime: Runtime component — e.g.,
eager,split, and associated combiners. - scripts: Scripts related to continuous integration, deployment, and testing.
