oxiida 0.1.0a2

A DSL for scientific workflow construction.

oxiida

oxiida is a workflow interpreter for building and controlling processes running on remote resources. It is opinioned on focusing at running scientific workflows in a high-throughput manner.

• oxiida supports construct and run tasks/jobs with different timespan from seconds to months.
• oxiida supports run tasks/jobs on local machine, cloud or HPC.
• oxiida has native support for Workflow Definition Language (WDL).
• oxiida as a language can embed into Python, Julia and Lua to powerup and standard your current workflow setup.

Construct workflow in Python

Similar as using the arithmetic, now I need to run a function (let's say I want to do high school match with math.sin(x), and a customize function to compute some nonsense stuff). And this function is defineded or imported in python. I can run it from Oxiida and also surpass the GIL!

import oxiida
import math
from time import sleep, time

def super_complex_operation(x: float, y: float, z: float) -> float:
    intermediate1 = math.sin(x) * math.log1p(abs(y))
    intermediate2 = math.exp(-z) + x ** 2
    # Sleep 2 sec to demostrat two of them can run concurrently without GIL limitation
    sleep(2);
    result = (intermediate1 + intermediate2) / (1 + abs(z - y))
    print("time:", time.strftime("%Y-%m-%d %H:%M:%S"))
    return result

# language = oxiida
workflow = """
require super_complex_operation;
require time, sleep;

para {
    print "--anchor--";
    seq {
        print(super_complex_operation(10, 3, 6));
    }

    seq {
        print(super_complex_operation(5.4, 3, 7));
    }
}
"""

if __name__ == '__main__':
    oxiida.run(workflow)

The powerfulness of running python function within Oxiida is you are not limited by the python GIL anymore. Using para block syntax allow to call both functions to run concurrently in separate threadings.

Disclaimer

The name comes from oxiida is the oxidized (it is rusty :crab:) AiiDA, the workflow engine my team are developing. It is not just another rewrite into rust project, instead I try to redesign it into a standard DSL.
