PoolFlow

A simple process management library

Introduction

PoolFlow provides simple objects to manage the execution of a variety of tasks and its memory usage. The main objective of PoolFlow is to perform a lot of scientific calculations and manage their successive executions through the subprocess library.

Schematic principle

The way PoolFlow works could be synthesized by the following diagram. A list of jobs is given and the pool object manage the available virtual memory, considering the maximum estimated cost of the job given by the user.

graph LR
A[Job with<br>given cost]-->|Set of parameters|B{Pool};
B-->C[Estimated usage<br>memory];
C-->|Not enough<br>memory|B;
C-->|Memory available<br>and allocated|D[Job is<br>launched];
D-->|Job is done<br>memory est released|B;

Installing

The only external package SourceFlow depends on is rich. Install it directly via pip:

pip install PoolFlow
