Hi @jmcarpenter2,

Dear Swifter Folks,

Recently, i found the speed when using swifter is 5-10x slower than using vanilla pandas apply for case that the process is not vectorized (my case is doing text preprocessing).

The experiment is like this:

import pandas as pd
import swifter

def clean_text(text):
    text = text.strip()
    text = text.replace(' ', '_')
    retu

Taking into consideration the purpose of max-parallel-commands it should be possible to override the value via a flag. In my case, depending on whether it's my laptop or CI server I might want to limit or raise the number of parallel executions to match my environment better. Having it in the file is not as flexible as I would expect...

Add 'Best Practices For Package Developers using Futures' vignette with instructions on, for instance,

1. How to test code, e.g. run tests with plan(sequential) and plan(multisession) and don't assume that plan(multicore) is available.

2. Make sure to shut down PSOCK clusters at the end of examples and package tests, i.e. call plan(sequential) at the end (e.g. #327)

3. Avoid setti

I am entering the subject as a non mathematician and non data scientist. I'm a potential user of your code who is looking to solve actual down to earth practical problems. While your code apparently beautifully includes a multitude of problems and algorithms, they are really wasted on me as I simply don't get the math, the lingo or the examples.

I therefore suggest you provide a few practical e

There should be at least a rough overview.

The Makefiles should define CXXFLAGS etc with ?= instead of = so that it doesn't matter if you set the variable on the left or right and side of the make invocation, i.e.:

VAR=val make
make VAR=val

What steps will reproduce the problem?
1. man pscp (or prsync or pslurp)
2. look in the NAME section

What is the expected output? What do you see instead?
expected (e.g.): pscp - parallel secure copy
see instead: parallel process kill program

What version of the product are you using?
2.3.1

On what operating system?
cygwin

Some problems/algorithms seem to have an inconsistent python exposition in terms of types.

For instance, in ../src/problems/dtlz.cpp we have:

dtlz::dtlz(unsigned prob_id, vector_double::size_type dim, vector_double::size_type fdim, unsigned alpha)

But in the ../pygmo/expose_problems_0.cpp it is exposed as:

dtlz_p.def(bp::init<unsigned, unsigned, unsigned, unsigned>

What do you propose?

The idea is to create a quick start document at the root of the repo, to illustrate how to quickly get started with JPPF, like an end-to-end HelloWorld. This would include how to setup and start a grid, full code example and expected output.

We shouldalso add a link to it in the main readme.md

What are the expected benefits and drawbacks?

The expectation is
