eisenmp-examples 0.5.1

eisenmp multiprocess(or) example collection for server

Python 3.7 Multiprocess Framework for single Server

Examples:

• simple style prime number calculation to see the basic use

• simple http server on one cpu gets content via queue

• one flask orm server on each cpu - share a user db

• multiple flask orm server on each cpu, port groups - share a user db

• web download csv large list, calculate average over a column

• brute_force_attack with itertools generator and dictionary

• example with two, double fed queues

• All scenarios follow the Template style and have descriptions

## How to run the examples?

1. Clone the repo and run an eisenmp_exa_... or

2. Install PyPi package

• in terminal run: eisenmp_url and open the local Python SimpleHTTP URL

• in terminal run: eisenmp_menu and choose from Menu

Brute force cracks strings of an online-game alphabet salad quest.

Brute Force

We use an english (.6M) plus a german (2M) wordlist and make a dictionary of it. To gain more read speed.

len(str) <= 11, combined brute force dictionary attack with a permutation generator. itertool prod. duplicates Permutation lists grow very fast, reaching Terabyte size.

len(str) >= 12, pre reduce a len(str) list. Kick out words which are not matching char type and count.

Web download a large list

Calculates the average for one column. Python CSV extracts the column and we calculate the average with the assigned number of Porcesses/CPU cores. It can be more processes than CPU cores, if it makes sense.
