eisenmp multiprocess(or) example collection for server and mobiles

eisenmp_examples

Python 3.7 Multiprocess Framework for Server and Mobiles

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.

Inbuild example, assert a scrambled string. Use brute force or condensing.
We use an english (.6M) plus a german (2M) wordlist and make a dictionary of it. To gain more read speed.
(A) len(str) <=  11, combined brute force dictionary attack with a permutation generator. itertool prod. duplicates
    Permutation lists grow very fast, reaching Terabyte size.
(B) len(str) >=  12, pre reduce a len(str) list. Kick out words which are not matching char type and count.

eisenmp uses Pythons permutation generator itertools for the brute force attack example.

Another example downloads a large list and calculates 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.
