CACT

A simple implementation of actor model in C, allowing only one system to work at the same time.

Example programs

n | ./silnia

Computes n! using the actor model in which actors calculate their part and then send the message with calculated data to the next actor.

./macierz

Runs a programme which accepts as input 2 integers a, b which represent dimensions of a matrix and after that 2ab integers representing consecutive values of matrix cells and times that simulate the time taken to compute certain values. For example:

2 3
4 1 2 1 7 1
10 20 30 40 50 60

Represents a matrix

  _ _ _ _ _ _ _   
| 4  | 2  | 7  |  
| 10 | 30 | 50 |  
  _ _ _ _ _ _ _

The programme after 1 + 1 + 1 ms will print 13 (4+2+7), and after next 20 + 40 + 60 ms will print 90 (10 + 30 + 50).

This example calculates row sums of given matrix by using b actors that send messeges with prefix sums to each other.
