Slaves For Monte Carlo Example
The bad news is that we need four different slave programs, one for each
quadrant. The good news is that they are very simple and you have change only a
couple of lines to make the source for one quadrant into the source for
another.
The tasks all the slaves have to do.
- Generate two random numbers in the appropriate quadrant.
- Use the border relation for this quadrant to check if the point defines by
the two random numbers is inside the figure or not.
- If point is inside the figure increase a counter by one.
- Go back to step one until a set number of points has been checked.
- Sent the value of the counter back to the master.
- Ask master if there are more points to check for this quadrant,
- if yes, reset all variables and start over
- if no, exit
The only thing you have to change for the different versions of the slave
program is the range of the random numbers, so the points fall in the right
quadrant, and the relation which describes the border of the figure in this
quadrant.
