Every process (knight) in distrubuted system requests one of available resources (windmills) but only 4 of them are allowed to use the resource simultaneously. Every process goes in loop:

• it request access to critical section
• stays in critical section for random time
• releases critical section and waits for a random time
  Only 4 processes are allowed to be in critical section at the same time.

Code is implementation of modified Lamport algorithm written in OpenMPI .

When running the application you need to pass number of available resources as parameter.
