scheduling-simulator's Introduction

SCHEDULING SIMULATOR

Scheduling simulator is a Advanced Operating System assignment which requires to implement a simulator of different scheduling algorithm.

Current supported scheduler:

Short job first.
Round Robin.
Rate monotonic.
Earliest deadline first.
Lottery scheduling.

How to build it?

Dependencies

For developers

Autotools suite.
Python3 with yaml module (For integration tests).

For users

UNIX plataform.
C++ compiler with c++14 support.

Building it

The project uses Autotools. Thus, the building steps are the common three steps to build:

#Download the tar ball from Github.
wget https://github.com/vicentebolea/scheduling-simulator/releases/download/v0.0.2/scheduling-simulator-0.0.2.tar.gz

#untar
tar xf scheduling-simulator-0.0.2.tar.gz

# configure the project
cd scheduler..
./configure --prefix `pwd`/build

# Optional, check the unit tests
make check

# Compile and install it
make install

How to run it?

The binary called scheduler_sim will be installed in the prefix/bin folder. Here are the different options that scheduler_sim supports:

simulator_sim -s SCHEDULER [OPS] -i FILE
    -s SCHEDULER: SJF,RR,RM,EDF,LT
    -i FILE:      If file is -, it will read the input from stdin
    [OPS]: 
      -q #:         Quantum (For RR and LT).
      -e #:         Ending time (For RM and EDF).
      -f:           For LT to use most probable proccess.

make check error

When I run make check I get the following error:

stdin_reader.cc: In member function ‘virtual std::vector<std::__cxx11::basic_string<char> > scheduler_simulator::StdinReader::next()’:
