Detailed Description

Identical processors environment, the classifier is "P". All processors have unique speed and are therefore normalized to speed 1. Access the modifier in order to set properties.

Member Function Documentation

virtual void STypeInfo::assureInstanceOf (  const leda_string &    classifier )  const [pure virtual, inherited]

The same as isInstanceOf(), only that the program is stopped with an error in case of failure Parameters: classifier  e.g. "P", "Q", "R", etc

virtual leda_string STypeInfo::getClassifier (    )  [pure virtual, inherited]

Get the classifier of the object, using the classification scheme. E.g. "P" for Identical Processors Returns: classifier string

virtual SEnvironmentMod& SIdentical::getModifier (    )  [inline, virtual]

Get access to the modifier. Reimplemented from SUniform. Reimplemented in SBroadcast, and SSingle.

virtual int SIdentical::getNumOfMachines (    )  [inline, virtual]

Get the number of machines in this environment Returns: number of machines Reimplemented from SUniform. Reimplemented in SBroadcast, and SSingle.

virtual double SUnrelated::getRemProcTimeOn (  SJob &    job, const SMachines &    machines )  const [inline, virtual, inherited]

Get the time of how long a job will run on the machines in the same state. Precondition: The job must currently be scheduled on machines. Parameters: job  running job machines  reference to SMachines Returns: total processing time of job Implements SEnvironment. Reimplemented in SSingle.

virtual double SIdentical::getSpeed (  int    machine )  const [inline, virtual]

Get the speed of a specific machine. (Of course you will get speed 1.) Returns: speed of machine (=1) Reimplemented from SUniform. Reimplemented in SBroadcast.

virtual double SIdentical::getSpeed (  int    machine, const SJob &    job )  const [inline, virtual]

Get the speed of how fast a machine will process a job Parameters: machine  machine position. (Of course the speed is always equal to 1.) job  job Returns: speed (=1) Reimplemented from SUniform. Reimplemented in SBroadcast.

virtual const leda_matrix& SIdentical::getSpeedsMatrix (    )  const [inline, virtual]

Get the matrix containing the speed for a machine/job-pair. The rows correspond to machines, the columns to jobs. (Of course all speeds are equal to 1.) Returns: matrix containing speeds Reimplemented from SUniform. Reimplemented in SBroadcast.

virtual const leda_vector& SIdentical::getSpeedsVector (    )  [inline, virtual]

Get the vector with the speed-factor of the different machine. Respond to the question: How fast is a certain machine compared to the slowest machine ? (Of course here you will get all equal to 1.) Returns: the vector of speed-factors Reimplemented from SUniform. Reimplemented in SBroadcast.

virtual bool STypeInfo::isInstanceOf (  const leda_string &    classifier )  const [pure virtual, inherited]

Checks whether the object is an instance of the specified or a specialized class Parameters: classifier  e.g. "P", "Q", "R", etc Returns: true if the object can be casted to the specified class
