Method Detail

calculateBatchQueueQuality

public static float calculateBatchQueueQuality(int runningJobs,
                                               int waitingJobs)

Calculate the quality of a Batch Queue resource, such as PBS and LSF.

Parameters:

runningJobs - The number of running jobs in all queues.

waitingJobs - The number of waiting jobs in all queues.

Returns:

The quality as float number between 0 and 1.

calculateWaittimeQuality

public static float calculateWaittimeQuality(float queueWaittime)

Calculate the quality of a PBS resource that supports waiting time estimation.

Parameters:

queueWaittime - The estimated queue waiting time in minutes

Returns:

The quality as float number between 0 and 1.

calculateForkQuality

public static float calculateForkQuality(int load,
                                         int cpus)

Calculate the quality of a Fork resource.

Parameters:

load - The load of the resource (as defined in the linux program "top").

cpus - The number of cpus.

Returns:

The quality as float number between 0 and 1.
