“Job?” Submission Service

Objects:

• CompositeJob – has a one-to-one correspondence to “JDL” XML
• Request – object that contains the CompositeJob plus other info like email address for notification for example
• CompositeJobHandler – holds CompositeJob ID,

All non-Java objects are in a package like net.ppdg.cjhs

// This passes a request to service. The request contains

// a CompositeJob and extra information. This call

// returns an int ID to later refer to request.

int create (CJRequest request) throws CJHException

// Check to see if composite job can run, but doesn’t

// communicate with any other service.

// Maybe should return more complex type

// FeaturesNotSupportedList checkSupportedFeatures

boolean isRequestValid(int requestID) throws CJHException

// Actually runs or executes composite job is true and if false

// it asks service to analyze the time that composite job

// will take and maybe other information and returns

// a complex info object. Actually executes resource

// broker algorthm.

CJInfo submit(int requestID, boolean simulate) throws CJHException

// Gets overall global run information. Contains list of sub job IDs.

CJRunInfo getStatus(int requestID) throws CJHException

// Gets info on particular sub job, so that overall run info doesn’t have

// to go through each sub job and get info.
