Detailed Description

AsctImpl - Implementation of the ASCT IDL interface.

AsctImpl implements ASCT interface. It also hosts methods for setting up the server side of the ASCT service (tasks such as ORB instantiation, proxy creation, etc). Finally, ASCT acts as a gatweway for remote execution requests, offering an interface that allows one to place execution requests to the GRM.

ASCT is a sigleton, because we are using threads and the only way to launch threads are via static methods. We could use other mechanisms to do that, but since we don't need more than one ASCT object, this solution is ok for now.

Member Function Documentation

void AsctImpl::acceptedExecutionRequest (  OfferSpecs  offSpecs  )  [inline]

Receive confirmation from a remote LRM that accepted our execution request Analog to 2k's "ACK" Parameters: offSpecs  - Offer information, see( See also: types::offSpecs)

void AsctImpl::acceptedExecutionRequest (  OfferSpecs  offSpecs  )

Called by a GRM to notify that one of our remote execution requests was accepted by a remote LRM. Parameters: offSpecs  - Information about the remote LRM that accepted our request See also: OfferSpecs

void AsctImpl::appFinished (  String  appId  )  [inline]

void AsctImpl::appFinished (  const string &  appId  )

Gets noticifation from a LRM that a given app has finished execution.

void AsctImpl::refusedExecutionRequest (  String  requestId  )  [inline]

Receive notice that one of our queries was rejected by all other LRMs (Though we can retry again if we so wish) Analog to 2k's "NACK" Parameters: requestId  - Id of the refused request

void AsctImpl::refusedExecutionRequest (  std::string  requestId  )

Called by a GRM to indicate that one of our remote execution requests wasn't accepted by any other LRM. In this case, we can take a variety of actions, such as retry the request or notify the user who submitted it. Parameters: requestId  - The id of the refused request

string AsctImpl::registerApplication (  string  appPath  )

Register an application on the ApplicationRepository Parameters: appPath  - A Valid patch to the applicatios Returns: an application id to be used in execution requests

BspInfo AsctImpl::registerBspNode (  String  appId, String  bspProxyIor )  [inline]

void AsctImpl::requestExecution (  ExecutionSpecs  execSpecs  )

Request execution Parameters: execSpecs  - describes the execution characteristics.

byte [] AsctImpl::requestInputFiles (  String  paths  )  [inline]

Receive request for files needed to allow the remote execution of a request made by this ASCT Parameters: paths  - the file path in the host where this ASCT is running Returns: all files needed by the remote execution Todo: : Signal error condition to caller(Raise CORBA exception) : Signal error condition to caller(Raise CORBA exception)

void AsctImpl::requestParametricExecution (  ParametricExecution  parExecSpecs  )

Request parametric execution Parameters: parExecSpecs  - describes the parametric execution characteristics.

void AsctImpl::returnOutputFiles (  String  appId, FileStruct[]  fileSequence )  [inline]
