• Request

  public Request(mpjdev.Request req)

Method Detail

• Wait

  public Status Wait()
              throws MPIException

  Blocks until the operation identified by the request is complete.

  returns:

  status object

  Java binding of the MPI operation MPI_WAIT.

  After the call returns, the request object becomes inactive.

  Throws:

  MPIException

• Test

  public Status Test()
              throws MPIException

  Returns a status object if the operation identified by the request is complete, or a null reference otherwise.

  returns:

  status object or null reference

  Java binding of the MPI operation MPI_TEST.

  After the call, if the operation is complete (ie, if the return value is non-null), the request object becomes inactive.

  Throws:

  MPIException

• Testany

  public static Status Testany(Request[] r)
                        throws MPIException

  Tests for completion of either one or none of the operations associated with active requests.

  array_of_requests	array of requests
  returns:	status object or null reference

  Java binding of the MPI operation MPI_TESTANY.

  If some request completed, the index in array_of_requests for that request can be obtained from the returned status object through the. The corresponding element of array_of_requests becomes inactive. If no request completed, Testany returns a null reference.

  Throws:

  MPIException

• finalize

  public void finalize()
                throws MPIException

  Overrides:

  finalize in class java.lang.Object

  Throws:

  MPIException

• Is_null

  public boolean Is_null()
                  throws MPIException

  Test if request object is void.

  returns:

  true if the request object is void, false otherwise

  Throws:

  MPIException

• Waitall

  public static Status[] Waitall(Request[] r)
                          throws MPIException

  Blocks until all of the operations associated with the active requests in the array have completed.

  array_of_requests	array of requests
  returns:	array of status objects

  Java binding of the MPI operation MPI_WAITALL.

  The result array will be the same size as array_of_requests. On exit, requests become inactive. If the input value of arrayOfRequests contains inactive requests, corresponding elements of the result array will contain null status references.

  Throws:

  MPIException

• Waitany

  public static Status Waitany(Request[] r)
                        throws MPIException

  Blocks until one of the operations associated with the active requests in the array has completed.

  array_of_requests	array of requests
  returns:	status object

  Java binding of the MPI operation MPI_WAITANY.

  The index in array_of_requests for the request that completed can be obtained from the returned status object through the Status.index field. The corresponding element of array_of_requests becomes inactive.

  Throws:

  MPIException

• Testall

  public static Status[] Testall(Request[] r)
                          throws MPIException

  Tests for completion of all of the operations associated with active requests.

  array_of_requests	array of requests
  returns:	array of status objects

  Java binding of the MPI operation MPI_TESTALL.

  If all operations have completed, the exit value of the argument array and the result array are as for Waitall. If any operation has not completed, the result value is null and no element of the argument array is modified.

  Throws:

  MPIException

• Waitsome

  public static Status[] Waitsome(Request[] r)
                           throws MPIException

  Blocks until at least one of the operations associated with the active requests in the array has completed.

  array_of_requests	array of requests
  returns:	array of status objects

  Java binding of the MPI operation MPI_WAITSOME.

  The size of the result array will be the number of operations that completed. The index in array_of_requests for each request that completed can be obtained from the returned status objects through the Status.index field. The corresponding element in array_of_requests becomes inactive.

  Throws:

  MPIException

• Testsome

  public static Status[] Testsome(Request[] r)
                           throws MPIException

  Behaves like Waitsome, except that it returns immediately.

  array_of_requests	array of requests
  returns:	array of status objects

  Java binding of the MPI operation MPI_TESTSOME.

  If no operation has completed, TestSome returns an array of length zero and elements of array_of_requests are unchanged. Otherwise, arguments and return value are as for Waitsome.

  Throws:

  MPIException

• Cancel

  public void Cancel()
              throws MPIException

  Mark a pending nonblocking communication for cancellation. Java binding of the MPI operation MPI_CANCEL.

  Throws:

  MPIException
