ParallelObjective

ParallelObjective ( obj , DONOTUSECLIENT , NSubProblems , MaxSubReturn )

Set up MPI Client-Server support for objective optimization.

Parameters:

obj	Objective to parallelize
DONOTUSECLIENT	TRUE (default): client node does no object evaluation FALSE after putting servers to work Client node does one evaluation.
NSubProblems	integer, number of subproblems that can be done simultaneously.
MaxSubReturn	integer, longest vector returned by a subproblem

CstrServer

CstrServer :: CstrServer ( obj )

Execute

CstrServer :: Execute ( )

Do the objective evaluation. Receive structural parameter vector and Encode() it. Call vfunc().

Returns:: Nstruct (max. length of next expected message);

ObjClient

Execute

ObjClient :: Execute ( )

MultiParam

ObjClient :: MultiParam ( Fmat , aFvec , af )

obj

const decl obj [public]

Objective.

ObjClient

ObjClient :: ObjClient ( obj )

SubProblems

ObjClient :: SubProblems ( F )

Distribute subproblems of an objective across servers.

ObjServer

Execute

virtual ObjServer :: Execute ( )

Do the objective evaluation. Receive structural parameter vector and Encode() it. Call vfunc().

Returns:: Nstruct (max. length of next expected message);

Loop

virtual ObjServer :: Loop ( nxtmsgsz , calledby , update )

Wait on the objective client.

Parameters:

nxtmsgsz	integer, number of free parameters
calledby	string, where I'm coming from
update	TRUE, get announced new parameter vector after STOP

Nfree

decl Nfree [public]

Nstruct

decl Nstruct [public]

obj

const decl obj [public]

Objective.

ObjServer

ObjServer :: ObjServer ( obj )

SepServer

Execute

SepServer :: Execute ( )

Separable objective evaluations.

SepServer

SepServer :: SepServer ( obj )
