Hi Josh, thak for your help !!
Is the use of the SparsePlaceGroup class scalable? I need the solution
to work with a large number of nodes.
I tried to make some like this:
var headersGroup:PlaceGroup = PlaceGroup.make(configNodes.numElems_1);
var explorersGroup:PlaceGroup = PlaceGroup.make(numExplorers);
val headNodes =
PlaceLocalHandle.make[CPLSNode(CPLSOptionsEnum.NodeRoles.HEAD_NODE as
Int)](headersGroup,() =>
NodeFactory.make(CPLSOptionsEnum.NodeRoles.HEAD_NODE as Int));
val explorersNodes =
PlaceLocalHandle.make[CPLSNode(CPLSOptionsEnum.NodeRoles.EXPLORER_NODE
as Int)](refsToPlaces, () =>
NodeFactory.make(CPLSOptionsEnum.NodeRoles.EXPLORER_NODE as Int));
I make this because i need instance diferent class in each PlaceGroup
(CPLSOptionsEnum.NodeRoles.EXPLORER_NODE or
CPLSOptionsEnum.NodeRoles.MASTER_NODE define the class). Then, i invoque
the correspond closure:
finish{
for(p in headersGroup) at (p) async{
headNodes().initialize();
}
}
finish{
for(p in explorersGroup) at (p) async{
explorersNodes().initialize();
}
}
But when i obtain the worker of each place, I see that some of the
places have the same worker:
Place(0)(Headers group). x10.lang.Runtime.Worker@0x1fd2a80
Place(1)(Headers group). x10.lang.Runtime.Worker@0x21e9d20
Place(0)(Explorers group). x10.lang.Runtime.Worker@0x1fd2a80
Place(1)(Explorers group). x10.lang.Runtime.Worker@0x21e9d20
Place(3)(Explorers group). x10.lang.Runtime.Worker@0x11b9d20
Place(2)(Explorers group). x10.lang.Runtime.Worker@0x1acbd20
Place(4)(Explorers group). x10.lang.Runtime.Worker@0x19a7d20
Thanks for your help,
Succes !!
