Hello.
I tryed to write a function ParFilter. The function must filter a iterator by
boolean function. I’ve got a mistake.
gap> ParFilter([0..3],4,CheckNumbers);
master -> 1: [ 0, 0, 0, 0 ]
master -> 2: [ 0, 0, 0, 1 ]
master -> 3: [ 0, 0, 0, 2 ]
1 -> master: false
2 -> master: false
master -> 1: [ 0, 0, 0, 3 ]
master -> 2: [ 0, 0, 1, 0 ]
3 -> master: true
master -> 3: [ 0, 0, 1, 1 ]
1 -> master: true
2 -> master: false
Error, List Element: <list>[2] must have an assigned value in
called from
Sort( deltas );MasterSlaveDeadSlave( ); called from
TOPCmasterSendTaskInput( SubmitTaskInput, taskAgglomCount ) called from
TOPCmaster( SubmitTaskInput, CheckTaskResult, UpdateSharedData, taskAgglom
); called from
MasterSlave( function ( )
if IsDoneIterator( iterator ) then
return NOTASK;
else
return NextIterator( iterator );
fi;
return;
end, boolfnc, function ( input, output )
if output then
Add( result, input );
fi;
return NO_ACTION;
end, Error ); called from
CallFuncList( fnc, arg ) called from
... at line 3 of *stdin*
you can 'return;' after assigning a value
If need show a «deltas»
brk> deltas;
[ ,, 0 ]
I wrote the function ParFilter by example in ParGAP manual on pages 36-37.
If necessary, the file with my code. Function «CheckNumbers» is only example
function. I need to use other function. _______________________________________________
