Hi Konstantina,
a more general version of collecting finish / offers is proposed, called
'accumulator variables', but this is not yet fully implemented.
Collecting finish should work fine in X10 2.3.
The Reducible interface is in x10.lang. It includes a generic
SumReducer struct type that you could use instead of the Double-specific
one I posted.
Can you post the code that is causing the error, along with the compile
error that you receive?
Cheers,
Josh

Hello again,
I tried to restructure my code according to the example..
The problem is that I get errors with the SumReducer struct (the
errors point to the java generated code, and can't really make sense)
I checked the specification for v2.3. and found this:
offers. The offers concept was experimental in 2.1, but was determined
inadequate. It has not been removed from the compiler yet, but it will
be soon. In
the meantime, traces of it are still visible in the grammar. They
should not be
used and can safely be ignored
Also I cannot track the Reducible interface in the API.
Is there any other more explicit way to reduce values from different
places?
Thanks again,
Konstantina

Thanks a lot for the useful feedback.
Although, I did not expect I would need such low level
tuning. Looks a lot like MPI.
X10 is a procedural programming language for distributed
programming where the notions of concurrency and distribution
are made explicit.
It is closer to MPI than, say, a more limited, declarative
language with implicit concurrency, in which the compiler
determines run-time concurrency and distribution (e.g. ZPL).
We are very interested in such (declarative) languages as
well, and building them on top of X10, in the long term.
