No Scatter for new CommunicationGroupDriver ??

[ks881115]

Now I'm trying to implement my algorithm using new communication method introduced by BroadcastREEF.

However, I found out that no addScatter method in CommunicationGroupDriver which means I have to redundantly broadcast all data.

Is there anyone who knows how to add scatter for new CommunicationGroupDriver?? or would it be OK to broadcast whole dataset?

You should be able to load data into Compute Tasks without having to broadcast all of the data, using the Data Loading API.

I used GroupOperator and there's addScatter method exist. You can find it in MatMul example. https://github.com/Microsoft-CISL/shimoga/tree/master/src/main/java/com/microsoft/reef/examples/groupcomm/matmul

But our course instruction ( https://sites.google.com/site/snubdcsfall2014/programming-assignment/elastic-group-communication-api) is recommending us to use new group communication method instead of the old one (GroupOperator). Thanks for reply though
