[Starpu-devel] MPI and fake handler

[Xavier Lacoste <xavier.lacoste@inria.fr>]

Hello,

I would like to know what information where required when submitting a task that will be executer on an other node.

For example :

node 1 possess A

node 2 possess B

the task is accessing A in read mode and B in write mode.

Then 1 don't have to know the size of the data B for example. He just has to know he needs to send A.

In this case can we use a fake handle for B (and all other data communicated from 1 to 2) with rank set to 2.

Is any other information required or is it safe to do with a fake handle ?

Regards,

XL.
