A condition should be also added on the number of SubGroups. NumTilesPerGroup > NumSubGroups.

Could we represent the wfi as a multi-dimensional packed array at least on the cluster dimension? This would make the code more readable. This comment is also valid for follwoing signals indexed over the cluster dimension.

It could be useful to add a barrier function for the synchronization of a single cluster. Are clusters bounded to work all in parallel on the same task at the moment?

This PR extends MemPool to support multiple clusters. It mainly addresses the hardware side and the basic corresponding software changes. Updating the kernels to multi-cluster kernels will be done in a second step.
Depends on #113 and #114
