Message:

Major evolution of the malloc library, to provide two new services:

• all allocated blocks are aligned, and the size is a power of 2.
• the remote-malloc() function allows the application to explicitely define the cluster(x,y).

We keep only the close-fit allocation policy.
These services were required to implement the distributed SBT barrier.
