I've got a question on the true operating Bandwidth of the CM-2

I am attaching to an 8k subset and using a 2-d mesh shape. If I use the

 CM_send_to_news(&input,output,0,CM_upward,boolsizeof(char));

exactly how many message startups will be executed. What I mean is that
If I have a 128x64 shape so I have 8K vitural processors on 8k physical
processors, and I send a message 8 bits long, do I actually produce
8 message startups. Is the true operating bandwidth in this case 1 bit?

Also, since 16 processors sit on a chip, and then there are 12 hypercube
wire interconnects going off chip, is a mesh embedded in the array, or
do the messages that go from one chip to the chip physically sitting next 
to it on the board go through hypercube routing (which in some cases
is longer that 1 unit route, right?).

thanks
