Hi!

I saw at the apple site that each processor have 6.4GB/sec bandwith to each memory bank.
How can i utilitize this ?
I wrote a small test program, and i can get 6.1GB/sec with one process, this is great, but when I use 2 then I get 3.8GB/sec for each.

Is it possible to "assign" a processor and a bank to a thread ?

You can't get 12.8GB/sec. Each processor has a 6.4GB/sec link, but the memory only has a single 6.4GB/sec link (or rather two 3.2GBs/sec links).

You are right. I have reread the doc and it is the case.
