For x86 architectures, the most I'm seeing in any available motherboard is 12 DIMMs per socket with current dual socket offerings that go to 768GB (384GB per socket, 32GB per DIMM slot). However if you go to ark.intel.com and check out the E7-4xxx it shows that it can address up to 2TB of memory and the E7-8xxx can address up to 4TB of memory. So with either of these solutions, to maximize the total amount of memory that any one processor could see in a board filled with all CPU sockets, you'd need at least 512GB per socket (4 socket solution for the E7-4xxx and 8 socket for the E7-8xxx), I just don't see that anyone has made such a motherboard yet. _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
