Very interesting stuff here. This is one of the first next generation super computer architectures to address the bottleneck in the shared memory, file IO space, and it does so in a big way. You can really see the power of SSD's coming alive.
We could also see the emergence of 'specialized' nodes. Currently, all of the nodes of a supercomputer are generally identical (same amount of memory, processors, interconnects, cores, etc.) In a few years we could see architectures that house node clusters that excel at certain tasks. For example, a cluster of nodes that has a large amount of GPU acceleration emphasizing visual computing / vector processing, another cluster of nodes that specializes in scalar processing of tasks that aren't easily parralized, another cluster of nodes like 'Gordon's' that specializes in getting the info in and out of the storage array and to the other parts at a much faster rate.
Your thoughts?
When fully configured and deployed in 2011, Gordon will feature 245 teraflops of total compute power (one teraflop or TF equals a trillion calculations per second), 64 terabytes (TB) of DRAM (digital random access memory), 256 TB of flash memory, and four petabytes of disk storage (one petabyte or PB equals one quadrillion bytes of data.)
The new supercomputer's key feature will be 32 "supernodes" based on the latest Intel Xeon Processors available in 2011 combined with several state-of-the-art technological innovations to include virtual shared-memory software. Using virtual shared-memory software, each of the system's 32 supernodes has the potential of 7.7 TF of power and 10 TB of memory (2 TB of DRAM and 8 TB of flash memory). The supernodes will be interconnected via an InfiniBand network, capable of 16 gigabits per second of bi-directional bandwidth -- that's eight times faster than some of the most powerful national supercomputers to come on-line in recent months.
