Cray makes XT3 supermachine
The supercomputer will be shipped to Japan Science and Technology Corp., JST. for testing various process emulation programs. Named Scalable Software Infrastructure (SSI), the project is meant for developing software libraries for massive parallel computing with a strong accent on scalability and compatibility.
XT3 is a scalable supercomputer of the 3rd generation based on AMD Opteron 100 processor nodes. Each node has its own RAM (1 to 8 GB ECC) and SeaStar comm module connected by HyperTransport that provides up to 7.6 Gbps connections over 6 channels. The architecture generally looks like this:
Physically, there are two processors elements (PE) per server blade. Blades are mounted into racks with interfaces to external network, storage, etc.
Linux-based OS is also of modular nature, each PE corresponds to a microcore, while from the higher levels the system is seen as a single whole or logical partitions. Development and management tools are based on the same principle.
