"Recovery Act: SeaMicro Volume Server Power Reduction Research Development"
 Andrew Fetter (SeaMicro, Inc.), et al.
 Publication Date: 2012 Mar 22

"Recovery Act funding from the Department of Energy has helped SeaMicro's
 technologies enhance the total cost of operation, performance and energy
 efficiency in large data center and Cloud environments. SeaMicro's
 innovative supercompute fabric connects thousands of processor cores,
 memory, storage and input/output traffic. The company's fabric
 supports multiple processor instruction sets. ..."
"As a result of the Recovery Act funding from the U.S. Department of
 Energy, more than 50 direct jobs were created at SeaMicro. ..."

CHAPTER 1: SeaMicro Technology Overview
Dynamic Compute Allocation Technology (DCAT) (Page 13)
"DCAT adds a layer of intelligence to the distribution of work to
 the 512 CPUs by combining CPU management and stateful load balancing.
 The SeaMicro management software is aware of the health of, and
 the workload on, all the CPUs in the system. Based on this knowledge,
 the management software can transparently provision the CPUs and
 dynamically program the field programmable gate arrays (FPGAs)
 to direct traffic to one group of CPUs and away from another.
 The technology works by creating Virtual IP addresses which can
 be assigned to pools of compute as small as one server and as large as
 512 servers. The stateful hardware load balancer then distributes
 flows across these pools of servers using various load-management
 algorithms including round-robin, least connections, and max
 connections to enable the internal servers to be used effectively at
 the most optimal power consumption levels without degradation of
 end user performance. ..."

CHAPTER 2: Redundancy and Reliability Overview
I/O and Storage Cards (Page 15)
"Connecting to the fabric at multiple locations are the I/O and
 storage cards. The I/O and storage cards have a similar architecture.
 Both the I/O and the storage card contain two FPGAs and each FPGA
 connects to four different "ASICs" in the fabric. In the case of
 a FPGA link failure, the SeaMicro fabric routing automatically
 forwards traffic via one of the remaining three unaffected paths. ..."
