We examine the distribution and structure of human genetic diversity for 710 individuals representing 31 populations from Africa, East Asia, Europe, and India using 100 Alu insertion polymorphisms from all 22 autosomes. Alu diversity is highest in Africans (0.349) and lowest in Europeans (0.297). Alu insertion frequency is lowest in Africans (0.463) and(More)
Current day network processors incorporate several architectural features including symmetric multi-processing (SMP), block multi-threading, and multiple memory elements to support the high performance requirements of networking applications. We present an automated system-level design technique for application development on such architectures. The(More)

— The high performance requirements of networking applications has led to the advent of programmable network processor (NP) architectures that incorporate symmetric multi-processing, and block multi-threading. The paper presents an automated system-level design technique for process mapping on such architectures with an objective of maximizing the worst(More)
Network processor architectures incorporate block multi-threading to alleviate the performance degradation due to memory access latencies. Application design on such architectures requires the determination of the number of threads, and mapping of data items to the various memory elements such that the overall throughput is maximized. The paper presents a(More)
