This paper gives an overview of the BlueGene/L Supercomputer. This is a jointly funded
research partnership between IBM and the Lawrence Livermore National Laboratory as part of …

… 2 is valid for any density p‘ provided … How likely is the event A to occur under such a p‘?
The probability … of A under p‘ does not depend on q, ie, A is not a rare event under p‘, …

This paper studies the estimation of the steady state mean of an output sequence from a
discrete event simulation. It considers the problem of the automatic generation of a confidence …

… of p(0) under quite general conditions. The use of classical spectral estimates to estimate p(0…
An entirely different approach which estimates p(0) by fitting an autoregressive model to { X(j…

The main interconnect of the massively parallel Blue Gene®/L is a three-dimensional torus
network with dynamic virtual cut-through routing. This paper describes both the architecture …

This paper develops efficient methods for computing portfolio value‐at‐risk (VAR) when the
underlying risk factors have a heavy‐tailed distribution. In modeling heavy tails, we focus on …

Software failures are now known to be a dominant source of system outages. Several studies
and much anecdotal evidence point to “software aging” as a common phenomenon, in …

… In BG/Q we will maintain the BG/L[1] and BG/P[2] system software philosophy of a simple
streamlined stack designed for scalability. The BG/Q system is optimized for applications that …

… To minimize Var(Ri), we should randomize between the two integers closest to 1/p, when
1/p itself is not an integer, choosing 1/p 1 with probability (1/p) mod 1 and 1/p with the …
