One in a million.
Thirty-six years ago, I was the first Cobra Pilot to shake the hand of a surviving Cobra Pilot who lost his tail rotor assembly while on a Hunter-Killer mission in South Vietnam. It was a hot, humid day at Quan Loi. I was an in-country trained Cobra maintenance officer for A Troop 3/ 17 Air Cav and Operation Lam Son 719 had been underway for weeks.

متن کاملMPI on a Million Processors
Petascale machines with close to a million processors will soon be available. Although MPI is the dominant programming model today, some researchers and users wonder (and perhaps even doubt) whether MPI will scale to such large processor counts. In this paper, we examine this issue of how scalable is MPI. We first examine the MPI specification itself and discuss areas with scalability concerns ...
متن کاملBuilding a Million Particle System
Particle systems have long been recognized as an essential building block for detail-rich and lively visual environments. Current implementations can handle up to 10,000 particles in realtime simulations and are mostly limited by the transfer of particle data from the main processor to the graphics hardware (GPU) for rendering. This paper introduces a full GPU implementation of both the simulat...
متن کامل50 Million Announced Forty Years Ago 100 Million Mexicans… Only
1% in 2000. Although the objective was far from being reached (the current rate being close to 2%), in 2000 Mexico had 53 million inhabitants fewer than it would have had if fertility had remained at its 1970 level. The population pyramids of 1930, 1970 and 2000 clearly illustrate this dynamics (Figure 2). In 1930 the population was beginning to recover from the aftereffects of the Revolution a...
متن کامل120 Million Agents Self-Organize into 6 Million Firms: A Model of the U.S. Private Sector
An agent model is described at full-scale with the U.S. private sector, consisting of some 120 million agents. Using data on the population of U.S. firms the model is calibrated to closely reproduce firm sizes, ages, growth rates, job tenure and labor flows, along with several other empirically-important facts. It consists of a coalition formation model in which the Nash equilibria are dynamica...
