The datacenter networks we use today are based on a 50-year-old design. While it has served us well, that design no longer meets the needs of today's distributed applications. The result is failures visible to the users of those applications in spite

The fundamental problem of access control is to limit what a process can do to an object and when that process can do if. For example, any access control mechanism must know whether to honor a request to read or write a particular file. Unfortunately

The solution of the radiation transfer equation for the Earth's atmosphere needs to account for the reflectivity of the ground. When using the spherical harmonics method, the solution for this term involves an integral with a particular measure that

In his classic work on radiative transfer, Chandrasekhar introduced the discrete ordinates method for solving the integro-differential equation of radiative transfer; the spherical harmonics method is a spectral analog of this method. Not surprisingl

We present division and square root algorithm for calculations with more bits than are handled by the floating-point hardware. These algorithms avoid the need to multiply two high-precision numbers, speeding up the last iteration by as much as a fact
