This Portable Common Lisp version for the Cray couples the language's strengths with the machine's power. The researchers who developed the implementation tell how they did it.

Constants with formulae of the form treated by D. Bailey, P. Borwein, and S. Plouffe (BBP formulae to a given base b) have interesting computational properties, and there are hints that they should… (More)

We describe a “dissected” sieving algorithm which enumerates primes in the interval [x1, x2], using O(x 1/3 2 ) bits of memory and using O(x2 − x1 + x 2 ) arithmetic operations on numbers of O(lnx2)… (More)

Portable Standard Lisp (PSL), a dialect of Lisp developed at the University of Utah, has been implemented and optimized for the Cray 1 and Cray X-MP supercomputers. This version uses a new… (More)

The methods presently available for measuring FRC of newborn infants are impractical and used primarily as research tools. This report describes a new device for estimating FRC which is accurate,… (More)

Constants with formulae of the form treated by D. Bailey, P. Borwein, and S. Plouffe (BBP formulae to a given base b) have interesting computational properties, such as allowing single digits in… (More)

The Twin Prime Conjecture is a difficult unsolved problem in number theory; it states that there are infinitely many primes p such that p+2 is also prime. This is a special case of a more general… (More)
