Tools for performance monitoring and analysis become indispensable parts of programming environments for parallel computers. As the number of processors increases, the conventional techniques for monitoring the performance of parallel programs will produce large amounts of data in the form of event trace les. On the other hand, this wealth of information is a problem for the programmer who is f...
متن کاملAre there bushes in a forest?
In this paper we consider Markov processes in which the state at time t is & : Zd + (0, 1,2}. We think of 0 = grass, 1 = bushes, and 2 = trees, and formulate the evolution as follows: (i) l’s and 2’s each die (i.e. become 0) at rate 1. (ii) l’s (resp. 2’s) give birth at rate A, (resp. A,). (iii) If the birth occurs at x the offspring is sent to a site chosen at random from {y: y -x E X}, K = th...
متن کاملBushes in the Tree of Life
November 2006 | Volume 4 | Issue 11 | e352 Genome analyses are delivering unprecedented amounts of data from an abundance of organisms, raising expectations that in the near future, resolving the tree of life (TOL) will simply be a matter of data collection. However, recent analyses of some key clades in life’s history have produced bushes and not resolved trees. The patterns observed in these ...

متن کاملEnumerating Finite Racks, Quandles and Kei
A rack of order n is a binary operation B on a set X of cardinality n, such that right multiplication is an automorphism. More precisely, (X,B) is a rack provided that the map x 7→ x B y is a bijection for all y ∈ X, and (x B y) B z = (x B z) B (y B z) for all x, y, z ∈ X. The paper provides upper and lower bounds of the form 2cn 2 on the number of isomorphism classes of racks of order n. Simil...
