beowulf

Earlier Versions

beowulf version 1.0

Version 1.0 is available. This is the version used to produce the results in Phys. Rev. D62, 014009 (2000), hep-ph/9910292. As far as I know, version 1.0 is free of bugs. However, version 1.1 is a bit faster.

There are two program files. The top level routines in beowulf.f can be easily modified by the user to calculate any three-jet-like infrared safe quantity or to change some of the parameters that the program uses. The subrountines in beowulfsubs.f should not be modified.

The top level routines, beowulf.f version 1.0.
The subroutines, beowulfsubs.f version 1.0.
Usage notes version 1.0.
Technical notes on the algorithms used (Postscript file), version 1.0

beowulf version 0.7

This is the version used to produce the results in Phys. Rev. Lett. 81, 2638 (1998), hep-ph/9804454 and is retained here for archival purposes. Beware: there is a bug in beowulf version 0.7. The error is in the logic of the routines for choosing Monte Carlo points. It had the result that in some regions of momentum space the calculated density of points did not match the actual density of points. This led to discrepancies of 1% to 2% in the results. I thank M. Seymour and Z. Kunszt for providing results that helped me find problem. The deficiency is corrected in version 1.0, available under the preceding heading.
