Multithreaded transactions in scientific computing: New versions of a computer program for kinematical calculations of RHEED intensity oscillations

Abstract
Writing a concurrent program can be more difficult than writing a sequential program. Programmer needs to think about synchronisation, race conditions and shared variables. Transactions help reduce the inconvenience of using threads. A transaction is an abstraction, which allows programmers to group a sequence of actions on the program into a logical, higher-level computation unit. This paper presents multithreaded versions of the GROWTH program, which allow to calculate the layer coverages d...

Title of program: GROWTHgr, GROWTH06
Catalogue Id: ADVL_v2_0

Nature of problem
The programs compute the RHEED intensities during the growth of thin epitaxial structures prepared using the molecular beam epitaxy (MBE). The computations are based on the use of kinematical diffraction theory [1].
