Many introduced plant species rely on mutualisms in their new habitats to overcome barriers to establishment and to become naturalized and, in some cases, invasive. Mutualisms involving animal-mediated pollination and seed dispersal, and symbioses between plant roots and microbiota often facilitate invasions. The spread of many alien plants, particularly(More)
Molecular dynamics simulations of a model main-chain liquid-crystalline polymer (LCP), and a low molecular weight analogue, have been carried out using an efficient parallel algorithm. A main-chain LCP is formed with the help of Gay-Berne mesogenic units connected to each other through flexible methylene spacers. We have studied the effect of varying the(More)
In this paper we evaluate the MPI environments currently available for Windows NT on the Intel IA32 and Compaq/DEC Alpha architectures. We present benchmark results for low-level communication and for the NAS Parallel Benchmarks to allow comparison to other systems, but our primary interest is determining real application performance and robustness in(More)
