Figure 2. Detailed work- and dataflow for co-phylogenetic analysis on the Grid
architecture of the client tool will be explained as
well as the integration with an existing middle-
ware toolkit.
An important design goal of the Grid-based
system for co-phylogenetic analyses was to re-use
the current graphical user interface of CopyCat
such that the deployment of Grid resources is
hidden from the end-user. One fundamental dif-
ference between the standard and Grid-enabled
versions of CopyCat (AxParafit) is that specific
Grid credentials are required (an X.509 user cer-
tificate) since Grid jobs can only be submitted by
authenticated and authorized users.
Overall Architecture
The basic workflow of a co-phylogenetic study
using CopyCat and the AxPcoords/AxParafit
programs has already been outlined in the above
section. Here, we will describe the architecture
