a workflow's execution in the end-user mode, respectively. As can be seen,
a progress bar is presented about the workflow's execution, so users can
follow their experiments' progress visually.
10.6 Execution Experiences and Performance
This section describes how the AutoDock workflows are actually executed
on cloud systems. Performance measurements show the possible optimi-
zations of the gateway back-end mechanism and the CBP to minimize the
execution time.
The selected application to perform the performance measurement was
the AutoDock Vina workflow, with the input set size of 8,500 ligands. The
measurements have been performed by distributing this input set among 25,
100, 250, and 1,000 jobs. Each scenario has been executed on the DG and the
cloud. Although we performed the measurements in the different scenarios,
we are only presenting our experiences with the 1,000-job scenario as the
others showed similar results. The measurements were conducted on the
SZTAKI Cloud with 25 virtual machines allocated for the experiments
and the EDGeS@home DG with variable and unpredictable active clients
(about 2,000 to 3,000 at a time) available.
