transforms need to be thus modified to ensure that ‘‘last digit’’ imprecision does
not end up dominating results.
Algorithm models, workflow representations, and recording provenance
information introduces overhead. Using the WND-CHARM workflow as an
example, OME overhead was found to be minimal (5% increase) as compared to
the algorithm execution time when executing the algorithms entirely outside of
OME. Provenance information can improve execution time when it is used
by the platform to distribute analysis across networked computers and to
reuse previous results, thus taking advantage of parallelization and avoiding
reexecuting algorithms with the same inputs.
Distributed Analysis Often when quantitative analysis is applied
to datasets with multiple ...
