Description
Abstract: We describe a set of Web Services, created to support scientists in
performing distributed production tasks (e.g. Monte Carlo). The Web Services
described in this paper provide a portal for scientists to execute different
production workflows which can consist of many consecutive steps. The main design
goal of the Web Services discussed is to provide controlled access for (multiple)
set(s) of users in different roles (e.g. scientists, administrators, grid
operators,…) to complex production workflows without the added trouble of updating,
configuring, and patching these ever evolving applications and keep the users focused
on their core tasks (running production), while experts at the Tier2 centers keep the
software up to date. Once users execute a workflow they recieve a tracking number
that is used to track the job status which is propagated through MonALISA. Job
anomalies can be further investigated using the JobMon service.
The Web Services have been implemented inside the Clarens Web Service framework. This
Python (and Java) based framework provides, amongst others, x509 authorization,
access control and VO management for its services. The Web Services discussed in this
paper re-use several of these Clarens components in providing access control and
usage quotas. Initially the services described in this paper where developed to
support users in Monte Carlo production activities, however due to their generic
design, can be used to expose other (potentially complex) applications to users as
will be shown in this paper.
