As it enters adolescence the Open Science Grid (OSG) is bringing a maturing
fabric of Distributed High Throughput Computing (DHTC) services that
supports an expanding HEP community to an increasingly diverse spectrum of
domain scientists. Working closely with researchers on campuses throughout
the US and in collaboration with national cyberinfrastructure initiatives,
we transform their computing environment through new concepts, advanced
tools and deep experience. We discuss examples of these including: the
pilot-job overlay concepts and technologies now in use throughout OSG and
delivering 1.4 Million CPU hours/day; the role of campus infrastructures-
built out from concepts of sharing across multiple local faculty clusters
(made good use of already by many of the HEP Tier-2 sites in the US); the
work towards the use of clouds and access to high throughput parallel
(multi-core and GPU) compute resources; and the progress we are making
towards meeting the data management and access needs of non-HEP communities
with general tools derived from the experience of the pariochial tools in
HEP (integration of Globus Online, prototyping with IRODS, investigations
into Wide Area Lustre).

We will also review our activities and experiences as HTC Service Provider
to the recently awarded NSF XD XSEDE project, the evolution of the US NSF
TeraGrid project, and how we are extending the reach of HTC through this
activity to the increasingly broad national cyberinfrastructure. We believe
that a coordinated view of the HPC and HTC resources in the US will further
expand their impact on scientific discovery.
