= ANL ITAPS project =

== Goals ==
''The [http://www.itaps.org/ ITAPS center] is a collaboration between several universities and DOE laboratories, and is funded by the DOE [http://www.scidac.gov/ SciDAC] program.  The primary objective of ITAPS is to develop technologies that enable application scientists to easily use multiple mesh and discretization strategies within a single simulation on petascale computers.  This is accomplished through the development of common functional interfaces to geometry, mesh, and other simulation data.  This web site describes ANL’s implementation of these interfaces.''

== [http://www.itaps.org/software/ Interfaces]: == 
ITAPS is developing interface specifications for geometry ([http://www.itaps.org/software/download_interfaces.html iGeom]), mesh ([http://www.itaps.org/software/download_interfaces.html iMesh]), and relations ([http://www.itaps.org/software/download_interfaces.html iRel]), which are used to access various data used in petascale applications.

== Implementations & Downloads: ==
ANL is working on implementations of the ITAPS interfaces.  iGeom and iMesh are implemented in the [wiki:CGM CGMA] and [wiki:MOAB MOAB] packages, respectively.  iRel is implemented in the newer [wiki:Lasso Lasso] component. 

== Services & Applications: == 
ANL's ITAPS interface implementations and the components they rely on have been used to implement various services and applications, including [http://www.cs.sandia.gov/optimization/knupp/Mesquite.html Mesquite], DDRIV, MBZoltan, Camel, and partGeom.
