The SCOREC Core is a set of C/C++ libraries for unstructured mesh simulations on supercomputers. This project contains: * PUMI: parallel unstructured mesh infrastructure API User's Guide * PCU: Communication and file IO built on MPI * APF: Abstract definition of meshes, fields, and related operations * GMI: Common interface for geometric modeling kernels * MDS: Compact but flexible array-based mesh data structure * PARMA: Scalable partitioning and load balancing procedures * SPR: Superconvergent Patch Recovery error estimator * MA: Anisotropic mixed mesh adaptation and solution transfer * SAM: Sizing anisotropic meshes * STK: Conversion from APF meshes to Sandia's STK meshes * ZOLTAN: Interface to run Sandia's Zoltan code on APF meshes * PHASTA: Tools and file formats related to the PHASTA fluid solver * MTH: Math containers and routines * CRV: Support for curved meshes with Bezier Shapes * PYCORE: Python Wrappers * REE: Residual based implicit error estimator
