	The very largest parallel particle simulations, for problems involving six dimensional phase space and field data, generate vast quantities of data. It is desirable to store such enormous data-sets efficiently and also to share data effortlessly between other programs and analysis tools. With H5Part we defined a very simple file schema built on top of HDF5 (Hierarchical Data Format version 5) as well as an API that simplifies the reading and writing of the data to the HDF5 file format. Our API, which is oriented towards the needs of the particle physics and cosmology community, provides support for three types of common data types: particles, structured and unstructured meshes. HDF5 offers a self-describing machine-independent binary file format that supports scalable parallel I/O performance for MPI codes on computer systems ranging from laptops to supercomputers. The following languages are supported: C, C++, Fortran and Python. We show the easy usage and the performance for reading/writing terabytes of data on several parallel platforms. H5part is being distributed as Open Source under a BSD-like license.

	Funding: Supported in part by the US DOE, Office of Science, SciDAC program; Office of High Energy Physics; Office of Advanced Scientific Computing Research MaryLie/IMPACT (ML/I) is a 3D parallel Particle-In-Cell code that combines the nonlinear optics capabilities of MaryLie 5.0 with the parallel particle-in-cell space-charge capability of IMPACT. In addition to combining the capabilities of these codes, ML/I has a number of powerful features, including a choice of Poisson solvers, a fifth-order rf cavity model, multiple reference particles for rf cavities, a library of soft-edge magnet models, representation of magnet systems in terms of coil stacks with possibly overlapping fields, and wakefield effects. The code allows for map production, map analysis, particle tracking, and 3D envelope tracking, all within a single, coherent user environment. ML/I has a front end that can read both MaryLie input and MAD lattice descriptions. The code can model beams with or without acceleration, and with or without space charge. Developed under a US DOE Scientific Discovery through Advanced Computing (SciDAC) project, ML/I is well suited to large-scale modeling, simulations having been performed with up to 100M macroparticles. ML/I uses the H5Part* library for parallel I/O. The code inherits the powerful fitting/optimizing capabilities of MaryLie, augmented for the new features of ML/I. The combination of soft-edge magnet models, high-order capability, and fitting/optimization, makes it possible to simultaneously remove third-order aberrations while minimizing fifth-order, in systems with overlapping, realistic magnetic fields. Several applications will be presented, including aberration correction in a magnetic lens for radiography, linac and beamline simulations of an e-cooling system for RHIC, design of a matching section across the transition of a superconducting linac, and space-charge tracking in the damping rings of the International Linear Collider. *ICAP 2006 paper ID 1222, A.
