C++14, New Solvers, I/O via openPMD API, HIP Support

This release switches to C++14 as minimum required version. Transition to C++17 is planned for upcoming releases.

We extended PIConGPU with a few new solvers. Binary collisions are now available. We added arbitrary-order FDTD Maxwell's solver. All field solvers are now compatible with perfectly matched layer absorber, which became default. Yee solver now supports incident field generation using total field/scattered field technique. We added Higuera-Cary particle pusher and improved compatibility of pushers with probe species. Implementation of particle boundaries was extended to support custom positions, reflecting and thermal boundary kinds were added.

With this release, PIConGPU fully switches to openPMD API library for performing I/O. The native HDF5 and ADIOS output plugins were replaced with a new openPMD plugin. All other plugins were updated to use openPMD API. Plugins generally support HDF5 and ADIOS2 backends of openPMD API, a user can choose file format based on their installation of openPMD API. We also added new plugins for SAXS and particle merging.

We added support for HIP as a computational backend. In particular, it allows running on AMD GPUs. Several performance optimizations were added. Some functors and plugins now have performance-influencing parameters exposed to a user.

The code was largely modernized and refactored, documentation was extended.

Perfectly Matched Layer (PML) and Bug Fixes

This release adds a new field absorber for the Yee solver, convolutional perfectly matched layer (PML). Compared to the still supported exponential dampling absorber, PML provides better absorption rate and much less spurious reflections.

We added new plugins for computing emittance and transition radiation, particle rendering with the ISAAC plugin, Python tools for reading and visualizing output of a few plugins.

The release also adds a few quality-of-life features, including a new memory calculator, better command-line experience with new options and bashcompletion, improved error handling, cleanup of the example setups, and extensions to documentation.

CPU Plugin Performance

This release fixes a performance regression for energy histograms and phase space plugins on CPU with our OpenMP backend on CPU. At least OpenMP 3.1 is needed to benefit from this. Additionally, several small documentation issues have been fixed and the energy histogram python tool forgot to return the first iteration.

Thanks to Axel Huebl, René Widera, Sebastian Starke, and Marco Garten for contributions to this release!

Changes to "0.4.1"

Bug Fixes:

  • Plugin performance regression:
    • Speed of plugins EnergyHistogram and PhaseSpace on CPU (omp2b) #2802

0.4.1

Date: 2018-11-06

Minor Bugs and Example Updates

This release fixes minor bugs found after the 0.4.0 release. Some examples were slightly outdated in syntax, the new "probe particle" EveryNthCell initialization functor was broken when not used with equal spacing per dimension. In some rare cases, sliding could occur twice in moving window simulations.

Thanks to Axel Huebl, René Widera, Richard Pausch and Andrei Berceanu for contributions to this release!

Changes to "0.4.0"

Bug Fixes:

  • PIConGPU:
    • avoid sliding twice in some corner-cases #2774

CPU Support, Particle Filter, Probes & Merging

This release adds CPU support, making PIConGPU a many-core, single-source, performance portable PIC code for all kinds of supercomputers. We added particle filters to initialization routines and plugins, allowing fine-grained in situ control of physical observables. All particle plugins now support those filters and can be called multiple times with different settings.

Particle probes and more particle initialization manipulators have been added. A particle merging plugin has been added. The Thomas-Fermi model has been improved, allowing to set empirical cut-offs. PIConGPU input and output (plugins) received initial Python bindings for efficient control and analysis.

User input files have been dramatically simplified. For example, creating the PIConGPU binary from input files for GPU or CPU is now as easy as pic-build -b cuda or pic-build -b omp2b respectively.

Thanks to Axel Huebl, René Widera, Benjamin Worpitz, Sebastian Starke, Marco Garten, Richard Pausch, Alexander Matthes, Sergei Bastrakov, Heiko Burau, Alexander Debus, Ilja Göthel, Sophie Rudat, Jeffrey Kelling, Klaus Steiniger, and Sebastian Hahn for contributing to this release!

0.3.2

Date: 2018-02-16

Phase Space Momentum, ADIOS One-Particle Dumps & Field Names

This release fixes a bug in the phase space plugin which derived a too-low momentum bin for particles below the typical weighting (and too-high for above it). ADIOS dumps crashed on one-particle dumps and in the name of on-the-fly particle-derived fields species name and field name were in the wrong order. The plugins libSplash (1.6.0) and PNGwriter (0.6.0) need exact versions, later releases will require a newer version of PIConGPU.

Changes to "0.3.1"

Bug Fixes:

  • PIConGPU:
    • wrong border with current background field #2326
  • libPMacc:
    • cuSTL: missing include in ForEach #2406
    • warning concerning forward declarations of pmacc::detail::Environment #2489
    • pmacc::math::Size_t<0>::create() in Visual Studio #2513
  • plugins:
    • phase space plugin: weighted particles' momentum #2428
    • calorimeter: validate minEnergy #2512
    • ADIOS:
      • one-particle dumps #2437
      • FieldTmp: derived field name #2461
    • exact versions of libSplash 1.6.0 & PNGwriter 0.6.0
  • tools:
    • tbg: wrong quoting of ' #2419
    • CMake: false-positive on in-source build check #2407
    • pic-configure: cmakeFlags return code #2323

Misc:

  • Hypnos (HZDR): new modules #2521 #2524

0.3.1

Date: 2017-10-20

Field Energy Plugin, Gaussian Density Profile and Restarts

This release fixes the energy field plugin diagnostics and the "downramp" parameter of the pre-defined Gaussian density profile. Restarts with enabled background fields were fixed. Numerous improvements to our build system were added to deal more gracefully with co-existing system-wide default libraries. A stability issue due to an illegal memory access in the PMacc event system was fixed.

Changes to "0.3.0"

.param file changes:

  • density.param: in Gaussian profile, the parameter gasSigmaRight was not properly honored but gasCenterRight was taken instead #2214
  • fieldBackground.param: remove micro meters usage in default file #2138

Bug Fixes:

  • PIConGPU:
    • gasSigmaRight of Gaussian density profile was broken since 0.2.0 release #2214
    • restart with enabled background fields #2113 #2139
    • KHI example: missing constexpr in input #2309
  • libPMacc:
    • event system: illegal memory access #2151
  • plugins:
    • energy field reduce #2112
  • tools:
    • CMake:
      • Boost dependency:
        • same minimal version for tools #2293
        • transient dependenciens: date_time, chrono, atomic #2195
      • use targets of boost & zlib #2193 #2292
      • possible linker error #2107
    • XDMF script: positionOffset for openPMD #2309
    • cmakeFlags: escape lists #2183
    • tbg:
      • --help exit with 0 return code #2213
      • env variables: proper handling of \ and & #2262

Misc:

  • PIConGPU: --help to stdout #2148
  • tools: all to C++11 #2194
  • documentation:
    • Hypnos .tpl files: remove passing LD_LIBRARY_PATH to avoid warning #2149
    • fix plasma frequency and remove German comment #2110
    • remove micro meters usage in default background field #2138
    • README: update links of docs badge #2144

0.3.0

Date: 2017-06-16

C++11: Bremsstrahlung, EmZ, Thomas-Fermi, Improved Lasers

This is the first release of PIConGPU requiring C++11. We added a newly developed current solver (EmZ), support for the generation of Bremsstrahlung, Thomas-Fermi Ionization, Laguerre-modes in the Gaussian-Beam laser, in-simulation plane for laser initialization, new plugins for in situ visualization (ISAAC), a generalized particle calorimeter and a GPU resource monitor. Initial support for clang (host and device) has been added and our documentation has been streamlined to use Sphinx from now on.

Changes to "0.2.0"

.param & .unitless file changes:

  • use C++11 constexpr where possible and update arrays #1799 #1909
  • use C++11 using instead of typedef
  • removed Config suffix in file names #1965
  • gasConfig is now density
  • speciesDefinition:
    • simplified Particles<> interface #1711 #1942
    • ionizer< ... > became a sequence of ionizers< ... > #1999
  • radiation: replace #defines with clean C++ #1877 #1930 #1931 #1937

Basic Usage:

We renamed the default tools to create, setup and build a simulation. Please make sure to update your picongpu.profile with the latest syntax (e.g. new entries in PATH) and use from now on:

  • $PICSRC/createParameterSet -> pic-create
  • $PICSRC/configure -> pic-configure
  • $PICSRC/compile -> pic-compile

See the Installation and Usage chapters in our new documentation on https://picongpu.readthedocs.io for detailed instructions.

0.2.5

Date: 2017-05-27

Absorber in z in 3D3V, effective charge in ADK ionization

The absorbing boundary conditions for fields in 3D3V simulations were not enabled in z direction. This caused unintended reflections of electro-magnetic fields in z since the 0.1.0 (beta) release. ADK ionization was fixed to the correct charge state (principal quantum number) which caused wrong ionization rates for all elements but Hydrogen.

Changes to "0.2.5"

Bug Fixes:

  • ADK ionization: effective principal quantum number nEff #2011
  • 3D3V: missing absorber in z #2042

Misc:

  • compile-time warning in 2D live plugin #2063
  • DeviceBufferIntern: fix shadowed member variable #2051
  • speciesInitialization: remove extra typename in doc #2044

Thanks to Marco Garten, Richard Pausch, René Widera and Axel Huebl for spotting the issues and providing fixes!

0.2.4

Date: 2017-03-06

Charge of Bound Electrons, openPMD Axis Range, Manipulate by Position

This release fixes a severe bug overestimating the charge of ions when used with the boundElectrons attribute for field ionization. For HDF5 & ADIOS output, the openPMD axis annotation for fields in simulations with non-cubic cells or moving window was interchanged. Assigning particle manipulators within a position selection was rounded to the closest supercell (IfRelativeGlobalPositionImpl).

Changes to "0.2.3"

Bug Fixes:

  • ionization: charge of ions with boundElectrons attribute #1844
  • particle manipulators: position offset, e.g. in IfRelativeGlobalPositionImpl rounded to supercell #1852 #1910
  • PMacc:
    • remove BOOST_BIND_NO_PLACEHOLDERS #1849
    • add missing HDINLINE #1825
    • CudaEvent: cyclic include #1836
  • plugins:
    • std includes: never inside namespaces #1835
    • HDF5/ADIOS openPMD:
      • GridSpacing, GlobalOffset #1900
      • ill-places helper includes #1846

Thanks to Axel Huebl, René Widera, Thomas Kluge, Richard Pausch and Rémi Lehe for spotting the issues and providing fixes!

0.2.3

Date: 2017-02-14

Energy Density, Ionization NaNs and openPMD

This release fixes energy density output, minor openPMD issues, corrects a broken species manipulator to derive density weighted particle distributions, fixes a rounding issue in ionization routines that can cause simulation corruption for very small particle weightings and allows the moving window to start immediately with timestep zero. For ionization input, we now verify that the number of arguments in the input table matches the ion species' proton number.

Changes to "0.2.2"

Bug Fixes:

  • openPMD:
    • iterationFormat only basename #1751
    • ADIOS trait for bool #1756
    • boundElectrons: non-weighted attribute #1808
  • RatioWeighting (DensityWeighting) manipulator #1759
  • MovingWindow: slide_point now can be set to zero #1783
  • energy density #1750 #1744 (partial)
  • possible NAN momenta in ionization #1817
  • tbg bash templates were outdated/broken #1831

Misc:

  • ConstVector:
    • check arguments init full length #1803
    • float to int cast warnings #1819
  • verify number of ionization energy levels == proton number #1809

Thanks to Axel Huebl, René Widera, Richard Pausch, Alexander Debus, Marco Garten, Heiko Burau and Thomas Kluge for spotting the issues and providing fixes!

0.2.2

Date: 2017-01-04

Laser wavepacket, vacuum openPMD & icc

This release fixes a broken laser profile (wavepacket), allows to use icc as the host compiler, fixes a bug when writing openPMD files in simulations without particle species ("vacuum") and a problem with GPU device selection on shared node usage via CUDA_VISIBLE_DEVICES.

Changes to "0.2.1"

Bug Fixes:

  • add missing minus sign wavepacket laser transversal #1722
  • write openPMD meta data without species #1718
  • device selection: guard valid range #1665
  • PMacc icc compatibility:
    • MapTuple #1648
    • AllCombinations #1646

Misc:

  • refactor InheritLinearly #1647

Thanks to René Widera and Richard Pausch for spotting the issues and providing fixes!

0.2.1

Date: 2016-11-29

QED synchrotron photon & fix potential deadlock in checkpoints

This releases fixes a potential deadlock encountered during checkpoints and initialization. Furthermore, we forgot to highlight that the 0.2.0 release also included a QED synchrotron emission scheme (based on the review in A. Gonoskov et al., PRE 92, 2015).

Changes to "0.2.0"

Bug Fixes:

  • potential event system deadlock init/checkpoints #1659

Thank you to René Widera for spotting & fixing and Heiko Burau for the QED synchrotron photon emission implementation!

0.2.0 "Beta"

Date: 2016-11-24

Beta release: full multiple species support & openPMD

This release of PIConGPU, providing "beta" status for users, implements full multi-species support for an arbitrary number of particle species and refactors our main I/O to be formatted as openPMD (see http://openPMD.org). Several major features have been implemented and stabilized, highlights include refactored ADIOS support (including checkpoints), a classical radiation reaction pusher (based on the work of M. Vranic/IST), parallel particle-IDs, generalized on-the-fly particle creation, advanced field ionization schemes and unification of plugin and file names.

This is our last C++98 compatible release (for CUDA 5.5-7.0). Upcoming releases will be C++11 only (CUDA 7.5+), which is already supported in this release, too.

Thank you to Axel Huebl, René Widera, Alexander Grund, Richard Pausch, Heiko Burau, Alexander Debus, Marco Garten, Benjamin Worpitz, Erik Zenker, Frank Winkler, Carlchristian Eckert, Stefan Tietze, Benjamin Schneider, Maximilian Knespel and Michael Bussmann for contributions to this release!

0.1.0

Date: 2015-05-21

This is version 0.1.0 of PIConGPU, a pre-beta version.

Initial field ionization support was added, including the first model for BSI. The code-base was substantially hardened, fixing several minor and major issues. Especially, several restart related issues, an issue with 2D3V zigzack current calculation and a memory issue with Jetson TK1 boards were fixed. A work-around for a critical CUDA 6.5 compiler bug was applied to all affected parts of the code.

Open Beta RC6

Date: 2014-11-25

This is the 6th release candidate, a pre-beta version.

Initial "multiple species" support was added for flexible particles, but is yet still limited to two species. The checkpoint system was refactored and unified, also incooperating extreme high file I/O bandwidth with ADIOS 1.7+ support. The JetsonTK1 development kit (32bit ARM host side) is now experimentally supported by PMacc/PIConGPU. The ZigZag current deposition scheme was implemented providing 40% to 50% speedup over our optimized Esirkepov implementation.

Open Beta RC5

Date: 2014-06-04

This is the 5th release candidate, a pre-beta version.

We rebuild our complete plugin and restart scheme, most of these changes are not backwards compatible and you will have to upgrade to libSplash 1.2+ for HDF5 output (this just means: you can not restart from a beta-rc4 checkpoint with this release).

HDF5 output with libSplash does not contain ghost/guard data any more. These information are just necessary for checkpoints (which are now separated from the regular output).
