| 4 | +0.1.0 |
| 5 | +----- |
| 6 | +**Date:** 2015-05-21 |
| 7 | + |
| 8 | +This is version `0.1.0` of PIConGPU, a *pre-beta* version. |
| 9 | + |
| 10 | +Initial field ionization support was added, including the first model for BSI. |
| 11 | +The code-base was substantially hardened, fixing several minor and major |
| 12 | +issues. Especially, several restart related issues, an issue with 2D3V zigzack |
| 13 | +current calculation and a memory issue with Jetson TK1 boards were fixed. |
| 14 | +A work-around for a critical CUDA 6.5 compiler bug was applied to all affected |
| 15 | +parts of the code. |
| 16 | + |

| 71 | + |
| 72 | +**Bug Fixes:** |
| 73 | + - CUDA 6.5: `int(bool)` casts were broken (affects plugins |
| 74 | + `BinEnergyParticles`, `PhaseSpace` and might had an effect on methods of the |
| 75 | + basic PIC cycle) #570 #651 #656 #657 #678 #680 |
| 76 | + - the ZigZag current solver was broken for 2D3V if non-zero |
| 77 | + momentum-components in z direction were used (e.g. warm plasmas or |
| 78 | + purely transversal KHI) #823 |
| 79 | + - host-device-shared memory (SoC) support was broken (Jetson TK1) #633 |
| 80 | + - boost 1.56.0+ support via `Resolve<T>` trait #588 #593 #594 |
| 81 | + - potential race condition in field update and pusher #604 |
| 82 | + - using `--gridDist` could cause a segfault when adding additional arguments, |
| 83 | + e.g., in 2D3V setups #638 |
| 84 | + - `MessageHeader` (used in `png` and 2D live visualization) leaked memory #683 |
| 85 | + - restarts with HDF5: |
| 86 | + - static load-balancing via `--gridDist` in y-direction was broken #639 |
| 87 | + - parallel setups with particle-empty GPUs hung with HDF5 #609 #611 #642 |
| 88 | + - 2D3V field reads were broken (each field's z-component was not initialized |
| 89 | + with the checkpointed values again, e.g., `B_z`) #688 #689 |
| 90 | + - loading more than 4 billion global particles was potentially broken #721 |
| 91 | + - plugins: |
| 92 | + - `Visualization` (png & 2D live sim) memory bug in double precision runs #621 |
| 93 | + - `ADIOS` |
| 94 | + - storing more than 4 billion particles was broken #666 |
| 95 | + - default of `adios.aggregators` was broken (now = MPI_Size) #662 |
| 96 | + - parallel setups with particle-empty GPUs did hang #661 |
| 97 | + - `HDF5`/`ADIOS` output of grid-mapped particle energy for non-relativistic |
| 98 | + particles was zero #669 |
| 99 | + - libPMacc: |
| 100 | + - CMake: path detection could fail #796 #808 |
| 101 | + - `DeviceBuffer<*,DIM3>::getPointer()` was broken (does not affect |
| 102 | + PIConGPU) #647 |
| 103 | + - empty super-cell memory foot print reduced #648 |
| 104 | + - `float2int` return type should be int #623 |
| 105 | + - CUDA 7: |
| 106 | + - cuSTL prefixed templates with `_` are not allowed; usage of static dim |
| 107 | + member #630 |
| 108 | + - explicit call to `template`-ed `operator()` to avoid waring #750 |
| 109 | + - `EnvironmentController` caused a warning about `extendend friend syntax` #644 |
| 110 | + - multi-GPU nodes might fail to start up when not using `default` compute |
| 111 | + mode with CUDA 7 drivers #643 |
| 112 | + |
| 113 | +**Misc:** |
| 114 | + - HDF5 support requires libSplash 1.2.4+ #642 #715 |
| 115 | + - various code clean-up for MSVC #563 #564 #566 #624 #625 |
| 116 | + - plugins: |
| 117 | + - removed `LineSliceFields` #590 |
| 118 | + - `png` plugin write speedup ~2.3x by increasing file size about 12% #698 |

| 122 | + - lawrencium (LBL) #612 |
| 123 | + - titan (ORNL) #618 |
| 124 | + - hypnos (HZDR) #670 |
| 125 | + - an `Empty` example was added, which defaults to the setup given by |
| 126 | + all `.param` files in default mode (a standard PIC cycle without lasers nor |
| 127 | + particles), see `src/picongpu/include/simulation_defines/` #634 |
| 128 | + - some source files had wrong file permissions #668 |
| 129 | + |
