| bb61289 | Helge Dinkelbach | 21 January 2022, 08:29:53 UTC | directly converting iterator to index should be done using std::distance (I think). | 21 January 2022, 08:29:53 UTC |
| eb3d4c3 | Helge Dinkelbach | 20 January 2022, 10:17:11 UTC | Refactor: provide thread ID as function argument instead of calling omp_get_thread_num() in every step. | 20 January 2022, 10:17:11 UTC |
| 16ab4d6 | Julien Vitay | 19 January 2022, 09:07:18 UTC | Release 4.7.0.2. | 19 January 2022, 09:07:18 UTC |

The different SpMV formats differ in two ways: first the number of arguments/participating variables and the algorithms to compute with. To ease the implementation in the future, the variables required for the connectivity representation and the indices now both located in the corresponding template file (instead of locating them in _configure_template_ids() for instance). | 16 December 2021, 15:28:50 UTC |
| bf64e4f | Julien Vitay | 15 December 2021, 16:16:18 UTC | Script does not need to be executable. | 15 December 2021, 16:16:18 UTC |

| 87a3a7d | Helge Dinkelbach | 10 December 2021, 16:58:29 UTC | continued work on commit f9de07e Changed dense matrices to column_major for spiking models. Otherwise, the the event-driven transmission will perform not efficient. An open question (as for CSRC) remains wether a post_to_pre or pre_to_post order should be favored. | 10 December 2021, 16:58:29 UTC |
| ccffe3f | Helge Dinkelbach | 10 December 2021, 08:17:46 UTC | Merge branch 'master' into develop resolved conflict: version strings | 10 December 2021, 08:17:46 UTC |
| faa1653 | Helge Dinkelbach | 09 December 2021, 13:49:29 UTC | Bugfix/Enhancement (commit 281e272): constants (in this case the uniform delays) are stored as 0-dimensional ndarrays. To detect them, ndim check should be favoured instead of size. | 09 December 2021, 13:49:29 UTC |
| 6f75ad5 | Helge Dinkelbach | 09 December 2021, 11:10:06 UTC | continued work on commit f9de07e Dense matrices and synaptic plasticity (rate-coded) should be fully functional now. | 09 December 2021, 11:10:06 UTC |

| 488f97c | Helge Dinkelbach | 09 December 2021, 11:01:30 UTC | Enhancement (commit a65cd0f, f3e4d9c): disable the introduced mechanism for debug purposes. The introduced mechanism disturbs the usage of gdb/cuda-gdb as the ANNarchyCoreXX.so library is always deleted/moved. Therefore I decided to disable this mechanism if ANNarchy is in debug mode (either by --debug on command line or by compile() argument). | 09 December 2021, 11:01:30 UTC |
| 7ebdb9e | Helge Dinkelbach | 09 December 2021, 10:50:05 UTC | Modified FNP/FP pattern to sort the pre-synaptic ranks in ascending order after RNG. | 09 December 2021, 10:50:05 UTC |

| 462bdb2 | Helge Dinkelbach | 18 November 2021, 08:44:52 UTC | Tried to optimize the performance of the dense matrix implementation on GPUs. Instead of 1-dimensional indexing and only global memory, we use a 2d kernel and a fixed size shared memory. | 18 November 2021, 08:44:52 UTC |

| 0fbd8bf | Helge Dinkelbach | 02 November 2021, 12:59:42 UTC | Commit 77f3a3f10 didn't considered openMP. | 02 November 2021, 12:59:42 UTC |
| 2b4c2b5 | Helge Dinkelbach | 01 November 2021, 16:42:14 UTC | Tentative: "blocked sparse row" (BSR) format for GPUs. This implementation is for now intended solely as rate-coded benchmark (e. g. learning is not working). | 01 November 2021, 16:42:14 UTC |
| 615ce4d | Helge Dinkelbach | 25 October 2021, 08:59:04 UTC | Tentative: moved index definitions (old position from Projection.[..]Generator._configure_template_ids() ) to the specific template files. | 25 October 2021, 08:59:04 UTC |
| d4f6970 | Helge Dinkelbach | 22 October 2021, 07:05:54 UTC | Corrected size_in_bytes (cuda, host side) computation for coo, csr, ell, hyb. | 22 October 2021, 07:05:54 UTC |
| 145fc8d | Helge Dinkelbach | 21 October 2021, 08:58:16 UTC | Restructured CUDA code. Moved all device specific functions to ANNarchyDevice.cu. Added new field to template files which can be used to define common functions for this specific template. | 21 October 2021, 09:01:15 UTC |
| 7be3f79 | Helge Dinkelbach | 21 October 2021, 08:04:41 UTC | Merge branch 'master' into develop | 21 October 2021, 08:04:41 UTC |

| bb35b3c | Helge Dinkelbach | 21 October 2021, 07:37:11 UTC | Improved performance of Coordinate / in particular Hybrid format on GPUs. The current implementation uses atomicAdd to update the target array. To improve the performance of that we want to use shared memory. This requires a guarantee that the threads of one block will not access array elements outside the block. To ensure this, we group the rows in fixed segments. This is done by a helper array built on top and will not effect the ordering of the coordinate format itself. | 21 October 2021, 07:37:11 UTC |
| 77f3a3f | Helge Dinkelbach | 19 October 2021, 08:32:00 UTC | Added memory checks for some sparse matrix formats (GPU as well as CPU). If this checks fail, the init_from_lil method returns false and Projection.initialized will be false. TODO: the CPP-side connectors (currently disabled) need to be adapted. | 19 October 2021, 08:32:00 UTC |
| ff30d7a | Helge Dinkelbach | 14 October 2021, 10:20:33 UTC | Added ELLPACK format on GPUs (required as part of the hybrid ELL/COO format). Code generation fixes for hybrid format (missing ST template parameter). | 14 October 2021, 10:37:08 UTC |
| e68c82b | Helge Dinkelbach | 12 October 2021, 17:03:55 UTC | Added missing deletion of GPU variables in ProjStruct::clear(). Added SIMD implementation for CSR and non-constant weights. Bugfix on dense implementation (spmv code and dendrite_size()). Added CPP side implementation for fixed_probability pattern on dense formats. | 12 October 2021, 17:03:55 UTC |
| 06e6697 | Helge Dinkelbach | 11 October 2021, 16:26:17 UTC | Merge branch 'develop' of https://github.com/ANNarchy/ANNarchy into develop | 11 October 2021, 16:26:17 UTC |
| 4ef956c | Helge Dinkelbach | 11 October 2021, 16:22:42 UTC | Added additional debug messages and sanity checks (e. g. check available memory before allocations on GPUs). Added CPP-side implementation of fixed_number_pre and fixed_probability pattern for ELLPACK-R. | 11 October 2021, 16:22:42 UTC |
| ddc4580 | Julien Vitay | 11 October 2021, 14:34:06 UTC | Updated travis. | 11 October 2021, 14:34:06 UTC |
