Revision Author Date Message Commit Date
f438f03 Julien Vitay 14 December 2022, 10:47:50 UTC Runge-Kutta 4 (rk4) is now available. 14 December 2022, 10:47:50 UTC
226063b Julien Vitay 14 December 2022, 10:27:19 UTC Merge branch 'develop' 14 December 2022, 10:29:22 UTC
089d93a Julien Vitay 14 December 2022, 10:25:55 UTC Call to warning() was not imported. 14 December 2022, 10:25:55 UTC
8474439 Helge Dinkelbach 14 December 2022, 10:11:47 UTC updated changelog. 14 December 2022, 10:11:47 UTC
b27ef35 Helge Dinkelbach 14 December 2022, 09:52:20 UTC Added a flag to explicitly disbale the mechanism introduced in a65cd0f (already did for debug in 488f97c). 14 December 2022, 09:52:20 UTC
a8f78d1 Helge Dinkelbach 14 December 2022, 08:35:48 UTC Bugfix in Convolution: the filters could not be changed after compile(). 14 December 2022, 08:39:38 UTC
c2393d9 Helge Dinkelbach 14 December 2022, 08:21:30 UTC In commit 77f3a3f we changed the implementation of the 'initialized' flag from only indicating the call of _connect to store if the c++ connectivity methods were correctly called. SpecificProjections override the _connect() method and consequently the 'initilized' flag was not initialized (i.e. None). 14 December 2022, 08:29:31 UTC
cd574fa Helge Dinkelbach 13 December 2022, 16:20:45 UTC Bugfix in code generation related to post-event and CSR on GPUs. 13 December 2022, 16:20:45 UTC
04c73ac Helge Dinkelbach 13 December 2022, 11:20:53 UTC removed unnecessary import introduced in commit e6bcde9. 13 December 2022, 11:20:53 UTC
e0b4daa Helge Dinkelbach 13 December 2022, 09:53:55 UTC Bugfix in code generation related to splitted CSRC/CSRC_T. 13 December 2022, 09:53:55 UTC
ed60b24 Helge Dinkelbach 13 December 2022, 09:40:11 UTC removed debug print 13 December 2022, 09:40:11 UTC
6613b97 Helge Dinkelbach 13 December 2022, 09:12:44 UTC Added sanity rule to prevent usage of CSRC_T and GPUs for non-default synapses. Improved readability of code (commit b66fdf5). 13 December 2022, 09:12:44 UTC
e3f2d82 Helge Dinkelbach 13 December 2022, 08:44:08 UTC Updated sanity rules to prevent the usage of continuous transmission on spiking synapses with pre-to-post matrix ordering. The continuous transmission kernel is derived from the rate-coded psp. Therefore, the inversed matrix view of the CSRC_T would introduce many misaligned memory accesses. In case of openMP one would also probably need atomic operations. 13 December 2022, 08:44:08 UTC
b66fdf5 Helge Dinkelbach 13 December 2022, 08:15:46 UTC Sanity rules for sparse matrix formats and rate-coded models should consider the hardware. 13 December 2022, 08:15:46 UTC
e16b13b Helge Dinkelbach 12 December 2022, 16:18:12 UTC Tentative: added implementation for spiking models using uniform delays and CSR on GPUs. 12 December 2022, 16:18:12 UTC
45588a6 Helge Dinkelbach 12 December 2022, 15:37:55 UTC minor change on unittest. 12 December 2022, 15:37:55 UTC
c5588c7 Helge Dinkelbach 12 December 2022, 15:36:27 UTC nonuniform delays are not supported yet on GPUs. 12 December 2022, 15:36:27 UTC
7bc8feb Helge Dinkelbach 12 December 2022, 11:19:40 UTC Bugfix in single item update using CSR. 12 December 2022, 11:19:40 UTC
8e507a1 Helge Dinkelbach 12 December 2022, 11:12:44 UTC ELLPACK-R: fixed single item update for CPU/GPU. 12 December 2022, 11:12:44 UTC
5d096dd Helge Dinkelbach 12 December 2022, 11:07:08 UTC Removed debug print left from commit 35b0de4. 12 December 2022, 11:07:08 UTC
82de4de Helge Dinkelbach 12 December 2022, 09:05:58 UTC Single item getter for dense matrix format was missing. 12 December 2022, 09:05:58 UTC
d3792c9 Helge Dinkelbach 12 December 2022, 08:49:55 UTC Implemented get/set for single matrix values for BSR (CPU/GPU) 12 December 2022, 08:49:55 UTC
d788821 Helge Dinkelbach 11 December 2022, 17:31:10 UTC Bugfix (commit 5b24fb5): the change performed in this commit did not adjust the code templates for min/max/mean. 11 December 2022, 17:31:59 UTC
064f68d Helge Dinkelbach 11 December 2022, 12:38:23 UTC Fixed code generation bugs related to non-uniform delays. 11 December 2022, 12:38:23 UTC
41d842d Helge Dinkelbach 11 December 2022, 11:24:45 UTC Addendum (commit 518b3a1): the custom connectivity classes did not considered the storage_format argument. 11 December 2022, 11:24:45 UTC
7f85445 Helge Dinkelbach 11 December 2022, 10:04:27 UTC Temporarily disabled pooling on GPU devices as the code templates are currently broken. The feature is anyways not useable right now, as the convolution is still missing on GPUs. 11 December 2022, 10:04:27 UTC
7396014 Helge Dinkelbach 10 December 2022, 15:55:11 UTC missing include statement for SpecificProjections on GPUs. 10 December 2022, 15:55:11 UTC
518b3a1 Helge Dinkelbach 10 December 2022, 15:52:47 UTC restructured unittests for custom connectivity and rate-coded psp. - no delay, uniform delay and non-uniform delay are now three classes - non-uniform delays are not supported on GPUs and therefore not tested 10 December 2022, 15:52:47 UTC
456351f Helge Dinkelbach 08 December 2022, 15:16:41 UTC Merge branch 'master' into develop 08 December 2022, 15:16:41 UTC
2a58a18 Helge Dinkelbach 08 December 2022, 10:36:16 UTC using consistant types. 08 December 2022, 10:36:16 UTC
8bc9663 Julien Vitay 05 December 2022, 16:25:45 UTC Bug with midpoint. 05 December 2022, 16:25:45 UTC
8df6eb7 Julien Vitay 05 December 2022, 16:14:04 UTC The parser made replacement errors when targets had overlapping names (e.g. sum(exc2) and sum(exc) used in that order). 05 December 2022, 16:14:04 UTC
73c3174 Julien Vitay 25 November 2022, 15:56:42 UTC Version 4.7.1.6 25 November 2022, 15:56:42 UTC
439de48 Helge Dinkelbach 23 November 2022, 16:00:10 UTC updated changelog. 23 November 2022, 16:00:10 UTC
320af51 Helge Dinkelbach 23 November 2022, 15:48:43 UTC updated changelog. 23 November 2022, 15:48:43 UTC
ba6497d Helge Dinkelbach 23 November 2022, 15:44:23 UTC Bugfix: period_offset argument was ignored when creating object copy. 23 November 2022, 15:44:23 UTC
ff8b4f0 Helge Dinkelbach 21 November 2022, 08:58:16 UTC Tentative: modified test for save_and_load of projection parameters. The original tests fail, because the save function access the init attribute to gain the stored value. But the init value is only updated by access before compile(). The modifications which should be tested are performed after compile which let the test fail. Therefore I added another field in the test to store the initial states before compile(). 21 November 2022, 08:58:16 UTC
42fd859 Helge Dinkelbach 11 November 2022, 12:23:00 UTC Addendum (f2190e0): GPUs does not support CSRC_T, Dense_T for spiking models which are selected by automatic format selection on CPUs. Therefore, we fall back to CSRC on GPUs. 11 November 2022, 12:23:00 UTC
c5b7ac1 Helge Dinkelbach 10 November 2022, 18:40:03 UTC Continued work on fcba8bd. - the offsets need to be considered by get/set methods. 10 November 2022, 18:40:03 UTC
625954d Helge Dinkelbach 10 November 2022, 17:20:41 UTC Bugfix: related to Dense matrix representation and PopulationViews. If the matrix contains empty rows, the post_ranks need to be considered when constructing the mask which was not done. 10 November 2022, 17:20:41 UTC
aaa6223 Helge Dinkelbach 09 November 2022, 19:47:00 UTC Refactor (commit fcba8bd), same as commit d855701 but for openMP. Further, disabled the optimization for now until the feature is fully tested. 09 November 2022, 19:47:00 UTC
f92f460 Helge Dinkelbach 09 November 2022, 19:30:04 UTC Addendum (0491ef1): dense matrices. 09 November 2022, 19:30:04 UTC
d855701 Helge Dinkelbach 09 November 2022, 19:24:52 UTC Refactor (fcba8bd): instead of splitting the dictionary fields, I added a separate template file for this specialized implementation. 09 November 2022, 19:24:52 UTC
4052f6a Helge Dinkelbach 09 November 2022, 07:42:00 UTC updated changelog. 09 November 2022, 07:42:00 UTC
528eabb Helge Dinkelbach 09 November 2022, 07:22:35 UTC Bugfix (988b5e5): the psp argument provided to PoolingProjection() was not copied. 09 November 2022, 07:30:27 UTC
f1064f6 Helge Dinkelbach 09 November 2022, 07:16:27 UTC Suppressed xrange(). The usage of xrange is a Python2.x related optimization. In Python3.x the xrange() implementation was used to implement range(). 09 November 2022, 07:16:27 UTC
7e03c58 Helge Dinkelbach 09 November 2022, 06:52:49 UTC Changed ctype for boolean values on GPUs to char. For local/semiglobal variables we create a vector<ctype> instance. In the modern STL container implementation std::vector<bool> is a specialized container which (compiler dependent) may specialized as bitset container (see: https://en.cppreference.com/w/cpp/container/vector_bool). However, for GPUs this is not suitable and therefore transformation of the boolean value on GPUs into a char datatype. 09 November 2022, 06:57:21 UTC
f2190e0 Helge Dinkelbach 08 November 2022, 07:18:55 UTC Extended heuristic format selection. Spiking networks with high density should switch to Dense, pre-to-post representation. 08 November 2022, 07:18:55 UTC
099a162 Helge Dinkelbach 08 November 2022, 07:11:27 UTC ConnectorMethods functions should use None as default argument storage_format/storage_order. Using None we can clearly separate between explicit choices made by users and default arguments. 08 November 2022, 07:11:27 UTC
078ff35 Helge Dinkelbach 08 November 2022, 06:51:25 UTC updated changelog. 08 November 2022, 06:51:25 UTC
fe5b937 Helge Dinkelbach 08 November 2022, 06:47:40 UTC PopulationView expects a numpy.array since commit (5f9d58b). 08 November 2022, 06:47:40 UTC
35b0de4 Helge Dinkelbach 08 November 2022, 06:46:41 UTC Tentative: added new debug symbol (_DEBUG_ACCESSOR) to trace accessor function calls (test-wise implemented for LIL) 08 November 2022, 06:46:41 UTC
1bd613a Helge Dinkelbach 08 November 2022, 06:06:23 UTC Merge branch 'master' into develop 08 November 2022, 06:06:23 UTC
050ac35 Helge Dinkelbach 08 November 2022, 05:56:47 UTC Addendum (a7123ed): suppressed the idx value of IndividualSynapse as it is not needed anymore. 08 November 2022, 05:57:54 UTC
a7123ed Helge Dinkelbach 08 November 2022, 05:48:36 UTC Bugfix related to the used index in IndividualSynapse When using calls like projection[post_rank][pre_rank] this leads to the creation of IndividualSynapse() objects. This object used the lil-idx (i.e. the position of pre_rank in the pre_ranks array) which was fine for earlier versions of ANNarchy which only used lil. For csrc, ellpack etc. I changed this accessors to expect the pre_rank not the index position. 08 November 2022, 05:48:36 UTC
e295a75 Helge Dinkelbach 03 November 2022, 11:01:14 UTC Merge branch 'master' into develop Notice: The conflict was on the configure_template_ids update tree. In earlier versions, we stored there the indices. Later I stored them together with the other template code. 03 November 2022, 11:01:14 UTC
407aae1 Helge Dinkelbach 03 November 2022, 10:50:14 UTC Bugfix in code generation: for sliced LIL, spiking and uniform delays the tid was forgotten when accessing the delay container. 03 November 2022, 10:50:14 UTC
0491ef1 Helge Dinkelbach 02 November 2022, 07:36:24 UTC Added inner-/outer-loop distinction for event-driven transmission. Our preliminary results and literature suggest that one need to distinguish between a parallelization on the inner- or outer-loop of the event-driven transmission kernel. For splitted matrices, one will always use outer-loop. 02 November 2022, 07:36:24 UTC
655dc5a Helge Dinkelbach 02 November 2022, 06:51:39 UTC Added partitioned implementation for CSRC + post_to_pre view. 02 November 2022, 06:51:39 UTC
eb2602b Helge Dinkelbach 31 October 2022, 09:03:24 UTC Bugfix (844c816): storage_order argument was missing in connect_from_matrix_market declaration 31 October 2022, 09:03:24 UTC
8d43915 Helge Dinkelbach 27 October 2022, 16:34:30 UTC Applied the changes made in commit fcba8bd also for dense matrix and post_to_pre ordering. 27 October 2022, 16:34:30 UTC
27d5d47 Helge Dinkelbach 27 October 2022, 08:36:57 UTC Merge branch 'master' into develop 27 October 2022, 08:36:57 UTC
d8b09de Helge Dinkelbach 27 October 2022, 08:29:18 UTC Bugfix: a simulate() after a Monitor.stop() call crashed. Monitor.stop() removes the C++ instance and set the corresponding position in the recorders array to nullptr. However, the simulation code need to check if a recorder was disabled in this way otherwise this leads to a segmentation fault. 27 October 2022, 08:29:18 UTC
c8569a6 Helge Dinkelbach 27 October 2022, 06:11:45 UTC CSRC_T and learning appears to work correctly, therefore I remove this sanity check. 27 October 2022, 06:11:45 UTC
85f53dd Helge Dinkelbach 26 October 2022, 16:38:13 UTC Profiling: added measurement of the post_event kernel. 26 October 2022, 16:38:13 UTC
4560eec Helge Dinkelbach 26 October 2022, 15:50:00 UTC Marked the profiling using PAPI-API as deprecated. 26 October 2022, 15:50:00 UTC
630fd77 Helge Dinkelbach 26 October 2022, 15:35:25 UTC The headers contained in thirdparty sub-folder need to be copied during setup. 26 October 2022, 15:35:25 UTC
5e7984f Helge Dinkelbach 25 October 2022, 17:16:37 UTC Extended the parser to compute the number of evaluated operations for equations. 26 October 2022, 15:32:32 UTC
d3f69a7 Helge Dinkelbach 25 October 2022, 07:21:59 UTC Tentative: for spiking neurons as target of convolution/pooling the psp-variable must be adjusted. 25 October 2022, 07:21:59 UTC
4db0fc1 Helge Dinkelbach 25 October 2022, 06:39:19 UTC Tentative: removed rate-coded neuron check for pooling/convolution to allow easier development on the ann_to_snn_conversion extension. 25 October 2022, 06:39:19 UTC
988b5e5 Helge Dinkelbach 25 October 2022, 06:37:21 UTC Pooling: Bugfix (fc64001) and allow to overwrite default psp (already allowed on convolution). 25 October 2022, 06:38:20 UTC
1a135ae Helge Dinkelbach 25 October 2022, 06:33:56 UTC Convolution: Bugfix (fc64001) and added same sanity check as in Pooling. 25 October 2022, 06:35:08 UTC
126575d Helge Dinkelbach 24 October 2022, 14:39:09 UTC Removed doubled CoupledEquations.c_code definition. 24 October 2022, 14:39:09 UTC
04ab383 Helge Dinkelbach 24 October 2022, 14:37:58 UTC Merge branch 'master' into develop 24 October 2022, 14:37:58 UTC
b1d79bc Julien Vitay 23 October 2022, 13:35:58 UTC Extra tab in midpoint. 23 October 2022, 13:35:58 UTC
602cb5c Helge Dinkelbach 20 October 2022, 07:38:31 UTC removed trailing spaces. 20 October 2022, 08:05:23 UTC
d45ce63 Helge Dinkelbach 19 October 2022, 11:33:43 UTC Bugfix (844c816): storage_order argument was missing in connect_with_func declaration. 19 October 2022, 11:33:43 UTC
fc64001 Helge Dinkelbach 18 October 2022, 17:41:12 UTC Extended sparse matrix format selection heuristics to select the storage_order for rate-coded and spiking models too. 18 October 2022, 17:41:12 UTC
5128dcd Helge Dinkelbach 17 October 2022, 12:35:48 UTC Added "annarchy_json" argument to parallel_run(). Normally, the user can adjust the compiler configuration in advance of calling this function. However, there is the option, that the compile is performed during parallel_run() and therefore this flag must be adjustable. 17 October 2022, 12:35:48 UTC
4ab147c Helge Dinkelbach 15 October 2022, 07:51:46 UTC Bugfix (6030556): row_nr_off needs to be computed in each iteration by the threads separatly, not incrementally add up. 15 October 2022, 07:51:46 UTC
2a14971 Helge Dinkelbach 15 October 2022, 07:46:08 UTC BSRMatrix: more fine-grained debug. The print-out of the tiled mask is now performed only if _DEBUG_CONN is enabled. Otherwise the normal _DEBUG is too noisy. 15 October 2022, 07:46:08 UTC
6030556 Helge Dinkelbach 15 October 2022, 06:49:57 UTC Tentative: openMP for block sparse row This commit adds a simple openMP parallelization for the BSR format. The parallelization is applied simply across the block_row. 15 October 2022, 06:49:57 UTC
a20665d Helge Dinkelbach 15 October 2022, 04:32:54 UTC cleaned up sliced ELLPACK template header. Added a hyper-parameter printout (as for BSR). 15 October 2022, 04:32:54 UTC
8ee024e Helge Dinkelbach 15 October 2022, 04:32:14 UTC Fixed sanity check for sliced ELLPACK - single thread. 15 October 2022, 04:32:14 UTC
ecf3f28 Helge Dinkelbach 13 October 2022, 12:46:39 UTC Merge branch 'develop' of https://ai.informatik.tu-chemnitz.de/gogs/annarchy/ANNarchy into develop 13 October 2022, 12:46:39 UTC
d18f9ee Helge Dinkelbach 13 October 2022, 08:38:54 UTC minor code change (TimedArray, CUDA) The NVCC compiler complained about the unnecessary first arguments in the for-loop statement. 13 October 2022, 08:38:54 UTC
5be9857 Helge Dinkelbach 13 October 2022, 08:35:59 UTC In verbose mode ANNarchy notifies the user which files were changed and had forced a recompile. 13 October 2022, 08:35:59 UTC
38963e1 Helge Dinkelbach 05 October 2022, 17:38:21 UTC Implemented two functions related to _DEBUG_CONN flag. 05 October 2022, 17:38:21 UTC
e31b53b Helge Dinkelbach 05 October 2022, 09:46:54 UTC updated changelog. 05 October 2022, 09:46:54 UTC
dc48293 Helge Dinkelbach 05 October 2022, 09:24:50 UTC Allowed thread placement using CPU_SET also for single-thread applications. 05 October 2022, 09:24:50 UTC
0eaf52a Helge Dinkelbach 05 October 2022, 07:02:09 UTC tentative feature: try to implement thread placement rules for parallel_run 05 October 2022, 07:02:09 UTC
df7d4a6 Helge Dinkelbach 01 October 2022, 08:56:03 UTC Updated changelog. 01 October 2022, 08:56:03 UTC
fcba8bd Helge Dinkelbach 30 September 2022, 13:07:54 UTC Added specialized implementation for dense matrices to reduce the memory requirement in context of PopulationViews 30 September 2022, 13:07:54 UTC
a4aab28 Helge Dinkelbach 29 September 2022, 05:47:59 UTC The mask type (default char) of dense matrices is now a template parameter. 29 September 2022, 05:47:59 UTC
f09ad6e Helge Dinkelbach 28 September 2022, 18:37:51 UTC Implemented two missing set methods for dense matrix format. 28 September 2022, 18:37:51 UTC
ec8f4ed Helge Dinkelbach 28 September 2022, 13:39:07 UTC Fixed class names in template header library. 28 September 2022, 13:39:07 UTC
4dd0aaa Helge Dinkelbach 28 September 2022, 13:29:15 UTC Bugfix: wrong index variable for synapse runinning index in the pre_spike event code (CSRC_T matrix). 28 September 2022, 13:29:15 UTC
ff9c934 Helge Dinkelbach 26 September 2022, 16:46:49 UTC QuickFix (commit 5f9d58b): Monitor crashes when accessing Population.ranks In commit 5f9d58b I replaced the Population.ranks generation from Python list to numpy.arange(). The monitors use the ranks and provide them to C++ core. This commit fixes this for now, by converting the ranks locally in the PopulationView object to a Python list. 26 September 2022, 16:46:49 UTC
2893199 Helge Dinkelbach 26 September 2022, 16:42:53 UTC Added new unittest related to record of PopulationViews. Next to slicing (e.g. Population[:,2]), one can unify two different populations. There are two cases: a) PopView + PopView and PopView + IndividualNeuron. The latter was not tested yet. 26 September 2022, 16:42:53 UTC
fa17a70 Helge Dinkelbach 25 September 2022, 06:14:04 UTC This commit relaxes the assert() in BSRMatrix::init_matrix_from_lil(). The previous assert condition on the theoretical number of allocated blocks was a bit strong. Now we check for allocated blocks if a problem arise. Additionally, we check the allocation of dense blocks if we have enough space in RAM. 25 September 2022, 06:14:04 UTC
