Dolazeci v1.21 ce podrzavati multi GPU kao i optimizacije za NVIDIA Pascal arhitekturu...

Evo malog preview-a performansi:

http://www.digicortex.net/node/51

1.8 miliona neurona sa 70 miliona sinapsi u realnom vremenu, na jednom GP102 GPU-u. Poboljsanja u odnosu na Maxwell generaciju su do 2.08x, a to je sve sa GDDR5X memorijom.

50% brza HBM2 memorija bi sigurno ovaj rezultat poboljsala jos solidno.

O Multi GPU podrsci vise informacija uskoro :)

Performance seems still better ;-)
Ivan, do you think - will be there sometime in future support for another sensory inputs (acoustic, thermo, attitude, etc ) besides retinal input?
And new and old question - will you release source code ever?

@lospalos,

Thanks! Yes, I plan to add support for additional sensory inputs, it is on my TODO list :)

As for the source code, no plans as of right now. I would suggest to check Brian simulator in case you are looking for source code of AdEx / Izhikevich neuron models or voltage-based STDP implementations.

v1.22 is out:

http://www.digicortex.net/node/7

Citat:

------------------------------------------------------------------------
v1.22 - Released on May 2nd 2017
------------------------------------------------------------------------

* CUDA simulations will limit GPU firings buffer size in case there is
not enough VRAM for default firings buffer size. When operating with
constrained firings buffer size, some spikes might be missed

* Fixed the problem preventing simulations from starting on systems
with 16 GPUs due to memory allocation failure


------------------------------------------------------------------------
v1.21 - Released on April 25th 2017
------------------------------------------------------------------------

* Added support for NVIDIA Pascal architecture

* Support for simultaneous use of multiple NVIDIA CUDA devices, please
see comments in DigiCortexConfig.cuda

* Fixed CPU discovery on systems with number of CPU groups higher
than four

* CUDA compute now requires at least Kepler generation GPU

* Added configuration option for forcing circuit builder to generate
neurons with single compartments (<ForceSingleCompartmentNeurons>),
for usage please see Demo*_SingleCompartment.xml files

* Added more example projects (_SingleCompartment.xml)



Sada DigiCortex moze da radi sa 16 GPU-ova.

Screenshot simulacije 16.7 miliona neurona sa 579 miliona sinapsi na 16 NVIDIA K80 GPU-ova - 0.26x real-time.

Possibly much more interesting would be to see some examples detailing the methods for reconstructing the neural connectivity and doing axonal guidance from the DTI data. Could you write a post or article about that at some point or point to relevant literature?

Zanimljivo, mislim da je Blue Brain Project dobio solidno superracunarsko vreme za dalje istrazivanje u ovom pravcu, videcemo krajem godine kakve ce to rezultate dati.

Konacno rezultati na NVIDIA P100 ("Big Pascal") sistemu:

http://www.digicortex.net/node/53

P100 je stvarno zver od kartice, sa 2 komada DigiCortex moze da simulira 5 miliona neurona / 200 miliona sinapsi u realnom vremenu. Takodje, ubrzanje u odnosu na "consumer" Pascal GPU (GP102 / 1080 Ti) je prilicno. Razlog za to je mnogo veci dostupni memorijski protok (720 GB/s vs. 484 GB/s) kao i mogucnosti koje samo Tesla kartice imaju (preklapanje memorijskih transfera).

Evo kako izgleda poredjenje performansi izmedju GP100, GP102 i GM200 na jednom GPU-u:



I, tabela performansi na referentnim sistemima:

v1.22 na 8x NVIDIA Volta V100

16 miliona neurona, 575 miliona sinapsi - 0.75x real-time. Zauzece Voltinog memorijskog kontrolera: 95% (to je 855 GB/s, po kartici), nije lose :-)

To je skoro 3x bolje od K80...
