NVIDIA Volta has just been made available to wide public through AWS. We have tested DigiCortex v1.22 on a 8x NVIDIA V100 system and achieved real-time simulation performance of 12.6 million neurons and 431 million synapses, which is almost 3x speedup compared to K80!

We have tested DigiCortex v1.22 on a dual NVIDIA P100 accelerator with significant results: real-time simulations of 5 million neurons and 200 million synapses are possible, thanks to the HBM2 memory bandwidth and other Tesla P100 features. Click on the article to read more.

DigiCortex v1.21 brings improvements in the GPU area: it now includes support for multi-GPU CUDA-accelerated simulations and a full support for the latest generation NVIDIA Pascal GPU architecture

DigiCortex 1.16 fixes a nasty bug which resulted in crashes when running on systems with more than 64 logical cores. This happened on our test system based on dual-CPU setup with Intel Xeon E5 2699 V3, which is the first time a 2S system has >64 logical cores. Fix is available with DigiCortex 1.16, and the article shows SpikeFun 1.16 managing to take 100% of all 72 logical Haswell EP cores.

NVIDIA GeForce GTX TITAN X comes with 12 GB of video memory, making it ideal GPU for neural network simulations, including spiking neural networks.Upcoming version of DigiCortex engine (v1.14) can simulate more than million multi-compartment neurons on a single TITAN X GPU!

SpikeFun 1.10 release comes with performance monitoring code update adding support for Intel Haswell EP/EX (Xeon E5/E7 v3) CPUs as well as Intel Crystalwell CPUs.

SpikeFun 1.05 release comes with the first version of DigiCortex SDK. With DigiCortex SDK it is now possible to connect to the running simulation and obtain information about neuron states, inject current into any compartment and get spiking information. Click on the title to read more...

DigiCortex Engine can be used to model some of the emergent phenomena of the developing cortex. In this article we show how spontaneous orientation sensitivity of the primary visual cortex (V1) cells develops in presence of natural video signal and voltage-dependent spike-timing dependent plasticity (vSTDP).

Since Intel Xeon E5 2600 v2 has been out publically, it is time to show some results of DigiCortex engine on the new dual 12-core setup (24 cores / 48 threads total) based on Intel Xeon 2697 v2 CPU. Result: we clock nearly perfect 1.45x speed-up! Click on the article to read more!
