Bluehive and OSB interactions
-----------------------------

Discussion of the options for running models from OSB (and any other models expressed in LEMS/NeuroML2) on the Bluehive hardware being developed in Cambridge.

Some of these points may be applicable to other FPGA based simulator systems.

### Overview of Bluehive system

Information on the current status of the Bluehive system can be found in presentations by Steve Marsh ([PDF](http://www.opensourcebrain.org/attachments/download/70/SteveMarsh_HiveMind_Overview_13_5_13.pdf)) [Steve Marsh](http://www.opensourcebrain.org/attachments/download/70/SteveMarsh_HiveMind_Overview_13_5_13.pdf) and Paul Fox ([PPT](http://www.opensourcebrain.org/attachments/download/74/Thousands-to-millions_PaulFox.ppt)) [Paul Fox](http://www.opensourcebrain.org/attachments/download/74/Thousands-to-millions_PaulFox.ppt) at the [2013 OSB kickoff meeting](http://www.opensourcebrain.org/projects/osb/wiki/Meetings)

### Potential OSB models to test on Bluehive hardware

Some of the potential models on OSB which could be tried out on Bluehive include:

- project:brunel2000
- project:destexhe\_jcns\_2009
(Note these are both PyNN based networks, which could potentiall be scaled up by changing the population size parameters)
- project:grancelllayer
(This is a neuroConstruct based project containing a network of single compartment conductance based neurons. The [Large 3D network](http://www.opensourcebrain.org/embedded/grancelllayer/Large3DNetwork.html) simulation configuration could be used for testing on Bluehive, but would require more testing of the ChannelML ~~\> NeuroML2~~\> LEMS -\> Other formats pathway)

Note that a Google Summer of Code project for the INCF will start soon when a student will be specifically looking at converting large scale cortical models to NeuroML/PyNN and putting them on OSB: http://www.incf.org/gsoc/2013, http://www.google-melange.com/gsoc/project/google/gsoc2013/vitorchaud/14001.

These networks will be exactly the type needed for testing with Bluehive and comparing to other simulators.

### Initial model for testing by Mike Hull

Mike Hull will initially investigate translating his swimming tadpole model to run on this system: [https://github.com/mikehulluk/Cambridge2013](https://github.com/mikehulluk/Cambridge2013)

### Libraries which can be used for code generation, testing, etc.

[PyLEMS](https://github.com/LEMS/pylems)
Extended [org.neuroml.export package](https://github.com/NeuroML/org.neuroml.export/tree/master/src/main/java/org/neuroml/export) which exports [VFGEN](http://www.warrenweckesser.net/vfgen/index.html) format, to generate C/C++…

### Meetings

A meeting will take place in Cambridge on Monday 22nd July to discuss this work and future directions.

### Other simulator systems based on FPGA

Please add comments if you know anything about the state of these systems (but be nice, it’s public!).
