I have worked a fair amount with parallelism of code. But not familar
with 'TBB' - anyone care to clarify?
I have recently come to know of NuPIC and just recently downloaded but
have yet to look, build nor install. It will be a week or so till my
schedule opens up enough.
I'm all for speed and speed means minimal layers of code, working more
directly with the HW, such at the GPU using the libraries directly.
But, I don't know the efficacy of OpenCV (another thing for me to look
into).

Well, i will keep you updated regarding any response from OpenCV. I
believe that they use TBB but unsure what role that plays in thread
safety as opposed to creating threads.

I would think so, especially since it would allow more people to
contribute.

Would OpenCL be a better direction than pure GPU?
I've asked on the OpenCV forum how they have approached this.
There are a number of options.

I would love to discuss how we would go about making NuPIC
parallel. We could really use the boost in bandwidth,
especially as we approach the future. If we could easily
refactor the C++ implementation to use the graphics card,
that could enable applying the CLA to problems that require
low latency computation.

HI Chetan,
I can certainly do that in the next couple of months. If
we could find an answer to this, then i can make some
progress towards this in a massively parallel and async
way. ;)
As far as i am aware, OpenCV is completely thread safe.
Maybe we could take some inspiration from there.
Regards,
Daniel

Daniel,
Great question! I'm not entirely sure, but I just
wanted to say that it would be great if someone
experimented with parallelizing NuPIC :)

Hello,
I am interested in the progress of this project.
From the activity on the mailing lists, i can see
that the next few months will be very interesting as
more material becomes available. I am yet to
download and install due to time restrictions on my
current workload.
My intention is to use this project within my
application once it is in a more stable state. When
designing my application i am attempting to use a
large amount multi-threading and so i want to know
what considerations i will need to think about.
How thread safe are the C++ bindings? What aspects
would require locking for async tasks.
My application will lean toward detection and
classification problems for 2D matrices.
Regards,
Daniel
