Obfuscate nxsdk information #228

merged 5 commits into from Jun 21, 2019


Copy link

commented Jun 10, 2019

Intel has requested that we obfuscate information related to the nxsdk API (since it is not publicly available). This is an attempt at doing so.

Note that the goal here is not to make the obfuscated information unrecoverable, but simply to obscure it from a surface viewing.

There are three major things I was considering in the obfuscation:

  1. Hiding any direct calls to nxsdk objects
  2. Renaming any nengo-loihi classes/functions/variables that directly correspond to equivalent nxsdk objects
  3. Hiding any constant values (e.g. register sizes) that are based on information inside nxsdk
nengo_loihi/ Outdated Show resolved Hide resolved
nengo_loihi/ Outdated Show resolved Hide resolved

Rename many attributes
This decouples Nengo Loihi from NxSDK in preparation for
obfuscating the NxCore API.
Pin TensorFlow<1.14 for tests
The test failure seems to be a very small floating point
difference that doesn't happen in earlier TensorFlow versions,
so we downgrade for now and will look into the differences
in more detail later.
Add debug statements for failed copies
This seems to be the underlying issue when two processes attempt
to build Loihi models at the same time. Reproducing the error and
fully debugging it is time consuming, so we're adding these print
statements in for now so that if the tests randomly fail again we
can get some more insight for further debugging.
