# Noteworthy CPU Features
SSE 128-bit vector instructions (e.g. addps http://www.felixcloutier.com/x86/ADDPS.html)
SSE4.1 Makes SSE good
SSE4.2 Makes SSE do strings and CRC32
AVX Makes SSE 256-bit (e.g. vaddps)
AVX2 Adds features to AVX
AVX-512 Makes SSE 512-bit
SHA Makes SSE do SHA1 and SHA256
FMA Fused multiply–add
CLMUL Carry-less multiplication https://goo.gl/ritKJX

#
## SIP Message Parser Definition
#
# The parser should be a linearly complex FSM. It should be able to parse a
# real-world SIP INVITE in less than 30μs. This parser only trades speed in
# favor of friendly data structures, which are big structs linked together.
#
## Implementation Notes

# TensorFlow Nightly Python 2.7 Slow CPU Package Builder on Ubuntu 14
#
# This script is a temporary hackish workaround until the TensorFlow team can
# setup a heterogeneous tooling environment that builds Python<=3.4 CPU pip
# packages using Ubuntu 14, due to challenging constraints imposed by vendors.
#
# It uploads poor quality builds of TensorFlow to GCS for testing environments:
#
# pip install --no-cache-dir -I https://tensorboard-builds.storage.googleapis.com/tf_nightly_cpu_slow_ubuntu14-123-cp27-cp27mu-linux_x86_64.whl
