Subject: [PATCH] Aarch64: Make memcpy more compatible with device memory

For normal non-cacheable memory ACE supports 4x128 bit r/w WRAP
transfers or 1x128 bit r/w INCR transfers.  By re-ordering the
stp's in memcpy / memmove we can accomodate this better without
impacting the existing code.

Sometimes you need to use API Keys to use things like the Speech API. And then you Google a bit and follow all the instructions. But the Chromium Project's API Keys page does a not-so-great of explaining how to do this, so I will.

1. Download Chromium.
2. You'll notice a yellow disclaimer message appear as a doorhanger: Google API Keys are missing. Some functionality of Chromium will be disabled. Learn More.
3. Clicking on that link takes you to the confusing API Keys docs page.
4. If you aren't already, subscribe to the [email protected] mailing list. (You can just subscribe to the list and choose to not receive any mail. FYI: the Chromium project restricts the APIs to those subscribed to that group - that is, Chromium devs.)
5. Make sur

Installing the NVIDIA driver, CUDA and cuDNN on Linux (Ubuntu 20.04)

This is a companion piece to my instructions on building TensorFlow from source. In particular, the aim is to install the following pieces of software

• NVIDIA graphics card driver (v450.57)
• CUDA (v11.0.2)
• cuDNN (v8.0.2.39)

on an Ubuntu Linux system, in particular Ubuntu 20.04.

High-Performance Matrix Multiplication

This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).

Intro

Matrix multiplication is a mathematical operation that defines the product of

I have spent quite a bit of time figuring out automounts of NFS shares in OS X...

Somewhere along the line, Apple decided allowing mounts directly into /Volumes should not be possible:

/etc/auto_master (see last line):

# Automounter master map
