Building Tensorflow from source on Ubuntu 16.04LTS for maximum performance:

TensorFlow is now distributed under an Apache v2 open source license on GitHub.

On Ubuntu 16.04LTS+:

Step 1. Install NVIDIA CUDA:

To use TensorFlow with NVIDIA GPUs, the first step is to install the CUDA Toolkit as shown:

Instructions based off of Mistobaan's gist.

These instructions are what I did to install tensorflow on my machine after a segmentation error occured while trying to import tensorflow in python took me 2 days to fix.

Prerequisites

Update brew and install latest packages.

brew update
brew install coreutils swig bazel

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Installing SSHPASS

SSHPass is a tiny utility, which allows you to provide the ssh password without using the prompt. This will very helpful for scripting. SSHPass is not good to use in multi-user environment. If you use SSHPass on your development machine, it don't do anything evil.

Installing on Ubuntu

apt-get install sshpass

	package main

	import (
	"fmt"
	"io/ioutil"
	"log"
	"os"
	"path/filepath"
	)

	#!/bin/bash

	USER=${1:-sebble}

	STARS=$(curl -sI https://api.github.com/users/$USER/starred?per_page=1\|egrep '^Link'\|egrep -o 'page=[0-9]+'\|tail -1\|cut -c6-)
	PAGES=$((658/100+1))

	echo You have $STARS starred repositories.
	echo

	#!/usr/bin/env python

	from influxdb import InfluxDBClusterClient

	influx_host = "127.0.0.1"
	influx_port = 8086
	influx_user = "user"
	influx_pass = "pass"
	database = "example"

	# Ignore all
	*

	# Unignore all with extensions
	!.

	# Unignore all dirs
	!*/

	### Above combination will ignore all files without extension ###

	func readLine(path string) {
	inFile, _ := os.Open(path)
	defer inFile.Close()
	scanner := bufio.NewScanner(inFile)
	scanner.Split(bufio.ScanLines)

	for scanner.Scan() {
	fmt.Println(scanner.Text())
	}
	}
