Running Ubuntu 16.04 LTS I have found this miner to be great
Also works well on Mac OSX and RaspberryPi3 (Raspbian Jessie)

https://github.com/effectsToCause/veriumMiner

Simple steps to run it headless on a Linux server

cd ~/
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev
git clone https://github.com/effectsToCause/veriumMiner
cd veriumMiner
./autogen.sh
./configure CFLAGS="-march=native" --with-crypto --with-curl
make
./cpuminer -o stratum+tcp://poolinat0r.com:4443 -u USERNAME.WORKER -p PASSWORD -t NUMBER_OF_PROCESSORS_TO_USE -B

*NB - You should first make an account at http://vrm.poolinat0r.com/ and also create a worker


The last line you should substitute USERNAME / WORKER / PASSWORD and NUMBER_OF_PROCESSORS_TO_USE
The -B flag sets the miner to run in the background, so you can quit your session and it will still be running

To kill it if needed
sudo killall -9 cpuminer

To compile on MAC OSX simply run the following directly after running the ./autogen.sh command:
./nomacro.pl

Even have the above running on a RaspberryPi 3

Need to change the configure line to the following for Raspbian Jessie on RPi3
./configure CFLAGS="-mcpu=cortex-a53 -mfpu=neon-vfpv4" --with-crypto --with-curl  

Also, for RaspberryPi 3 max number of processors you can use without error is 2
