The purpose of this post has been to essentially highlight all the changes I had to make in order to successfully run the toy example from the book on a mixture of OS X and Linux machines all running locally. (Again, notice the additional ‘-‘ in the paste commands). Next, you’ll activate Parallels Desktop Business Edition.

This command is also from the book and will give you the sum – you basically just summed 100 numbers each separately on the slave machines through different parallel processes, and then summed the 10 sums locally. Download the Parallels Desktop installer to your Mac. $ seq 1000 | parallel -N100 –pipe –slf instances “paste -sd+ – | bc” | paste -sd+ – | bc Cadmius happens to have 8 CPUs (and 32 cores).įinally, run the following to sum the numbers in parallel and then sum the 10 sums on the host machine: In this case I did install Parallel on the master and two slaves, but it seems Parallel doesn’t like the fact that macusers-Macbook is an older machine with a Core 2 Duo? Not sure about that. I’ve mentioned how Parallel doesn’t need to be installed on all machines for basic usage. The output shows the hostnames and the number of numbers passed over to the slaves. With it, both OS X and Ubuntu seem happy (yet you can see the differences in the outputs from the two kinds of machines).Īpart from that difference, the command is copied from the book it is basically generating a sequence of 1000 numbers, and distributing them to the slaves. The book doesn’t have it because you do not need it on Linux. Notice the additional ‘-‘ after the arguments to paste. The main machine through which I am parallelizing things is also running OS X Mavericks. In my case, Cadmius happens to be Ubuntu 14.04, and macusers-Macbook is running OS X Mavericks. I need to install GNU grep on my Mac but I'm finding some difficulties.I tried doing this:brew install grep -with-default-namesBut this is no longer an option since Homebrew removed -with-d. Next, create your instances file (named ‘instances’), and add the hostnames of your local machines as shown in the screenshot. Here is a walkthrough that basically replicates the toy example in the book, but highlights the differences you’ll need to incorporate in an OS X environment.įirst, you can install GNU Parallel on OS X through Homebrew: (3) you are using the OS X variant of paste (which has a nuance compared to the Ubuntu version)

(2) all your machines are local (as in connected through a LAN)

(1) you are primarily using OS X and might have some Ubuntu machines as some of your instances Download Audacity Download the free Audacity audio editor for Windows, Mac or Linux from our download partner, FossHub: Download Audacity for Windows, Mac or Linux Audacity is free of charge. I am presenting a tutorial that works with the premise that (3) you are using GNU paste that comes pre-installed on all Ubuntu systems (2) you are using a bunch of Amazon EC2 instances to do your parallelization (and hence need to find out the IPs of all your instances in a non-straightforward way) (1) all machines you are using are running Ubuntu or some variant of Linux The toy example/ tutorial in the book makes three assumptions:

The book Data Science at the Command Line discusses, amongst several other things, how to use GNU Parallel to distribute your data over different machines. GNU Parallel is a great utility to parallelize any computation through the command line.
