2.3. Setting up your Manager Instance¶
2.3.1. Launching a “Manager Instance”¶
Now, we need to launch a “Manager Instance” that acts as a
“head” node that we will
mosh into to work from.
Since we will deploy the heavy lifting to separate
f1 instances later, the Manager Instance can be a relatively cheap instance. In this guide, however,
we will use a
running the AWS FPGA Developer AMI (be sure to subscribe if you have not done so. See Subscribe to the AWS FPGA Developer AMI).
Head to the EC2 Management Console. In the top right corner, ensure that the correct region is selected.
To launch a manager instance, follow these steps:
From the main page of the EC2 Management Console, click
Launch Instance. We use an on-demand instance here, so that your data is preserved when you stop/start the instance, and your data is not lost when pricing spikes on the spot market.
When prompted to select an AMI, search in the
Community AMIstab for “FPGA” and select the option that starts with
FPGA Developer AMI - 1.4.0. DO NOT USE ANY OTHER VERSION.
When prompted to choose an instance type, select the instance type of your choosing. A good choice is a
On the “Configure Instance Details” page:
First make sure that the
firesimVPC is selected in the drop-down box next to “Network”. Any subnet within the
firesimVPC is fine.
Additionally, check the box for “Protect against accidental termination.” This adds a layer of protection to prevent your manager instance from being terminated by accident. You will need to disable this setting before being able to terminate the instance using usual methods.
Also on this page, expand “Advanced Details” and in the resulting text box, paste the following:
#!/bin/bash echo "machine launch script started" > /home/centos/machine-launchstatus sudo yum install -y mosh sudo yum groupinstall -y "Development tools" sudo yum install -y gmp-devel mpfr-devel libmpc-devel zlib-devel vim git java java-devel curl https://bintray.com/sbt/rpm/rpm | sudo tee /etc/yum.repos.d/bintray-sbt-rpm.repo sudo yum install -y sbt texinfo gengetopt sudo yum install -y expat-devel libusb1-devel ncurses-devel cmake "perl(ExtUtils::MakeMaker)" # deps for poky sudo yum install -y python34 patch diffstat texi2html texinfo subversion chrpath git wget # install DTC. it's not available in repos in FPGA AMI DTCversion=dtc-1.4.4 wget https://git.kernel.org/pub/scm/utils/dtc/dtc.git/snapshot/$DTCversion.tar.gz tar -xvf $DTCversion.tar.gz cd $DTCversion make -j16 make install cd .. rm -rf $DTCversion.tar.gz rm -rf $DTCversion # get a proper version of git sudo yum -y remove git sudo yum -y install epel-release sudo yum -y install https://centos7.iuscommunity.org/ius-release.rpm sudo yum -y install git2u # install verilator git clone http://git.veripool.org/git/verilator cd verilator/ git checkout v4.002 autoconf && ./configure && make -j16 && sudo make install cd .. # bash completion for manager sudo yum -y install bash-completion # graphviz for manager sudo yum -y install graphviz python-devel # these need to match what's in deploy/requirements.txt sudo pip install fabric==1.14.0 sudo pip install boto3==1.6.2 sudo pip install colorama==0.3.7 sudo pip install argcomplete==1.9.3 sudo pip install graphviz==0.8.3 # for some of our workload plotting scripts sudo pip install matplotlib==2.2.2 sudo pip install pandas==0.22.0 sudo activate-global-python-argcomplete # get a regular prompt echo "PS1='\[email protected]\H:\w\\$ '" >> /home/centos/.bashrc echo "machine launch script completed" >> /home/centos/machine-launchstatus
This will pre-install all of the dependencies needed to run FireSim on your instance.
On the next page (“Add Storage”), increase the size of the root EBS volume to ~300GB. The default of 150GB can quickly become tight as you accumulate large Vivado reports/outputs, large waveforms, XSim outputs, and large root filesystems for simulations. You can get rid of the small (5GB) secondary volume that is added by default.
You can skip the “Add Tags” page, unless you want tags.
On the “Configure Security Group” page, select the
firesimsecurity group that was automatically created for you earlier.
On the review page, click the button to launch your instance.
Make sure you select the
firesim key pair that we setup earlier.
184.108.40.206. Access your instance¶
We HIGHLY recommend using mosh instead
ssh or using
ssh with a screen/tmux session running on your
manager instance to ensure that long-running jobs are not killed by a
bad network connection to your manager instance. On this instance, the
mosh server is installed as part of the setup script we pasted
before, so we need to first ssh into the instance and make sure the
setup is complete.
In either case,
ssh into your instance (e.g.
ssh -i firesim.pem centos@YOUR_INSTANCE_IP) and wait until the
~/machine-launchstatus file contains all the following text:
[email protected]:~$ cat machine-launchstatus machine launch script started machine launch script completed!
Once this line appears, exit and re-
ssh into the system. If you want
mosh back into the system.
220.127.116.11. Key Setup, Part 2¶
Now that our manager instance is started, copy the private key that you
downloaded from AWS earlier (
your manager instance. This step is required to give the manager access
to the instances it launches for you.
2.3.2. Setting up the FireSim Repo¶
We’re finally ready to fetch FireSim’s sources. Run:
git clone https://github.com/firesim/firesim cd firesim ./build-setup.sh fast
This will have initialized submodules and installed the RISC-V tools and other dependencies.
This will have initialized the AWS shell, added the RISC-V tools to your
path, and started an
ssh-agent that supplies
automatically when you use
ssh to access other nodes. Sourcing this the
first time will take some time – however each time after that should be instantaneous.
Also, if your
firesim.pem key requires a passphrase, you will be asked for
it here and
ssh-agent should cache it.
Every time you login to your manager instance to use FireSim, you should ``cd`` into your firesim directory and source this file again.
2.3.3. Completing Setup Using the Manager¶
The FireSim manager contains a command that will interactively guide you through the rest of the FireSim setup process. To run it, do the following:
This will first prompt you to setup AWS credentials on the instance, which allows
the manager to automatically manage build/simulation nodes. See
for more about these credentials. When prompted, you should specify the same
region that you chose above and set the default output format to
Next, it will create initial configuration files, which we will edit in later sections. Finally, it will prompt you for an email address, which is used to send email notifications upon FPGA build completion and optionally for workload completion. You can leave this blank if you do not wish to receive any notifications, but this is not recommended.
