How to install Pythia 8 and Fastjet on Linux
This is a tutorial about how to install Pythia 8 and Fastjet. After that i have explained two methods to link pythia8 to fastjet. I have tried to keep it simple and easy so that first time linux users can also understand it.
First of all you need to install g++ if you don't have yet.
For Ubuntu, Debian, Mint :
For Redhat, Scientific Linux, Fedora:
You can also install that using source file or rpm.
Now we will install Pythia8 and Fastjet.
Pythia 8 :
1. Download the file
2. Now to extract it open your terminal. Move to the directory where you have placed the
After moving to that directory excract that file with
First of all you need to install g++ if you don't have yet.
For Ubuntu, Debian, Mint :
sudo apt-get install g++
For Redhat, Scientific Linux, Fedora:
yum install g++
You can also install that using source file or rpm.
Now we will install Pythia8 and Fastjet.
Pythia 8 :
1. Download the file
pythia8150.tgz (or pythia81xx.tgz
) to a suitable location from its website .2. Now to extract it open your terminal. Move to the directory where you have placed the
pythia81xx.tgz
after downloading. If you have placed that in your "software" (/home/username/software/ ) folder, then you can do this by :
cd software
After moving to that directory excract that file with
tar xvfz pythia8150.tgz
Then it will create a directory. Now move to the directory by the command
Now type these commands (and press enter) step by step:
You have installed Pythia8 !
Fastjet
At first visit Fastjet website and download the source file which looks like " fastjet-x.x.x.tar.gz " where x.x.x represents version number. Now follow the earlier steps to like Pythia8 to extract the source file. Rename it as "fastjet". Now move into the folder fastjet. The type the following commands(and press enter) step by step.
You have installed fastjet !
Linking Pythia 8 to Fastjet :
Open your holy terminal once again. Move to the Pythia directory as you did earlier. Now move to the directory " examples " with command " cd examples". Then type the command and hit enter:
Generaly the directory path is like : /home/username/something-or-not/fastjet/
If its successful then in terminal you will see something like " found fastjet version 2.4.3 " .
Done ! Now, from you from your pythia directory open pythia worksheet (a pdf file ) and it will guide you to the compilation process. But if you follow this process you may have to keep your source file in the examples folder and in the terminal you need to move to the "examples" directory with "cd" command to run and compile those programs. But there is another way. Check out the method below.
MakeFile :
If you want to keep your cpp source files, compile and run from some other folders then you need a Makefile in the directory where you want to compile and run. Download the file below .
Makefile
Then follow the three steps below.
1. Change the value of PYTHIADIR and FASTJETDIR . Set your own directory path of pythia and fastjet.
2. At the end of the file you will find a code
Replace those red colored names with your source file's name.
3. In your source file instead of " Pythia pythia; " you need to type
Pythia pythia("/home/mushfiq/collider/pythia8150/xmldoc") ;
You need to change the red colored path as your own.
Now from the terminal move to the directory where you have placed the source file (say jet.cc) and the Makefile. Now type "make" and hit enter. Done ! To get the output of jet.cc we can use :
Now output is saved in jet.out . You can click on the file to open or simply type in terminal "gedit jet.out " and hit enter. BTW, if you use this method with Makefile then you don't even need to link pythia to fastjet with ./configure --with-blah-blah ... !
Ahh! We are done !
N.B. I am not an expert of these stuffs. There may be better ways. But this is just how i fixed mine.
cd pythia8150
Now type these commands (and press enter) step by step:
./configure
make
You have installed Pythia8 !
Fastjet
At first visit Fastjet website and download the source file which looks like " fastjet-x.x.x.tar.gz " where x.x.x represents version number. Now follow the earlier steps to like Pythia8 to extract the source file. Rename it as "fastjet". Now move into the folder fastjet. The type the following commands(and press enter) step by step.
./configure
make
make install
You have installed fastjet !
Linking Pythia 8 to Fastjet :
Open your holy terminal once again. Move to the Pythia directory as you did earlier. Now move to the directory " examples " with command " cd examples". Then type the command and hit enter:
./configure --with-fastjet=/your-fastjet-directory-path/
Generaly the directory path is like : /home/username/something-or-not/fastjet/
If its successful then in terminal you will see something like " found fastjet version 2.4.3 " .
Done ! Now, from you from your pythia directory open pythia worksheet (a pdf file ) and it will guide you to the compilation process.

1. Change the value of PYTHIADIR and FASTJETDIR . Set your own directory path of pythia and fastjet.
2. At the end of the file you will find a code
g++ -o jet jet.cc
Replace those red colored names with your source file's name.
3. In your source file instead of " Pythia pythia; " you need to type
Pythia pythia("/home/mushfiq/collider/pythia8150/xmldoc") ;
You need to change the red colored path as your own.
Now from the terminal move to the directory where you have placed the source file (say jet.cc) and the Makefile. Now type "make" and hit enter. Done ! To get the output of jet.cc we can use :
./jet > jet.out
Now output is saved in jet.out . You can click on the file to open or simply type in terminal "gedit jet.out " and hit enter. BTW, if you use this method with Makefile then you don't even need to link pythia to fastjet with ./configure --with-blah-blah ... !

Accepted !!!
A good news! I have been accepted in Theoretical Physics Department masters program. I wrote a post earlier where i said about my low possibility of getting accepted. But i have been accepted. So i am happy!
GRE words suck!
Its really hard to memorize GRE words. I have one month left before the test and i am reading those freaking words and forgetting. More important thing is the more i read words the more my brain becomes lazy and it seems i am turning into a thicko. It does not seem to work well. I hope and pray that this shitty GRE will go well. Next few weeks will be really stressful !
