🛠️ Installing Intel Parallel Studio on Ubuntu
Intel Parallel Studio is a powerful tool for optimizing and parallelizing code on Ubuntu. In this guide, we will walk you through the step-by-step process of installing Intel Parallel Studio on your Ubuntu system.
Step 1: Installing Required Packages
Before we begin the installation process, there are some packages that need to be installed. Open a terminal and run the following command to install the necessary packages:
sudo apt-get install package1 package2 package3Optionally, you can also set up a 32-bit environment if you plan to compile your own code in a 32-bit way. However, this is not necessary for compiling Quantum Espresso.
Step 2: Decompressing the Package
There are two ways to decompress the Intel Parallel Studio package. The first method is using the command line. Open a terminal and navigate to the folder where the package is located. Run the following command:
tar -xf package-name.tar.gzThe Second method is using the graphical user interface. Simply right-click on the package and select "Extract Here". This will create a new folder containing the installer.
Step 3: Running the Installation with Command Line
To run the installation process with the command line, open a terminal and navigate to the newly created folder. Run the following command:
./install.shIf you prefer to use the user interface for installation, run the following command:
./install_gui.shStep 4: Selecting Installation Preferences
During the installation process, you will be prompted to select various preferences. Firstly, you need to accept the license agreement. Next, the installer will perform some verification.
If you are using Ubuntu 19, you may encounter an "unsupported operating system" message. However, this can be ignored and clicking "Next" will proceed with the installation.
You will also need to provide the serial number associated with the package. Students and open-source developers can obtain a serial number for free.
Step 5: Customizing the Installation
The installer will ask you to choose the installation destination and the components to install. By default, the installer will install all components, but if you are concerned about space, you can customize the installation.
In the customization options, you can deselect components that are not required for compiling Quantum Espresso. However, it is recommended to keep the C++ and Fortran compilers, the Intel Math Kernel Library (MKL), and the MPI library.
Additionally, you can reduce the installation size by deselecting the 32-bit support if you don't need it.
Step 6: Completing the Installation
Once you have customized the installation, click "Next" to proceed. The installer will show you the total space required for the installation. If you have enough space, it is recommended to install all components.
After clicking "Install", the installation process will begin. This may take some time, so sit back and relax.
Step 7: Initializing the Tools
After the installation is complete, you need to initialize the tools before you can start using them. Open a terminal and navigate to the installation directory. Run the following command to set the environment variables:
source /path/to/intel/parallel_studio/vars.shAlternatively, you can add this command to your .bashrc file to automatically set the environment variables every time you open a terminal.
🚀 Compiling Quantum Espresso using Parallel Studio
Now that you have Intel Parallel Studio installed and the tools initialized, you can proceed with compiling Quantum Espresso.
To compile your code using the Intel Fortran compiler, navigate to the directory containing your Quantum Espresso code and run the following command:
ifort -V -o executable input.f90Replace executable with the desired name of the output executable file and input.f90 with the name of your Fortran code file.
Similarly, you can use the Intel C compiler (icc) for compiling C code.
Conclusion
Congratulations! You have successfully installed Intel Parallel Studio on your Ubuntu system and learned how to compile Quantum Espresso using this powerful tool. Now you can optimize and parallelize your code to enhance its performance.
Remember to explore the various features and capabilities of Intel Parallel Studio to make the most out of this tool.
