How to install the Virtual Machine for OpenMP/Cilk/MPI Programming on your Laptop/Desktop

• Download and install VirtualBox.
• Download the customized OpenMP/Cilk/MPI Xubuntu virtual appliance (4 GB): https://www.scs.carleton.ca/~dehne/vbox/Parallel-FD-2022.ova

• Start VirtualBox. The “Oracle VM VirtualBox Manager” window opens.
• Create a virtual machine (needs to be done only once): Go to “File” menu and select “import appliance”. Select the downloaded “.ova” file and click “Next”. A window “Application Settings” appears. The virtual machine is pre-set to use two processor cores. Change the number besides “CPU” to match the number of cores you have. Then click “Import”. It may take a few minutes for your computer to build the new virtual machine. When finished, a new virtual machine appears in the left column of the “Oracle VM VirtualBox Manager” window.
• To start the virtual machine, select the VM entry in the “Oracle VM VirtualBox Manager” window and click “Start”. A new window opens and your machine starts running.
• The Ubuntu virtual machine will boot directly into the main account (no login required; you have superuser status; login ID “student”, password “student”.).
• To close the VM, simply close the VM’s window. Select “Save the machine state” from the popup window for faster re-start of the VM.
