320 mini computers make mega mainframe

A supercomputer capable of searching the outer limits of space for alien life and helping stop the spread of COVID-19 is located close to home at Southern State Community College, where computer science students learned valuable knowledge and skills in their field by building it themselves. “This is an amazing example of student-selected, project-based learning,” said Computer Science Professor Josh Montgomery. “This project took a wide range of skills to complete.”

According to Montgomery, the supercomputer is composed of 320 Raspberry Pi 3 mini computers with access to 1,280 processing cores and 320 gigabytes of Random Access Memory storage, making it a powerful device with many capabilities. Montgomery said the computer has crunched data for programs like the Search for Extraterrestrial Intelligence, which is an effort to detect evidence of technological civilizations that may exist elsewhere in the universe, particularly in our galaxy, according to its website.

I have installed the necessary GNOME Desktop packages. Installing GNOME Desktop on CentOS 6 on a console before installing xrdp.

But the solution is quite simple. You need to install the tigervnc-server package and just the tigervnc only.

# yum install tigervnc-server

Restart the xrdp again.

# service xrdp restart
