To run heavy programs more efficiently, users can utilize online computing resources. Many universities offer supercomputing facilities, but access may require funding or student status. Traditional computing services like Compuserve have declined with the rise of personal computers. Current options for cloud computing include major providers like Google Cloud, AWS, and Microsoft Azure. Users can set up accounts with these services to run their code remotely. Specifically, for running a GitHub repository on Azure, users can upload their code and execute it, such as running a Python script from a repository designed for cosmological parameter estimation.
