Ethics in Action Using grid computing, researchers at the University of Chicago, Northern Illinois University, Argonne National Laboratory, and the Max Planck Institute for Gravitational Physics in Germany simulated how black hole collisions affect gravity. Personal computers also can join millions of other computers throughout the world when they are connected to the Internet and have idle processing time. While grid computing turns inactive computer time into computational power, some critics believe some grid projects are immoral, may compromise intellectual property, and may undertake work that for-profit companies should perform. Visit Grid.org, the Open Grid Forum (ogf.org), the Globus Alliance (globus.org), and other Web sites to learn about current grid computing projects. Should for-profit companies pay grid participants for their computer time? Is data security compromised? Who sets standardization guidelines? How will companies track network resources? Write a report summarizing your findings, and include a table of links to Web sites that provide additional details.
