SETI@home yields to pressure to curb cheating

Administrators of the alien-hunting distributed computing experiment SETI@home have announced they will crack down on cheats who rort statistics on computing power lent to the project. The announcement follows a united protest from the chief contributors.

SETI@home director David Anderson announced SETI@home would do its best to investigate users returning suspiciously high amounts of work and delete their accounts if it uncovered solid evidence of cheating.

The announcement comes after over 800 of the project's keenest contributors signed a petition demanding that SETI@home administrators act to curb the rorts.

The petition was organised last week after veteran "cruncher" and cheat-hunter, Max Nealon, exposed a massive increase in the amount of illegitimate work units being returned to SETI@home.

Nealon said he approached the media because he believed that cheating was dominating the work returned by the project's top contributory sources, leading to a vast overstatement of the project's power.

"When talking to sponsors about their four million users - 200,000 active, 4,000 producing more than 90 percent of the work -- they are over-stating their power," said Nealon.

Nealon revealed startling statistics about cheating from SETI@Netherlands team leader Rick Groenewegen. Groenewegen estimated that accounted for an estimated 41 percent of the eight million work units on the SETI@Netherlands tally were produced a handful of cheats that had infiltrated the team.

Groenewegen, who has sinced re-confirmed the statistic' accuracy said, the situation was very disappointing as the vast majority of the team were honest crunchers.

According to Groenwegen there have been many instances of cheating throughout the project's three-year history, and across many teams.

Groenwegen said that the community behind the project was starting to grow weary of being ignored by Berkeley and that the latest revelations had forced people to rethink their decisions to continue contributing to the project.

"People were getting sick and tired of Berkeley ignoring requests from the community," said Groenwegen. "There were indeed people that were willing to go to other projects where the staff would listen to them".

Some users have trivialised the cheating problem as a storm in a tea cup. They say that the project's organiser should remain focused on preserving the integrity of the experiment's scientific method not chasing cheats, however Groenwegen bemoans that reasoning.

"It is true that the cheats that were used by the 'recent' cheat[s] didn't affect the science, but projects like SETI@home are powered by the effort of the volunteers.

"If those volunteers think it's a big problem than Berkeley should consider it a big problem too," he said.

When asked why SETI@home had decided to act on the problem now Anderson said that he just had found some "spare time" to work on it.

"We know that individual and team statistics are very important to many of our users, and we'd like to keep accurate statistics," said Anderson in his statement.

Anderson said last month that SETI@home's project designers were in the midst of finalinsing a deal to secure new funding.

But Anderson said that the administrators were still hampered by man-power problems and said addressing the cheating problem would have to be prioritised against the rest of the project's goals.

For now he has asked contributors to be patient and asked for their assistance to make SETI@home's successor, Berkeley Open Infrastructure for Networked Computing (BOINC), more cheat-resistant.

"Please bear with us until BOINC is released. BOINC is open-source, so programmers can help us by reviewing its cheat-prevention system," said Anderson.

Some users have called on SETI@home to give team leaders more power to manage accounts. However Groenwegen believes this would be a band-aid measure that would place too much responsibility on the team leaders. He believes structural changes need to be built in to the server software.

"It would be helpful, but my opinion is that if you do that you're not working for a solution. If you add an option like that, it's just a 'quick-fix'," he said.

    What's a team leader? I've been a part of SETI for some time, but didn't know I have a "team leader." I leave my computer on all day and trust my firewall to keep hackers from using my broad-band access. Currently I've completed 182 data units with 2890+ hours of computer time. What difference does "cheating" make if the data units are being processed.

    I think curbing the cheating is a very good idea, one of my partners is pumping a WU in about 26 minutes and my system is almost double his, and I am only pumping one every 4 hours. I know some may not think its a very big deal but the more problems the program has, the less likely it is to get more client contribution. Mind you this is only my opinion.
