It hasn’t yet found what it set out to, but there’s still hope. As of 16 October 2005, approximately one-third of the processing for the non-BOINC version of the software was performed on work or school based machines. As many of these computers will give reduced privileges to ordinary users, it is possible that much of this has been done by network administrators. There were plans to get data from the Parkes Observatory in Australia to analyze the southern hemisphere.
Frank's insights led to optical SETI, SETI@home, and most recently, while in his 90's, Frank helped pioneer PANOSETI. On March 31, 2020, UC Berkeley stopped sending out new data for SETI@Home clients to process, ending the effort for the time being. The program stated they were at a point of "diminishing returns" with the volunteer processing and needed to put the effort into hibernation while they processed the results. To date, the project has not confirmed the detection of any ETI signals. However, it has identified several candidate targets , where the spike in intensity is not easily explained as noise spots, for further analysis. The most significant candidate signal to date was announced on September 1, 2004, named Radio source SHGb02+14a.
Project future
The SETI FORWARD Fund is an endowed fund created by Lew Levy, and other donors including Dane Glasgow, Jill Tarter, Andy Fraknoi and many more. The SETI FORWARD Fund will support undergraduate student research activities. Each summer, undergraduate students complete internships alongside SETI research scientists – currently at both the SETI Institute and the Berkeley SETI Research Center. Too few of these students pursue science careers in SETI research. SETI FORWARD seeks to show undergraduates these promising pathways, by providing opportunities that bridge the gap between these SETI internships and careers in SETI science and research.
The SETI Institute has recently created the SETI FORWARD Program, supported by a modest endowed fund. The mission of SETI FORWARD is to encourage the next generation of SETI scientists - undergraduate students. SETI FORWARD seeks to provide an incentive to pursue this field of study, along with mechanism for connecting promising students with SETI researchers, all who share a passion for the fundamental question - Are We Alone in the Universe? The intent is to establish a long-term succession plan focused on undergraduate students with the specific aim of bringing new people into the field of SETI research and establishing SETI ambassadors to promote SETI to a new generation. Congress canceled NASA’s SETI program in 1993, and the nonprofits that picked up the slack are always searching for funding in addition to alien life. SETI@home is a scientific experiment, based at UC Berkeley, that uses Internet-connected computers in the Search for Extraterrestrial Intelligence .
In other projects
Berkeley Space Science Lab has found ways of working with small budgets, and the project has received donations allowing it to go well beyond its original planned duration, but it still has to compete for limited funds with other SETI projects and other space sciences projects. On May 3, 2006, new work units for a new version of SETI@home called "SETI@home Enhanced" started distribution. Since computers had the power for more computationally intensive work than when the project began, this new version was more sensitive by a factor of two concerning Gaussian signals and to some kinds of pulsed signals than the original SETI@home software. This new application had been optimized to the point where it would run faster on some work units than earlier versions.
The project has had to shut down several times to change over to new databases capable of handling more massive datasets. Hardware failure has proven to be a substantial source of project shutdowns, as hardware failure is often coupled with database corruption. In one documented case, an individual was fired for explicitly importing and using the SETI@home software on computers used for the U.S. state of Ohio. Some users have installed and run SETI@home on computers at their workplaces; an act known as "Borging", after the assimilation-driven Borg of Star Trek.
Status message
However, in the overall long-term views held by many involved with the SETI project, any usable radio telescope could take over from Arecibo , as all the SETI systems are portable and relocatable. The SETI@home volunteer computing software ran either as a screensaver or continuously while a user worked, making use of processor time that would otherwise be unused. Data was merged into a database using SETI@home computers in Berkeley. Interference was rejected, and various pattern-detection algorithms were applied to search for the most interesting signals. Scientific meetings/conferences are great places to showcase your SETI internship work to potential employers and graduate programs, to network, and to get a broader view of the field of study. Since the program is new in 2019, income from the endowed fund has not yet been generated, but the SETI Institute has set aside some limited funding this year to sponsor meeting travel for one intern to present their work .
Since its launch on May 17, 1999, the project has logged over two million years of aggregate computing time.[as of? ] On September 26, 2001, SETI@home had performed a total of 1021 floating point operations. It was acknowledged by the 2008 edition of the Guinness World Records as the largest computation in history. With over 145,000 active computers in the system (1.4 million total) in 233 countries, as of 23 June 2013, SETI@home had the ability to compute over 668 teraFLOPS.
What is SETI@home?
Credit is only granted for each returned work unit once a minimum number of results have been returned and the results agree, a value known as "minimum quorum" . If, due to computation errors or cheating by submitting false data, not enough results agree, more identical work units are sent out until the minimum quorum can be reached. The final credit granted to all machines which returned the correct result is the same and is the lowest of the values claimed by each machine. SETI@home users quickly started to compete with one another to process the maximum number of work units. The competition continued and grew larger with the introduction of BOINC.
SETI@home searches for possible evidence of radio transmissions from extraterrestrial intelligence using observational data from the Arecibo radio telescope and the Green Bank Telescope. The data is taken "piggyback" or "passively" while the telescope is used for other scientific programs. The data is digitized, stored, and sent to the SETI@home facility. The data are then parsed into small chunks in frequency and time, and analyzed, using software, to search for any signals—that is, variations which cannot be ascribed to noise, and hence contain information.
But the remaining participants’ computers are hundreds or thousands of times more powerful than they were in 1999. “When we started, we designed our work units—our data chunks going out to people—to be something that a typical PC would be able to finish computing in about a week, and a current GPU will do those in a couple of minutes,” Korpela says. SETI@home is now available via an Android app that’s used by about 12,000 participants, and even smartphones smoke turn-of-the-century desktop computers in processing speed. As SETI@home spread, a few of its more zealous acolytes ran afoul of the workplaces where they installed it, which the program’s creators advised users not to do without permission.
To point telescopes at us continuously, which means that the aliens would need to know we’re here. Because human radio transmissions started only a century or so ago, any life farther than 100 light years away would have no way of knowing we’re here. And any life farther than 50 light years away wouldn’t yet have had time to send a message back to Earth. Around the time the movie Contact came out in 1997, Kevin D., a governmental IT support and procurement employee in Toronto, saw a notice on a technical news site about a piece of software that was being developed by researchers at the University of California, Berkeley. It also signaled the advent of a productive and unprecedented citizen-science project that continues today, 20 years after it launched in May 1999.
The second of these goals is considered to have succeeded completely. The current BOINC environment, a development of the original SETI@home, is providing support for many computationally intensive projects in a wide range of disciplines. Provide undergraduate student bursaries to organizations engaged in SETI research to help them obtain and nurture new talent in the field.
