Welcome to the world's largest supercomputing gridWith 20PB of storage, and more than 280 TFLOPS of computing power, TeraGrid combines the processing power of supercomputers across the USABy David Strom, Computerworld A unique US Government-funded computing effort is making it easier for corporations to access the largest-scale computers on the planet. Dubbed TeraGrid, the effort spans nine different academic and government institutions and has reached a critical mass this year. Read More

Radar Blanking We wanted to bring everyone up to date on the interference issue that Eric described in this blog entry . Eric, while working on the multibeam client in the beta project had noticed that a large number of results were overflowing. Too many signals were being detected, a sign that the data contained a large amount of radio frequency interference (RFI). The interference was in the form of pulses. The task at hand was to track down the source of the RFI and then make it "go away" by either removing the source or, failing that, scrub it from our data. At this point we were not sure if this was real RFI (a signal entering the receiver) or some sort of interference within the data recorder or intervening electronics that ended up looking like RFI. We sampled our data (collected over many months and many different pointings) and found that the RFI pulses were always present. So the source was very local. Starting at the end of the data acquisition chain and working backwards we first asked if the recorder software had a bug that caused it to introduce these pulses. No, independent software also saw them. Was it a hard drive or power supply issue? Was it a problem in the front end electronics? One by one we eliminated these possibilities. Time to ask the Arecibo Observatory (AO) staff for help. |
Member of the Month Interview: -Beerdrinker It´s that time of the month again. And as always we exceed our boundries to give our teammates the best! The teammate you are about to meet, is a regular poster on the MB. In fact he is also a member of the newsletter crew! So without further delay I proudly introduce..... |

SETI.USA encourages its members to participate in the project of their choice. Now that we have accomplished the team's original goal of being #1 in SETI@home credit in ALL BOINC projects is valuable to the team's future success.
RAM: 1GB of RAM is suggested, as the simulation takes up typically between 150-450MB of memory. Disk space: 500MB of hard disk space should suffice. |

SETI.USA would like to thank ALL of it's dedicated members and offer CONGRATULATIONS to all those who achieved significant personal milestones in the month of June. As you all know, we are growing exponentially. We now have: Combined: |
The month of June was a good month for Users of The Day. We had a total of 33 awarded which is nine more than we got in May. Dr. Dan T. Morris lead the team with a total of 7 UoTDs for the month and we totally dominated Riesel Sieve with a total of 13. We are still currently 5 away from taking the #9 spot away from Belgium and I think we stand a really good chance of doing so before the next newsletter. |
