SETI anyone?

Recommended Posts

this may have been posted in the past, but i haven't seen it recently. how many people here are running the SETI program? If you are and weren't aware of it, there is a group called the Skydiver Alien Network. i am a member, and i see a few other familar names on the list as well. would anyone be interested in starting a dropzone.com group? if you are involved now, how many work units have you completed?

I stopeed running SETI after I got in trouble for running the Solaris command line version on the production servers over the weekend. I think the unites were being processed about once an hour or something...

geez, that's smokin'! my home system takes 6-10 hours per, i was running it at work on an hp l2000 system pretty quick as well. it was a test box at the time, so nobody cared.

Search for Extra Terrestrial Intelligence....There is the VLA (Very Large Array) of radio Telescopes that was being used to listen for radio or other forms of EM communiction thought to come from an extraterrestrial civilization. Now they use the Mount Arecibo (sp) telescope in Puerto Rico. One of the largest in the world. They collect so much data, that they can't analyze it all. So, they set up SETI @Home. The basic principle is simple. If you network a lot of small computers, you can effectively create a huge one. So, they send out a program which you can download for free, they send you a chunk of data, which your computer analyzes, using Fast Fourier Transfroms ( used to find patterns in data), then sends it back. Then they send you another chunk of data....etc. Here's the website http://www.setiathome.ssl.berkeley.edu/

Yeah, it was an Sun 64 processor server they used to crunch some pretty complex numbers (breast cancer research).

FYI, Having the Unix Admin rip you a new one in the cafeteria is a very humbling experience.
Then again this was the same guy who put a personal linux box on the network to get around some closed ports (Tribes and Quake mostly) only to realize that it had taken over the gateway functions for the whole campus. Can we say OOPS?

if you look at your profile , there should be something there about a team or group. The group i belong to is the skydiver alien network, whose stated purpose is to track down an alien so that we could be the first to jump a ufo. the team site is here.

Uh... I guess so :) I was a desktop support guy there, but one of my friends who was also a sysadmin was telling me the specs on that puppy. There were 4 seperate servers clustered together, but I thought I was smart and telneted into a single node to run it. Who would have thought that people actually read the logs, Rumor had it that it went something like "What is seti and WHY is it using 98.7% of the CPU cycles? OOOOO look Mr Lum is logged in and running that process, KILL PID XXXXX...

yeah, but seti is not multi-threaded as far as i can tell... it will only run on one processor. i'm running it on a dual processor test box right now and it will run one instance per processor. if you try to run more, it swaps a lot and doesnt' accomplish as much. you must have been hogging one processor and someone noticed.

I played with SETI for solaris, i thought there was a way to make it user more then one cpu, maybe not. But y ou could always run more then one instance. Swapping probablem wouldn't be an issue with the machine in question. If it had 64 procs then it probably had 64gb of ram as well, as that is the max configuration. Even split into domains as Lummy said it was, a single board domain would still be 4cpus 4gb. Those are pretty sweet machines, they were sun's top of the line until about a year and a half ago, i think. I was stoked the first time i got to play with one.
