Message 1778382 - Posted: 12 Apr 2016, 18:04:28 UTC

Happy Yuri's Night #55, the 55th anniversary of Yuri Gagarin's historic first space flight on April 12, 1961.

In celebration, we're starting distribution of Breakthrough Listen data from the Green Bank Telescope today. No intervention is necessary on your part. The main difference you will see is a change in your screen saver graphics, if you have them running. We'll still be distributing Arecibo data as well, so that won't change.

The Breakthrough Initiative is also distributing raw data in multiple formats, so you can write your own analysis code if you'd like.

You can read about it in this press release.

Fantastic news... thank you!

Is there any estimate on what volume of workload is going to be released in comparison to the current MB workload from Arecibo?

I'd expect about 50/50 for the time being.

Unexpectedly large amount... excellent: doubled workload (hope the infrastructure can keep up.)

Also it was noted in NC that much of this may be VLAR due to being targeted so may be minimal(?) GPU involvement.

Great! Thanks for your efforts and kudos to those responsible for the additional funding. :)

Could someone please explain the information in the new file names on the SSP?

Just out of curiosity. for Breakthrough - One day of listening what is now ongoing = how much data like on average ? ( what will be going through )

Two thumbs up for one of humanity's luckiest men, and two thumbs up for the eagerly awaited Green Bank data! :D

May we all live long and prosper :)

Here's to hoping someday someone can figure out a way to make that happen. In the meantime, looks like the need for some CPU heavy rig building.

We've got 120,000 GBT workunit waiting to go, but a few hundred thousand Arecibo units to chew through before they get to the front of the line.

You know what they say...

Not that I know how the BOINC system works, but isn't there some way to use "plan class" or some equivalent?

What would be a possible workaround in the interim (until someone cracks the issue of why VLAR/VHAR(?) bogs CUDA pulse detection) is a default-off setting in SETI@Home Preferences ie "Accept VLAR work units on NVidia CUDA (warning: these units may complete very slowly and cause the computer to become unresponsive)"

(Those with both dedicated crunchers and workstation computers they actually use could prevent the ones they use from slowing down by adding "home"/"school"/"work" separate preferences, putting the dedicated crunchers in one "location" setting with accepting VLAR on CUDA on, and the workstations in another "location" setting with it off.)

Here's to hoping someday someone can figure out a way to make that happen. In the meantime, looks like the need for some CPU heavy rig building.


I'll have to look at it that if the work that my NVidia GPUs do frees up CPUs and AMDs to do the work to make The Great Discovery, it's still worth it... I'll be happy if anyone makes it. :^)

To be able to run VLARs on my Nvidia GPUs I'd live with a "health warning" as suggested by Mr.Kevvy. Although I suspect some would just ignore the warning and moan like crazy.

Congratulations to you, Eric, and the entire team at Berkeley. It is a major milestone, worthy of a celebration.

I look forward to the day when data from the southern skies start being processed by the SETI@Home project.

I'm terribly sorry to read about your kitty. Surely ultra advanced aliens somewhere out there, don't have to live with such awful things happening. Maybe someday, we'll get really really really lucky, and such aliens will radio us an advanced science which yields immortality. I can wish anyways.
