Great news, Eric! Anything that enhances our search is welcome indeed.
Do hope that the servers can handle the increased bandwidth that it's going to take.

Is the double size the new standard then?


Double size is the new standard for both Arecibo and GBT (and eventually Parkes). Unless UC complains about the extra traffic. I don't think they'll even notice it.


I don't suppose we can get a bandwidth graph?

Dang, I wish I knew of one. We lost those a long time ago here.
I used to keep them in an open window all the time.
They were a very good tool when one is trying to monitor how the servers are doing.
Either not possible or impractical to add one to the colo, I suppose.
And probably not considered necessary or useful enough for the project to justify any expenditure of time or effort on it.

Thanks for the info Eric. No problems with the *KIC* tasks, and since I was running the "double sized" tasks in Beta testing, I already knew that those would work fine too.
Keep 'em coming :-)

I must admit, the message addition only seems to have been for a couple of tasks. Since I restarted BOINC I haven't seen it again. But then again, I haven't had any more KIC8462852's either. :(

Got another couple of blcs with the header, but this time HIPs.

I will run a Wireshark capture to see if this header is actually sent to the server.
And if this is a buffer thing, then why only on these new tasks and why always that one sentence?

Edit: having made a capture, and gone through it, I don't think this header is actually sent. The capture doesn't make note of it.

For those who didn't recognize the name KIC8462852 in their work unit names, this data comes from GBT observations of Tabby's Star (aka Boyajian's Star, aka WTF-0001, aka the Weirdest star in the galaxy). This is not yet the full data set, which lives at Penn State, it's some test on-target/off-target observations that we're checking out.

You might also notice another change. We've doubled the size of our work units which will reduce our quantization noise by 34%, and, depending on the strength of other noise sources, could give us as much as double that as a sensitivity increase.

Why did we stop crunching the *DIAG_KIC* data? They seems to be put in some pause mode when it comes to the splitters, and we're only doing *HIP* data again.

The BL splitters *always* seem to switch to the latest batch of data loaded, and leave behind whatever they were working on before until the new batch is complete. I'm surprised you haven't noticed that before.

If the download size has doubled to roughly 766 kilobytes does that mean that the upload sizes have increased as well?

Nope.
Upload file sizes remain the same.

Thanks Grant. Can you or anyone confirm for me what the download size is?

Is there a project you can start to process data collected from the "Tabby's Star (KIC 8462852)" on the SETI site. Like we do for SETI@home??? Our founder Boomer (User ID 9091807) from the New Mexico Group, said that there is no more data being collected come out of the Arecibo Radiotelescope. Are we are just getting the last of the Work Units on SETI.

Thanks in advance.

Thanks Dr. Korpela. :)

I've been an avid helper between a number of different computers and clients over the years and I really am excited by what you and everyone who's helped you have done with this project. Will be with you until the ultimate goal is reached as long as I have the means and ability to be.

There's still a large mountain of "old" work to re-process from Arecibo, plus all the work that is coming in from the Breakthrough Listening Project. So no shortage of work to do. Plus there's at least one more telescope coming on line, so don't panic.
