Message 1910976 - Posted: 5 Jan 2018, 23:00:46 UTC - in response to Message 1910959.  

Since the statement has been made there is no more Arecibo work in hopper, or available, I would say the future of this thread is also in grave doubt.........

Plenty of AP resends still to come, then people can discuss how long it was since they last had an AP WU, and how much Credit they gave compared to MB..
I reckon it's got years of life, even if there is no more AP data to be split.

We can also complain about why nobody is making an app for AP for work from GBT or Parkes.
That should keep the thread alive for years too :-)

I'm reasonably sure that it was mentioned they wanted to do AP for GBT data as well.
The first step requires the guys in the lab have the time to write the new splitter code, or have the budget for interns to tackle it.
Until that is done working on an app to processes non existent workunits wouldn't be much of a priority.

I thought it was Raistmer that wrote the code? Or did he just modify it to run on OpenCl??

Multiple authors over time for the Windows and Linux apps.

AstroPulse v7.08 for Linux
Linux 64 bit, Rev 2751, OpenCL version by Raistmer, GPU mode
V7, by Raistmer ported to Linux by Lunatics.kwsn.net team.
by Urs Echternacht
ffa threshold mods by Joe Segur

AstroPulse v7 Windows x86 rev 2887, V7 match, by Raistmer with support of Lunatics.kwsn.net team.

OpenCL version by Raistmer

ffa threshold mods by Joe Segur
SSE3 dechirping by JDWhale
Combined dechirp kernel by Frizz

But as Hal has said, not much point in developing a new V8 AP app if there aren't any V8 AP tasks being split. The splitter code is written by the project scientists. We would need to use some of our donation pledges to hire a temp intern to write the new splitter code.

Am I taking too simplistic a view when I say the code should be pretty similar provided the input data is just from a different source? Go ahead, slap me if I'm asking a 'stupid question'.

I think it is not that easy. Best people to ask are the Seti Beta testers who were around for the MultiBand transition from V7 to V8. I would think the process to be similar with whatever monkey wrench the difference in file format for GBT tasks will throw in.

Even for those cases where things are mostly the same, just some minor differences, there are times where those very slight differences can make the difference between requiring minor changes, and having to start from scratch, or somethings somewhere in between.

IIRC a grad student wrote the code some years ago,

Looking at my current WUs, it appears i scored a AP WU yesterday when I wasn't looking.
Massive boost to my presently depressed RAC, now it's not falling as fast as it was...

Anyone else notice problems with the AP validators ?

https://setiathome.berkeley.edu/workunit.php?wuid=2803014238

Not a big issue as it will probably sort itself out when the deadline arrives.
