I've been out of the game for quite a while, so this may be a known issue, or not an issue. Every time I try to crunch an astropulse work unit, it gets to approx. 22% complete, then seems to lock up. The "elapsed time" continues onward (highest I've seen is about 80 hours), but the "progress" and "remaining time" doesn't change. This has happened on more than three different ap work units. All my non-ap work units munch along nicely. Any ideas?

Oops, forgot to mention that it states (.133 CPU's + 1 ATI GPU)beside the work unit. I'm now thinking this isn't an astropulse issue, but a lack of my understanding of what (.133 CPU's + 1 ATI GPU) means. Still, why is this apparently locking up? I've never seen one go past approx. 22%.

Have you recently updated to win 8 ?
It seems you have some driver left overs.

Similar problem (task hang at ~21%) was discussed (17 Jun 2013) here:
http://setiathome.berkeley.edu/forum_thread.php?id=72035

Same parameters:
Windows 8: Core x64 Edition
AMD Radeon HD 7400/7500/7600 series (Trinity) CAL version 1.4.1741, 512MB
BOINC version 7.0.64 for windows_x86_64

The different - it was happening with SETI7 OpenCL r1843, not with Astropulse.

At the end of the long discussion the user solved the problem by installing older BOINC 7.0.28
http://setiathome.berkeley.edu/forum_thread.php?id=72035&postid=1385824#1385824


But the only AstroPulse task for computer 7067267 is one CPU task 'AstroPulse v6 v6.01' which is 'Aborted by user':
http://setiathome.berkeley.edu/results.php?hostid=7067267&offset=0&show_names=0&state=0&appid=12

Which contradicts with the "forgot to mention that it states (.133 CPU's + 1 ATI GPU) beside the work unit"

Which makes me believe the hang task for ATI GPU was not AstroPulse but 'SETI@home v7 v7.03 (opencl_ati5_sah)' like this:

I have a similar problem, but not on a GPU. Machine ID is 4630841, WU is
1332491653. This is stuck at 77% complete, but elapsed time continues to count up. Checking properties, this WU has been at about 12 hours CPU time for 2 days, although elapsed times is now over 47 hours. This machine gets shut down twice a day, to go to and from work. Anybody have any ideas?

A while ago, I reported several stuck ATI tasks (both V7 and AP) on this thread: Stuck AstroPulse v6 v6.06 (opencl_ati_100) task. I am now having similar problems with AP CPU tasks (AstroPulse v6 v6.01) on the same host. And, strangely enough, the problem with stuck GPU ATI tasks has pretty much gone away. As with the stuck ATI tasks, when an AstroPulse v6 v6.01 gets stuck, I am usually able to get it going again by restarting BOINC - but sometimes I also need to suspend all GPU tasks first and then restart BOINC.

If I had the time at the moment, I'd run this over the BOINC and s@h codebase.

I get the same hanging action for astropulse and v7 using a hd6570 gpu. I am using win 8.1. I hate to give up on seti AGAIN but I am not going to have any choice unless someone has a solution. I am using the latest BOINC. Any help?
Thanks. I will have to go back to collatz or moo!wrapper if not. Thanks for reading this.
