Hi Eric,
Get Decics with Bounded Discriminant v3.04 was also getting calculation errors, but I found also some finished/valid results.

But the new one "Get Decics with Bounded Discriminant v3.05" is running good. No errors found. All results are valid.
Could just check on one of my hosts the uploaded results.
one additional point, the runtime of the 3.05 is nearly the same like the CPU time.


one point regarding the temp files, why is there the problem?
normally boinc apps should use the slot dir for temp files. In this case two running apps using the same temp file name should not get a conflict.

one additional point, the runtime of the 3.05 is nearly the same like the CPU time.
http://numberfields.asu.edu/NumberFields/result.php?resultid=11110368
but on 3.04 the runtime is twice of the CPU time
http://numberfields.asu.edu/NumberFields/result.php?resultid=11143093
For me it looks like, the faster algorithm i not really faster related to the runtime.

looks like there is an issue on the "Get Decics with Bounded Discriminant v3.03"
on one of my computers only one result finish OK,
here is the good one
http://numberfields.asu.edu/NumberFields/result.php?resultid=11107827

all other end in calculation error with different times
sample result for calculation error
http://numberfields.asu.edu/NumberFields/result.php?resultid=11107958

Host
http://numberfields.asu.edu/NumberFields/results.php?hostid=22930&offset=0&show_names=0&state=0&appid=2

stderr is empty for that results with calculation error.

CPU usage is less 50% for the last result (i've seen) and based on

same on the other host

Hi Eric,
stderr.txt is on the way.

I had 4 results, that like to run "forever"

For me it looks like check pointing does not work correct. But I'm not sure.
Attached the last two starts of the result, running round 8 hours each day.

interesting, package
http://numberfields.asu.edu/NumberFields/workunit.php?wuid=10081686
has a valid result with CPU time less 10000 seconds.
My result hasn't finished after more than 2 days CPU time.
The CPU performance is not so different based on boinc measurement.
This looks strange to me.
And the values in the "GetBoundedDecics_state" file of my result increase every minute.

Today morning I had the following values:
0
-2
30
8
-62
13324144
0
13322140
0
241474

I've two long running results
for both the progress bar does not change since some days, I've recognized it yesterday.
But the results checkpoint round every minute (the files "GetBoundedDecics_state" and "boinc_task_state.xml" are updated every minute)

http://numberfields.asu.edu/NumberFields/workunit.php?wuid=10081686
CPU time now: 26 hours at 38,37% (server deadline 19 Jun 2015, 12:34:13 UTC)

http://numberfields.asu.edu/NumberFields/workunit.php?wuid=10094998
CPU time now: 19 hours at 35,95% (server deadline 21 Jun 2015, 9:58:28 UTC)

can you extend the deadline on Server for my results, so no one else gets this results?
Or should I abort this results on my host?

Hi Eric,
can you extend the deadline for this result?
It's running since 3 Days, and now at 79%. I have to shut down the machine for 3 Days during a power outage over the weekend.
http://numberfields.asu.edu/NumberFields/result.php?resultid=887424
Regular deadline is 24 Mar 2012 | 2:21:10 UTC
Time to go 19 hours.
Thanks.
