Hi Patrick.
Hey Shaun,
Good to 'see' you mate.
Astropulse WUs are prefixed by "ap_", have lots longer file names
and have run times listed that are approximately 5 x that of
'normal' WUs. Also, under the "Application" column in Task Manager
it shows Astropulse 3.45 instead of SETI@home Enhanced 5.27.
(Astroplulse 3.45.exe is downloaded when you get the first
Astropulse WU.)
Aha, haven't spotted anything like that, even on machines which are
clearly capable of processing these WUs.
It seems that they've only been rolled out in the last couple weeks.
From: http://setiathome.berkeley.edu/ap_faq.php
"If you are using an optimised application then you will need to
replace or modify the app_info.xml file.
An app_info.xml file will be made available here."
However, I don't think that the file is there yet. I don't see a
link to it.
Nope, I don't see anything either. Also nothing from the site I
downloaded these optimized binaries from (the 'lunatics' site from
the third-party list).
I didn't realise how new Astropulse is, seems I came back to SETI just as
they introduced it.
I set my BOINC directory to my programmes partition and the data
directory to my data drive. I liked having the option, it means my
programmes partition doesn't get too fragmented over time with BOINC
constantly writing/deleting data.
I have programs and data mixed. ;)
I'm a neat freak. (I prefer 'optimised' really.) I have multiple HDDs in my
main machine so like to split I/O between disks but even in my PCs that have
a single disk I have seperate partitions for OS, programmes and data. I find
that systems run faster like that and it's easier to keep fragmentation to a
minimum.
Hard to know for sure, I installed 6.2.12 after not running BOINC
for a while. However, I seem to remember seeing a couple of
long-expired WUs in BOINC task manager when I started it so maybe it
moved them. If I were you I'd set my preferences to 0 / 0 days a
while before you install it, just in case. Even worst case scenario
is only losing the WUs that the client is currently working on as
downloaded but unprocessed units haven't actually cost you any CPU
time..
I'll probably backup the directory, and just try it on one of my
slower Windows-based machines to see what happens. I must say I find
this change in the installer a bit confusing at best; a notice about
the current location of the data, and perhaps explicitly having it
mention that data will or will not be moved, would've been nice...
It seems that Tazz has experience with this so it might be a good idea to
flush your cache first. Perhaps now? While the servers are down your cache
might be empty? I'm just glad that I have a couple Astropulse WUs queued
(last one processing now) so that I had work during this server outage. In a
couple hours my cores are going to go into rest mode.
Cheers,
