I'd posted a sample app_info.xml over there.

This is wonderful!

Thanks Radim & HA-SOFT!

I see very low CPU usage & high GPU load. Perfect!

@tom:

According to CPU World Pentium G2030, your CPU is an IvyBridge.

TDP of 55W don't generate much heat. 30-65c is fine.

I have released the optimized versions for OS X, which were compiled by Crunch3r.


Just allowed new work on my Mac and it downloaded a bunch of v100 tasks which I aborted.

So I reset the project which then downloaded some SSE2 tasks and more v100 tasks, which I aborted.

I don't really want to monitor the downloads all the time - can you do something like allow selection of the optimized app in preferences or maybe even remove the v100?

Thanks!



Steve,

Use the app_info.xml method (I did).

0] BOINC data folder is in /Library/Application Support/BOINC Data

1] download SSE2/SSE3/AVX apps from http://asteroidsathome.net/boinc/download/

2] mv all apps into BOINC Data/projects/asteroidsathome.net_boinc

3] make all apps executable, e.g. chmod +x

4] TextEdit/nano a new app_info.xml as shown below

<app_info>
<app>
<name>period_search</name>
<user_friendly_name>Asteroids</user_friendly_name>
</app>

<!-- SSE2 -->
<file_info>
<name>period_search_10210_x86_64-apple-darwin__sse2</name>
<executable/>
</file_info>
<app_version>
<app_name>period_search</app_name>
<version_num>1021</version_num>
<avg_ncpus>1.00</avg_ncpus>
<max_ncpus>1.00</max_ncpus>
<plan_class>sse2</plan_class>
<file_ref>
<file_name>period_search_10210_x86_64-apple-darwin__sse2</file_name>
<main_program/>
</file_ref>
</app_version>


<!-- SSE3 -->
<file_info>
<name>period_search_10210_x86_64-apple-darwin__sse3</name>
<executable/>
</file_info>
<app_version>
<app_name>period_search</app_name>
<version_num>1021</version_num>
<avg_ncpus>1.00</avg_ncpus>
<max_ncpus>1.00</max_ncpus>
<plan_class>sse3</plan_class>
<file_ref>
<file_name>period_search_10210_x86_64-apple-darwin__sse3</file_name>
<main_program/>
</file_ref>
</app_version>


<!-- AVX -->
<file_info>
<name>period_search_10210_x86_64-apple-darwin__avx</name>
<executable/>
</file_info>
<app_version>
<app_name>period_search</app_name>
<version_num>1021</version_num>
<avg_ncpus>1.00</avg_ncpus>
<max_ncpus>1.00</max_ncpus>
<plan_class>avx</plan_class>
<file_ref>
<file_name>period_search_10210_x86_64-apple-darwin__avx</file_name>
<main_program/>
</file_ref>
</app_version>

</app_info>


(You can remove parts for AVX/SSE3 if you prefer to run SSE2-only)

5] change ownership of all apps & app_info.xml to boinc_master:boinc_project, e.g. chown

6] shutdown & restart BOINC

Good luck.


EDIT:
Save the app_info.xml into BOINC Data/projects/asteroidsathome.net_boinc

Best to
cd /Library/Application Support/BOINC Data/projects/asteroidsathome.net_boinc
and work from there

i7-4770k 4.1GHz x7 WU (1 free thread to feed my GPU)
~1260secs
86400/1260secs= 68.57*7wu = 479.99*120cr = 57598.8 credit per day

My friends, please beware AVX code on Hotwell = increased VID = more heat.
Mine is pulling 1.277V for 4.1GHz and temps shot up +10c (yeah, I'm lazy to optimize... :) ).

When your CPU gets too hot, thermal throttling will happen = lower performance.

If you have good CPU cooling, AVX shaves off a few mins (~3-4mins, x6 WU).

If not, it's best to run sse2/sse3 only.

As there is no way to control which version of the app gets sent to you, you can modify the following app_info.xml by removing AVX plan and stick it in your
BOINC-DATA/projects/asteroidsathome.net_boinc
folder

<app_info>

Happy crunching!


EDIT: Maybe Radim can possibly offer an option in Preferences page? "Enable AVX computing", perhaps?

Message boards : Number crunching : Validator not working?

(Can't edit the above)

Upon further investigation, it looks like invalids are really happening in series.

WU 6284548, 6284568, 6284669 (6284xxx series)
I check other WU within 6284548-6284669, lots of invalids, e.g.
http://asteroidsathome.net/boinc/workunit.php?wuid=6284566
Too many errors (may have bug)
http://asteroidsathome.net/boinc/workunit.php?wuid=6284561
Multiple invalid

But also Valid WUs, e.g.
http://asteroidsathome.net/boinc/workunit.php?wuid=6284567

The worst batch is 6407337 to 6407536 (6407xxx series, created 2013-Sep-10, ~14:49 UTC). I'm afraid that particular batch should be removed.

I just uploaded a huge load of completed WUs, ~1220.

Host 50432 - 2x invalids

Host 48191 - 7x invalids

Host 50012 - 123x invalids

I get WUs in single batch (then turn network off) and it looks like the last host batch contains lots of problematic WUs.

Most Invalids previously processed by other hosts and marked as invalid multiple time.

I think all these hosts (with processed valid WUs) are not at fault.

Something must be very wrong with the WUs, Batch, Output, App, the Validator or...



Project should look into these invalids WUs and ascertain they are not faulty or lead to faulty results.

Otherwise, all efforts are for not, wasteful and project product/results may cause confidence issues.

I love Asteroids@Home - let's kick these gremlins out.
