Thanks for the clarification on this VW - will keep this as plan B

Im going to work with richard to see if we can get re-scheduler working with fermi so that we can come up with a process for doing this as I know Im not the only one who needs it working as the normal scheduler does not work that well for fermi yet..

I have shutdown BOINC, used rescheduler to move 6 tasks across,but I having trouble locating the 6 tasks I have moved in the client state.xml file.
What field am I looking for?
I can see 4 active tasks, lots of results, and Im guessing that I want to look at the workunit field and version number?

I can see an app version filed which gives the relevant info on the filename

ile_name>setiathome_6.10_windows_intelx86__cuda_fermi.exe</file_name>

Then a section below which is a mirror of my app info...

Then I get to the workunit section - sample below

<workunit>
<name>05no09ag.3059.6207.13.10.168</name>
<app_name>setiathome_enhanced</app_name> Im guessing that this is where the error is
<version_num>610</version_num>
<rsc_fpops_est>157714230303466.000000</rsc_fpops_est>
<rsc_fpops_bound>1577142303034660.000000</rsc_fpops_bound>
<rsc_memory_bound>33554432.000000</rsc_memory_bound>
<rsc_disk_bound>33554432.000000</rsc_disk_bound>
<file_ref>
<file_name>05no09ag.3059.6207.13.10.168</file_name>
<open_name>work_unit.sah</open_name>
</file_ref>
</workunit>

Then I get down to the result field

<result>
<name>05no09ag.19879.25021.12.10.248_0</name>
<final_cpu_time>0.000000</final_cpu_time>
<final_elapsed_time>0.000000</final_elapsed_time>
<exit_status>0</exit_status>
<state>2</state>
<platform>windows_intelx86</platform>
<version_num>610</version_num>
<plan_class>cuda</plan_class>
<wu_name>05no09ag.19879.25021.12.10.248</wu_name>
<report_deadline>1280546919.000000</report_deadline>
<received_time>1276603771.589111</received_time>
<file_ref>
<file_name>05no09ag.19879.25021.12.10.248_0_0</file_name>
<open_name>result.sah</open_name>
</file_ref>
</result>

Thats all I can find..

Any help anyone on anything else I should be looking for.....

Message 1004575 - Posted: 16 Jun 2010, 8:45:43 UTC - in response to Message 1004474.  

I was just in the middle of typing an answer to this when maintenance hit, 30 minutes before I was expecting it. They were in a hurry to get started! (And I was never so relieved to see maintenance start - went straight out for a long walk in the sunshine. I needed that!)

Now I just redid this app_info, As I used My normal app_info as a template, The only lines that are important to alter are as follows:

<name>MissPiggy_608.exe</name>
<version_num>6085</version_num>
<file_name>MissPiggy_6085.exe</file_name>

After all You do want It to run, The PC doesn't care what You name It one bit, As It could be named Cookie Monster and the PC would accept It.

This is on the PC end, I don't know if the Server end has a fixed set of names that It recognizes or not, If It does then don't do this.

That's absolutely right - the name doesn't matter. But I'd still strongly urge people not to rename MissPiggy_608.exe to KermitTheFrog_610.exe - that would cause endless confusion for us (and them!) if you/they ever need help/counselling....

I was going on to talk about the significance of <plan_class>, but I see MadMaC's post answers my next question, so I'll move on to that one.

MadMaC,

<app_name>setiathome_enhanced</app_name> Im guessing that this is where the error is
No, this string of <workunit> section is correct. It's multibeam workunit.

<version_num>610</version_num>
<plan_class>cuda</plan_class>
Here for fermi-oriented app 6.10 must be

<plan_class>cuda_fermi</plan_class>

Rescheduler 1.9 doesn't know about new version 6.10 and this new plan_class - at compilation time such new things didn't exists...

No, that's not it - leave that one well alone. Eevery current workunit will be either "setiathome_enhanced" or "astropulse_v505" - no other choice.

The problem is actually in the "result" section:

<result>
<name>05no09ag.19879.25021.12.10.248_0</name>
<final_cpu_time>0.000000</final_cpu_time>

<open_name>result.sah</open_name>
</file_ref>
</result>

That's the one I was going to talk to Victor about - the extra important line, apart from <version_num>, involved in re-branding.

You have obviously set up ReScheduler to use version 610 for the re-branded (new) CUDA tasks - which is right. But (so far as I know) Marius hasn't provided any mechanism for modifying the <plan_class>.

One work-round would be to do a global search-and-replace on client_state.xml - or at least the SETI@home part of it (don't change any sections belonging to other projects!). Usual warnings: take backups, have BOINC fully shut down, use Notepad or another plain-text editor only.

The change would be: Replace

<plan_class>cuda</plan_class>

with

<plan_class>cuda_fermi</plan_class>

But I don't recommend it: you would have to repeat the change every time you re-scheduled work from CPU to GPU.

Far better to modify your app_info.

Look back to post #2. Copy the whole first section (<app_version> ... </app_version>) again, and paste it as a whole duplicate section into app_info (keep it inside the <app_info> ... </app_info> tags, but clear of everything else).

Then, in one of the duplicate app_version blocks, change <plan_class>cuda_fermi</plan_class> to <plan_class>cuda</plan_class>. That should give you the necessary tool for processing the results modified by ReScheduler. Let us kow how you get on.

OK - think I have done this right...

The last section is the duplicated one...

Ah - I'd forgotten you'd already modified the file with those <platform> tags for 64-bit Windows.

Look at the app_info you've posted, and try to get used to seeing the 'shape' of the file: separate sections, each with a <tag> ... </tag> enclosing it.

You've now got three <app_version> sections. You can probably get away with that, as the sample (rebranded) <result> you posted had the vital clue:

<platform>windows_intelx86</platform>

I suggest you add that to the new (third) <app_version> block, so it matches the first one. And then check again for any other differences I've missed, before you run it!

Sounding good. I recommend you take it one step at a time. Assuming you're crunching good work (sensible run times), sit back and take a breather. Wait for the servers to come back up, so you can report the work and - crucially - test that you can still download new work.

If that's OK, you can just put back the <flops> correction, and the job's finished.

Sorry for to be offtopic..

I know, the ReSchedule V1.9 tool don't work with SETI@home Beta Test.

But, is there a way to get let it run there also with some mods?
Maybe two instances of ReSchedule tools separately? Different installation paths.
And mods of .xml files?
Yes, maybe lot of handwork, but worth to do it.

I thought maybe you have tested it in past.


Since my account was deleted over at the Lunatics forum, I have no change to get in contact with Marius.

You know his SETI@home account number?

As it happens, I have never even downloaded Marius's program, but I can read the posts about it.

If Marius has time to revise the program, then I am sure the will have time to read here as well, and will see your suggestion.

I use a vbs script which Fred W originally developed, and which I have subsequently tweaked and enhanced to my own satisfaction. Because it's a plain-text file, I have full control over it, and I can customise it to suit changing circumstances - such as the arrival of Fermi.

No, I'm not going to do that, because from my life outside SETI and BOINC, I know that if you develop a tool and supply it to others, you have a duty of care to maintain and support it - and if you don't, people keep pestering you with an expectation that you will.

To me, SETI / BOINC is a hobby and a pleasure. The moment it becomes a duty, the fun goes out of it. I made that mistake once, when I agreed (under pressure) to become a Mod. That experience was so unpleasant I nearly left BOINC altogether: I was coaxed back by friendly emails from other projects, not this one.

I'm not going to make that mistake again.

All tasks for computer 4292666

Automatic download while I was asleep. 32-bit Windows XP, GTX 470, optimised apps + stock v6.10 exe, no platform tag in app_info.

Unfortunately, they're all VLAR like task 1635955802, and my rebranding script didn't pick them up. Where's that support guy when you need him........

........ah, I see. My script works on the distinctive <rsc_fpops_est> signature of VLARs, to save the overhead of opening and reading each actual data file - which means it works during downloading, unlike ReScheduler.

Er, worked. The new server-side DCF adjuster fiddles with <rsc_fpops_est> ...... WAAAAAAARRRGGGHHHH! Berkeley Broke My Script! Support!
