When AP runs MB doesn't. So, I would expect that 2 AP's could run at the same time when MB isn't doing anything.

With your app_config settings, that seems odd. Are you sure BOINC is actually reading the app_config.xml file? When you start BOINC, or if you select "Read config files" on the Advanced menu, does your Event Log show a "Found app_config.xml" entry?


I got BOINC to finally re-read the app_config.xml. It is now crunching 2 AP WU's at a time. I will monitor for any problems.

Thanks everyone. :-)

You didn't mention whether, when a single AP task is running on your gpu, an MB task is also running. Based on your app_config.xml, I'd expect that to be the case.

I've found that BOINC is sometimes unpredictable when a host is running mixed AP and MB, and the <gpu_usage> values are different for the two types. On my T7400, which currently has a GTX 780, a GTX 670, and a GTX 660, I've tried to set up the app_config.xml to run either 3 MB tasks on each GPU, or 1 AP and 2 MB tasks, which I've found makes about the most efficient use of those GPUs.

Theoretically, <gpu_usage> of .34 for the AP and .33 for the MB should do that, and it does.....most of the time. When an AP comes to the top of the queue, it will start up when an MB finishes, if there isn't already an AP running on that GPU. Once all 3 GPUs have a single AP running, BOINC will usually bypass APs and replace an MB that finishes with the next MB in line. However, sometimes it doesn't do that. In those cases, when an MB finishes on a GPU that already has an AP running, it won't start the next MB but will instead wait until the last MB finishes and then launch a second AP on that GPU, which makes that GPU noticeably underutilized.

So, sometimes I just set both AP and MB <gpu_usage> values to .33 and take my chances that I won't wind up with 3 APs running at the same time on one GPU. That's usually not a problem when APs are scattered in the queue, as is usually the case, but every once in a while the scheduler sends a whole block of APs at once, or on consecutive work fetches.

In any event, with your settings, you might not be able to get 2 APs running at the same time unless the 2nd and 3rd MBs finish at exactly the same time, or if BOINC decides to wait for all MBs to finish in order to launch the 2nd AP.

EDIT: Actually, the more I think about it, the more it seems the difficulty might be in launching the first AP, since when a single MB finishes, it only frees up .33 of a GPU, while the AP needs .5 GPU to start. BOINC would have to wait for a second MB to finish before it could launch the AP.


When AP runs MB doesn't. So, I would expect that 2 AP's could run at the same time when MB isn't doing anything.

Seems to me that the <max_concurrent> lines might be your problem. If I recall, that limits the total number of tasks that the application (i.e., astropulse_v7, astropulse_v6, setiathome_v7) can run on your machine, not the total number for a given GPU. You should probably remove those lines.


Jeff,

I got the <max_current> lines from Joe Segur when I asked about creating an app_config.xml for Beta. The changes I made to the app_config.xml for MB for Main and Beta work flawlessly. They should also work, then, for AP - shouldn't they???


TL

Yeah, I guess if you only have the one GPU and you're not running any APs on your CPU, it shouldn't make any difference.


Yes, I'm only crunching GPU, no CPU is used; except to feed the GPU. :-)

I believe for each task you run you need to have one CPU core free. Of course I am only talking about tasks related to this thread


I have a dual core CPU. One core feeds the GPU the other does nothing, I don't crunch on CPU at all; so, one core is ALWAYS free.

50 years ago the fireplace was always considered the focal point in a room, and furniture was arranged to face it. But you couldn't move a fireplace! Modern flats and houses these days tend not to have fireplaces any more, so the TV has become the focal point, which is easier to move.


My dad did!!! We tore down the fireplace from the Southeast corner and built a new one on the East wall during our 1996 remodel. To me, that's moving a fireplace. ;-) :-)

Also, where did you put those app_config files?



For SETI Main:

C:\Documents and Settings\All Users\Application Data\BOINC\projects\setiathome.berkeley.edu


For SETI Beta:

C:\Documents and Settings\All Users\Application Data\BOINC\projects\setiweb.ssl.berkeley.edu_beta


They work fine for MB; I flawlessly get 3 Wu's crunching at a time for SETI Main and Beta. I just want to get them working for AP as well.

Still, SETI and Beta show that they will only crunch 1 at a time.

Please confirm that you mean that Seti and Seti Beta are both crunching one Wu at a time, at the same time,

Or that Seti Or Seti Beta Crunches one Wu at a time, ie one or the other.

Claggy


Claggy,

My SETI Main for MB crunches 3 WU's at a time; as set by my app_config.xml. I wanted to set my app_config.xml to also crunch 2 AP WU's at a time - be they AP 6 or AP 7. (See app_config.xml in last post.) I thought I set the app_config.xml correctly to achieve this goal.

OK; with the release of AP 7, I upgraded Lunatics from 0.41 to 0.43. I suspended all projects, and exited BOINC to make changes to app_config.xml. Modified app_config.xml to allow 2 AP 6 and 7 WU's to crunch at a time on my NVIDIA GTX760. Then, restarted BOINC, and resumed all projects, and hit Update on SETI and Beta.

Still, SETI and Beta show that they will only crunch 1 at a time. WHY??? How long does it take for the change in app_config.xml to take effect???

app_config.xml - (SETI Main)

<app_config>

Have I done something wrong? Or, does it just take awhile for BOINC to update what the app_config.xml says should be crunched???


Thanks everyone.

Yes, I've been looking at it for a couple of hours, now. I have special glasses for the occasion. :-)
