It's an Intel i7/7700K (4 core / 8 threads) and yes, the machine has been recycled since I started crunching M/W.

Its' been a long tome since I crunched here and I'm wondering if my GTX 1070 is working at its' max. My app_config.xml is

<app_config>
<app>
<name>milkyway</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_versions>
</app>
</app_config>

, but I'm only running 1 task per instead of 2. Any suggestions?

Been away for a while and things have gotten confused when attempting the app_info.xml and I need some help.

02/27/2014 07:46:49 | Milkyway@Home | Syntax error in app_info.xml, but XML Maker 2.2 states there is no syntax error


What program are you using to 'make them'? Since you are using Windows use NOTEPAD ONLY to make the files as word processing progressing programs add hidden stuff that Boinc doesn't like.


The syntax error was caused by the missing tags <app_info> , </app_info>. As far as using XML Maker to create/edit my .XML files, it was suggested by several people at SETI a couple of years ago when I was having problems with syntax.

Hmmm...

Are you using all the CPU cores to run tasks? I found I have to leave one free to drive MW, Collatz, and SAH to max GPU utilization. That gives me 98-99% for MW, and Collatz, and generally better than 95% for SAH (IOW's BOINC restricted to 7 of 8 on the FX-8350).

EAH is a different story. Apparently, it needs far more CPU support for the GPU so I have it spec'ed so when more than 4 want to run it will grab another CPU to help out and even then I can only get to about 85% by running 4 each on my dual 7970's.

<edit> Oh yeah, the MW, Collatz, and SAH data was for running 4 each on the duals, as well.


I'm running BOINC @ 90% (7 cores). Normally I run only S@H AP (both CPU & GPU) on this machine. When the GPU tasks run out, then MW kicks in to fill the GPU gap. Since my earlier post, I've figured out what was needed for the MW app_config.xml file. Right now I running 5 S$H AP CPU tasks, with 2 each MW Separation Modified Fit per GPU, and the GPUs are running at 99%. Whenever I will get some MW OpenCL tasks, they too will run with .5 core reserved for each task and is set up to run 4 tasks per GPU.

Not sure if this is the right thread, but will try anyway. Started working on the MW Separation Modified Fit (OpenCL only) on 2 x GTX660SC @ 2Gb. Each task is currently using .503 core & 1 GPU. The problem is they are using only approx. 69-75% of the GPU. What do I need to have the CPU & GPU set to .5, so that I reserve a half core CPU, and still run multiple (2) tasks per GPU attempting to get 99% usage?

I am also working Milkyway (OpenCL only) using the default app_info.xml, increasing the GPU to 3 tasks in an attempting to reach 99% usage.

8) Message boards : Number crunching : Event Log Flags (Message 57344)
Posted 24 Feb 2013 by Cliff Harding
Post:
Since the main program we crunch under is Boinc, at BOTH Seti and here, the debug flags would be identical.


Ok, I'm running 7.0.52 and thought I had a bug. Never really looked at the complete log when Milkyway is running as I mostly run SETI and concentrate all of my log views on that project. It is very disconcerting not to see any down/up messages in the log to do a spot check on which tasks have been transferred. Case in point, on 23 Feb at the beginning of the SETI outage I d/l'ed some Milkyway tasks. Later to cut down on the failed SETI transfer entries in the log I set the network activity to NNT, forgetting about Milkyway. When I noticed that I was not getting any new tasks from here, I clicked on the SHOW ALL TASKS button and saw a load of tasks waiting to report. I allowed network activity to resume, and that is when I noticed that there were no up/down messages. The only way that I can see that files were in fact sucessfully being transferred was to turn on the TASK DEBUG flag.


When I go into the Boinc Manager, down by the clock, and then Advanced, Event Log I see things like this:
2/24/2013 11:12:39 AM | Milkyway@Home | Scheduler request completed: got 1 new tasks

Could you just be looking in a different place?



All well and good, I have seen the same thing, but what I don't see are specific lines for the transferred files as in the following examples from Einstein & SETI.

Post:
Are you talking about 1 mw over all cores (multithreaded app like mw nbody) or 1 mw per core (makes 6 * mw)?


Sorry 'bout that. I'm talking 6 tasks, 1 per core. It seems that it only applies to MW 1.00. Nbody is not affected in this manner, which appears to have a normal mix of between cores; meaning Nbody will not overtake more than its resource share.

Post:
Currently running both SETI (100%) and Milkyway (50%) on my i7/950 machine, running on 6 of 8 cores. I have noticed that when Milkyway 1.00 tasks are running they are running on all available cores, placing the SETI tasks in 'waiting to run' state. Is this normal? I was expecting to see a mix of both SETI & Milkyway tasks executing at the same time. Deadline for the Milkyway tasks is far enough away to see this happening.

It should be noted that the machine is running BOINC 7.0.15 and there might be a scheduler problem, but this situation has been in existance even in the 6.10 & 6.12 versions.

Post:
Thanks again arkayn, your opencl app and app_info are working great so far. I just hope it wasn't a mistake upgrading to Boinc 7.


What version were you using prior to the upgrade? I was using 6.12.34 prior to ugrading to 7.0.8 -> 7.0.15 on my A-SYS without any problems except that one of my devices EVGA GTS250 was not double precision compatible and the WUs were aborting. With the exclude_gpu option in the cc_config.xml file for that device I was able to prevent it for getting opencl work. This option will work for your situation as well.

Posted 27 Sep 2010 by Cliff Harding
Post:
I have a very unique card EVGA GTX275 w/ integrated GTS250. This is a card that has two separate physical double precision capable processors on the same card. Normally the GTS250 (GPU1) will not support double precision if on a card by itself. But in this instance because it is intregrated with the GTX275 (GPU0) it is. You may want to add this card to your list for those who have this type of card but have not designated the GTS250 to crunch GPU WUs.

Normally, I only crunch SETI, but I was doing a test by downloading some MW tasks for timing purposes. I noticed that all of the downloaded tasks were GPUs and when they started crunching is when I discovered that both GPUs were crunching on MW; instead of one on MW and the other on SETI.

I am currently running two projects on two machines (Windows 7 & Vista Business) using the current BOINC software (6.10.18). In this version I have noticed not only do I get the active SETI screen saver, but also static displays of all tasks that are currently running; which includes Milkyway.

I know it is very little to go on right now, but at least it gives me a reminder of what is currently running. If you have Windows and you haven't upgraded, now might be a good idea.
