Can't understand CPU/GPU workload - not using 2nd GPU, not multiple GPU tasks, etc.

Hi - Well ever since the OpenCL apps came out my machines (3 of them) are doing all kinds of weird, unexplained things with scheduling/running tasks for einstien@home, and I only get like 1/3 to 1/2 as much credit, it's very very annoying.

I am using BOINC version 7.2.42.

Right now I'd like it to fully use my GPUs, it's NOT happening, nor does it really use all Hyperthreaded cores of the CPU (sometimes, unexplained why).

What is wrong? It's driving me crazy, can't tell what the problem is, so to recap
a) Why doesn't it currently use the 2nd NVIDIA GPU
b) Why do I only get a single GPU task?

Currently it's running 8 GW S6 Directed Search (CasA) 1.05 (SSE2) tasks, and 1 FGRPopencl-nvidia which says (1 CPU + 1 Nvidia GPU (device 0))

I used to get 3 tasks running on a single GPU, and for as many GPUs as I had. And if I have a 4-core CPU, I'd get 8 threads with hyperthreading enabled.
Now I'm lucky if I get 1 task per GPU and 7 CPU tasks (right now it's running 8 on THIS particular computer, not all 3 computers act exactly the same for some reason), and doesn't use all GPUs installed.

So right now my problem is, won't use 2nd GPU at all, and 1st GPU uses only a single task. 1st GPU less than 45% loaded, and almost no memory load.

First - I only use einstein@home, no other apps.
I have a cc_config.xml that looks like (and no other special config files, no app_config.xml, etc.):

From the output below you can see I'm using general prefs and for "home", here's what they're set to in my account:
Resource share
Determines the proportion of your computer's resources allocated to this project. Example: if you participate in two BOINC projects with resource shares of 100 and 200, the first will get 1/3 of your resources and the second will get 2/3. 100

Does your cc_config.xml file have this line in it?

The use all gpus line tells Boinc to use every gpu it sees and is needed on some systems. Other systems need one of these:
http://www.overclock.net/t/384733/the-30-second-dummy-plug

You can get the resistors at a local electronics store for under 2 bucks for 5 of them. The other option would be to plug in a second monitor when the machine boots up as Windows often turns the 2nd gpu off if nothing is plugged into it during the boot up process, it thinks it is saving resources. After the machine is up and running you can unplug the 2nd monitor.

As for why some cpu cores are not running individual units it is probably due to the kinds of units you are running here. SOME Einstein units use BOTH a cpu core AND a gpu to run ONE SINGLE UNIT, so while it may look like nothing is running, in fact it could be being used. BUT be sure to leave one cpu core free for EACH physical gpu you have so the gpu is not waiting on a cpu core to feed it data. A gpu is MUCH faster at crunching then a cpu core is, so keeping the gpu's fed is critical. Check your times both ways and do what works best for your pc.

RE: a) Why doesn't it

You said that you started Boinc without a cc_config.xml. When adding the tag one has to restart Boinc for it to take effect. A simple reread won't do. The detection of GPUs and decisions about what to use is only done at startup and can't be forced again.

Quote:
b) Why do I only get a single GPU task?


Because the default settings and the settings you posted is set to run only 1 GPU task per GPU.

This can be changed in 2 ways, either by editing the Einstein@home prefs and setting the GPU utilization factors to less then one, 0.5 = 2 tasks, 0.33 = 3 tasks. These utilization prefs will not get updated and used until new work for that type of task is downloaded.
The other way to control this is by creating a app_config.xml in the project directory, this allows one to control both how many tasks to run at a given time and the changes take effect as soon as one does a reread of the config files in Boinc.

This is an example app_config.xml that will run 2 GPU tasks at any given time, for the BRP4G and BRP5 tasks it will reserve 1 CPU core for 2 tasks but for the FGRP3 tasks it will reserve 1 CPU core per task.

BRP4G = Binary Radio Pulsar Search (Arecibo, GPU)
BRP5 = Binary Radio Pulsar Search (Perseus Arm Survey)
FGRP3 = Gamma-ray pulsar search #3

[/pre]
If you want to try it then copy everything between and including to into notepad, then save the file as app_config.xml in C:\ProgramData\Boinc\projects\einstein.phys.uwm.edu and make sure it's not called app_config.xml.txt. Then open Boinc and do a reread of the config files and it should work.

You can then edit the to control how many task to run, 1=1, 0.5=2, 0.33=3.
The controls how many CPU cores to reserve, once the fractional values adds up to 1 then one less CPU task will be started by Boinc.

Take not that the FGRP3 app really needs a full CPU core as support because the app only runs some of the computations on the GPU a major part of it still needs to be run on a CPU.

Recently moved over from SETI

Recently moved over from SETI but Einstein is only using 1 gpu and also not hyperthreading the cpu's.  Need an example cc_config.xml for Einstein and some advice on forcing use of hyperthreading the cpu's.  Thanks.

Hi Bill and welcome back to

Hi Bill and welcome back to Einstein!

You've managed to dig up a thread from 2014 and anything discussed in it will probably not be applicable to how things work today.
I encourage you to start a new thread to get help with what you want to achieve.
In that new thread try to give some more info on what you want to achieve.

A quick look at your computers reveals that you have 3 attached, which of these are you having trouble with?

If I understand your goals then you should be able to accomplish most of it without using extra configuration files.

cc_config.xml is not project specific, it's a Core Client Configuration file and adjusts how Boinc on your computer behaves in general.

Only you can see what's actually running on your computer.
Please start a new thread and tell us what you do see running and what you expect or want to see running.
