Looks like the simplest calculation of the number of cores in a Quad CPU is a hard work. After starting the 6.3.14 only 3 tasks are running. So I had to create a new cc_config.xml to tell the program the real number of cores in my CPU. After the Entry ncpus=4 the program is running fine.

Second comment to the 6.3.14:

Finally the 6.3.14 don't eat memory when the BOINC-Manager is running under Vista 64 bit :)

Please change the entry

Aktiv (1.00 CPUs, 1 CUDA) to Aktiv (1.00 Cores, 1 CUDA)

I think, you mean to control the feeding of the GPU is one core needed and not the whole CPU wirh all 4 cores ;)

Question:
Is the number of 2 cores hard coded in this version? I'm wondering, while 2 CPU tasks und one GPU tasks are running on a Quad if no ncpus-entry is available with the real number of cores in Windows.

A team mate told me, on Linux the right number of tasks is started. I will ask back for a cc_config.xml.

EDIT: He has running a cc_config.xml with ncpus=5, so I think, the Linux-Version has the same problem.

I've been running x2 hosts for about 3-4 hours. I just installed on 3rd host a few minutes ago. All are Windows XP x86

I did not want to post immediately until some testing had been done. However I have not had any problem so far and been in contact with the developer (Anderson) all day about it. I observed proper task switching when a CPU task ended another was started, so I was always left with max running tasks.

The problem with reading the XML preferences file has been fixed and the proper venue is now used. XML is parsed correctly again.

It seems to be good so far, It starts the proper number of tasks on initial start up, in my case without using ncpus setting I should have 2 and thats what I got. I did not have to do any suspending or other tinkering to get it to work. 1 CPU only and 1 CPU/CUDA task. You will note immediately CUDA tasks show as "Running (1.00 CPUs, 1 CUDA)". CPU only tasks just show as "Running". This amount of CPU used can be set by the project, currently 1.00.

The behavior is suppose to be:

The intended behavior (which I think we've finally achieved)
is that the client runs tasks until all the GPUs and all the CPUs
are utilized.

E.g. if it has a (1 GPU + .75 CPU) job and several 1 CPU jobs,
and your machine has 1 GPU and 2 CPUs,
it will run the GPU job and 2 of the 1-CPU jobs
(so that CPU usage is 2.75, i.e. there will be contention
for the CPUs, but that's better than leaving one of them .25 idle).

BTW, I changed things so that if a job uses a GPU and < 1 CPU,
it gets run at normal process priority.
Hence in this case the GPU job will get .75 CPU
(so that the GPU runs at full speed)
and the two CPU jobs will share the remaining 1.25 CPU.

I've installed the 6.3.14 on a second PC, also on Vista 64 bit. There are 4 tasks running. This PC has a 8800GT. Don't know, why the other only 3 tasks has running without a cc_config.xml at the first start.

I've deleted the entry in the cc_config of the other PC with the GTX280 and after the restart now also 4 tasks are running. The CPU is set to 100% on both PCs.
____________

No linux version of 6.3.14 has been made yet. There hasn't been a linux version made since 6.3.10.

Another remark to the 6.3.14:

The temperature of my GTX280 is dropped from 79°C to 72°C. In the past this only happens with ncpus=5 and a longer running time per WU. I'm really agog for the new time per step, the last with the 6.3.10 was 34.438 ms.

____________

You will note immediately CUDA tasks show as "Running (1.00 CPUs, 1 CUDA)". CPU only tasks just show as "Running". This amount of CPU used can be set by the project, currently 1.00.

The first WU only running under 6.3.14 is ready:

http://www.gpugrid.net/result.php?resultid=75290

# Time per step: 35.483 ms
# Approximate elapsed time for entire WU: 30160.337 s

Looks good!

...... where can I get 6.3.14?

Thanks!

...... where can I get 6.3.14?

This is as before, isn't it?

gdf

.....Got it - thanks.

My first result crunched with 6.3.14 is uploaded - http://www.ps3grid.net/result.php?resultid=75292

It took about 43.6ms/step which is about the same speed than with previous BOINC versions (was always between 43 -45 ms/step).

Worked like a charm, 4 tasks, 3 cpu and 1 gpu.

Did the cc_config.xml to 5 cpus and now its 4 cpu, 1 gpu.

Will have to wait a day or two to average the performance.

I installed the new 6.3.14 this morning and it immediately Trashed the 4 PS3 Wu on the Computer and has Trashed every one since then. Going back to 6.3.10 hasn't helped either as it now Trashes any PS3 Wu I download ... All I get is Computation Errors with the following message:

<core_client_version>6.3.10</core_client_version>

...did install v6.3.14 yesterday - everything is running fine ... :-) speed is the same (as I supposed). On a 32 bit Windows XP prof. SP 3

nice job!

so far I haven't seen any issues with 64bit 6.3.14 on server 2008 x64

out of memory

Did you reboot your machine?

MrS

I managed to get 2 more Wu's again & 1 of them seems to be running ok now after re-booting this morning. I also increased the Page file on the System to see if that helps.

I'd like to try 6.3.14 again, should I un-install the 6.3.10 first or doesn't it matter ... ??? Yesterday I just installed the 6.3.14 over the 6.3.10 & maybe thats where it got screwed up, don't know for sure though ...

Okay, thanks Keith, I'll try it tommorrow, want to let it run over night to make sure there are no other problems before Up-Grading to 6.3.14 again.

Anybody tried multi-gpu on 6.3.14 yet? I'm having issues on my 2x GPU rig. It runs F@H GPU2 fine. My other 2 rigs are single GPU and I'm using the cc_config file and not having any issues.

On the multi-GPU rig:

Vista x64
2x XFX 8800GS

Same effect whether I use the cc_config file or not. I start Boinc (I run WCG and GpuGrid) and it will start running 4 of the WCG WUs and 2 of the GpuGrid WUs, but after a few minutes....sometimes 10-15mins....it will kick both of the GpuGrid WUs into "Waiting to run" mode. The 4 WCG WUs will continue on...and it will not start any other WUs to replace the GpuGrid WUs. For some reason its kicking them out. This doesn't happen on either of my single GPU rigs. And as state before: this is with or w/o the cc_config file, and it doesn't seem to matter what the ncpus is set to when the file is used. Yes, I rebooted. Desktop is extended via vga-dvi dummy. I tried them OCed and at stock.

Driver should be 177.92

All 3 rigs are running Vista x64.

Kinda lost atm...just wondering if anyone else has tried multi-gpu with this version.....?

Ok, I am going to tinker with it tomorrow...headed to bed in a few minutes. But first a question:

How do I set/change the resource share? Is that the "On multiprocessor systems, use at most" which is defaulted to 100%? If not, then I'm lost.

On the projects tab it shows 50% resource share for each project.

The "Resource share and graphics -- PS3GRID preferences" settings in your Account is where you set your Resource Share for each Project.

Ok, found it--Thanx! I don't want to derail this thread too much...if necessary I'll start a new thread:

All 3 of my rigs are set under the "default" profile in Boinc/WCG/and, I guess, GpuGrid. The 2 1xGPU rigs are running fine, so I really don't want to mess with them. Don't really want to put the PCs in different profiles and not sure what headaches might arise from that. Is there a way to change the resource share on just the 1 2xGPU rig?


Just wanted to add that, other than this single issue with the multi-gpu, this 6.3.14 seems like a much better version than .11, .12, .13......

Yes let's start a new thread for this as it pertains to all boinc versions and projects, not just this one.
