Message 43164 - Posted: 25 Oct 2010, 20:25:46 UTC

Im also wondering if i should run MW on my i7 68 hours for a work unit to complete and only getting 213 for credit stinks. And I have more of them to crunch. NNT for me.

The mac is doing them in 9 hours. why so slow on a i7 quad? the same DE- separation units.

Currently I wouldn't let run stock 0.4 app of/for Windows.
AFAIK, the Windows app is little bit buggy. ~ 200 % slower than the Linux app.
The 0.4 app should be ~ 30 % faster than the 0.19, but currently it isn't.
So we need to wait to 0.41 - or what ever which number.

The 0.21 (sse2) nbody app is running well. ~ 45 - 60 mins / WU on my E7600 @ 3.06 GHz.

I just gave MW another chance, however it downloaded a WU that estimated 78 hours running on a 4CPU Mac, where it elevated itself to high priority and grabbed 3.9CPUs. I immediately aborted it and will give MW a 1-2 week vacation. Maybe it will be better later.

The N-body time estimates are almost meaningless; they are really high to avoid BOINC killing off the processes, and an actually good time estimate is hard to make. The number of processors the N-body uses is however many BOINC tells it to use.

That's what I thought, but MW still locks out all other Projects!

There are 5 projects and all have Resource share set to 100. There are 4 CPUs so there should be 4 tasks running at one time. MW shows a Status of Running, high priority (3.90 CPUs) and the other tasks are Waiting to run.

Boinc Processor usage preferences are set to

On multiprocessors, use at most 4 processors
On multiprocessors, use at most 100 % of the processors
Use at most 100 percent of CPU time

How can I force MW to not lock out the other tasks?

Ski King, it can takes weeks for BOINC to even out the work history of all projects when you add a new project. In effect, BOINC is looking at the long term average CPU useage of all your projects, and trying to even them out. If you just added MW, its long term average is very low, and probably much lower than the projects you have been running. Right now, BOINC is using all your CPUs on MW, so its average goes up some every day, while the long term averages of the other projects goes down some every day. Once the averages are roughly equal, BOINC will start sharing the CPUs between all the projects.

From my observations of BOINC 6.10.56/58, it's not at all clear that the BOINC scheduler is working as you might expect. It's had over a year to balance the workload between 5 CPU projects on my machines here. Once the MW 0.04/0.40 WU run times headed for the moon, it did not throttle back MW WU counts on the machines. Instead, as I write this, it has 15-17 WU's downloaded for MW on each machine (to satisfy only a 1-day cache) with each of these estimated at 31-35 hours run time. Each machine only has 16 (hyperthreaded) cores available.

With 7-day turnaround time required, it's now running up to 6 of these MW WU's per machine at high priority. With MW version 0.19, it never ran any at high priority.

Still getting errors on my G4 Macs; a small mercy is that the tasks bomb right away, so the time-wastage is negligible. Have set the project to NNT on all three until a new app becomes available.

Well I still don't see anything that states this problem is resolved so I will remain NNT on Milkywave until I see something positive.

This problem was fixed a long time ago now. I think the only problem mentioned here that's probably still the case is the failures on some old OS X PPC systems.

The pb I am experiencing sonce a couple of days:
I am getting MW WUs by the dozens but all of them claim to be finished within 2 seconds, uploading and then they are invalid. The problem is that MW keeps sending those WUs and I ran completely out of "real" WUs.

That isn't the stock application. That doesn't look like it's going to work.
