I have installed 10.3 from 10.2 with a restart of the system on win7 64bit ultimate without any issues.

Longer WUs or larger cache. My ATI 5850 has only a 18h cache max bad for server timeouts, so the database need to be small longer WUs are required.


Setting the cache to 1 day gets the maximum WUs numbers of 150 downloaded to the cache for my HD5850.

Perhaps you need a larger cache request?


Yes.

I'm trying to figure out the format of the job_log_[project_url].txt file that is located in the boinc data folder.

For example, here's a line from a PrimeGrid result:

1265735957 ue 1100.352164 ct 1793.368700 fe 1723560682797 nm pps_llr_extended_43432726_2 et 2034.575577


I assume the first number is the date/time followed by
ue = ????? estimate
ct = cpu time
fe = flops estimate
nm = name
et = elapsed time (a.k.a run time)

So... anyone know what "ue" stands for?


Could be "unit estimated". But Iam not sure.

The code for v1.10 doesn't run 100% on the CUDA device. It calculates the steps for a grid of numbers on the CUDA device, but the sum and max of the steps is being done on the CPU. The plan is for v2.00 to do all calculations on the GPU which should put a lot more stress on the GPU.


Yes, I see, I run now 3+1 and the time is 1/2 for a WU.

It is not the power, it is the time slicing to access the CPU component for the WU. Hence what Logan was saying. Depending on what projects you are running alongside it.



I have the same constellation as in 32bit XP but in all GPU projects the performance is not acceptable.

Uhmmmm... Are you running other projects in that machine...?

Some projects can slow down your card performance... I'm using a GTX260 (OCed) in a Q6600 (XP32)... 770 seconds per WU, but if I crunch AQUA or Milkyway in the CPU, the wallclock time is increased...


Only 4 tasks on WCG too but this project need less power.

I checked some hosts and a GTX260 need around 600-800s to finished one WU, My time on every WU is around 1800s on the same card on Win7 Ultimate 64bit, running now with 6.6.37, before 6.10.4 without any improvement, driver is the newest 190.xx. The gpu is at 67°C with 40% fanspeed (very low) so the card has not the full performance.

Any hints?

Speedup on 32bit Windows with GTX260 around 57% :)

old: 14min
new: 8min

Error:

After the suspension of GPUGRID first WU of collatz crash, second is crunching normally.

This bad WUs
WU
WU

BOINC 6.6.28, driver 182.50, XPSP3 32bit.


You need to update BOINC version to 6.6.36, better .37, the old one had a bug where another GPU WU ist starting...
