I get 30% more cobblestones for AP GPU WU for the same power consumption as opposed to MB.

The worse thing about this is not a few abort MB WU when AP WU are back.

It it not a GPU vs. CPU situation but a AP vs. MB WU situation. One does not have to accept any CPU work. If I could get all AP the CPU, 100%, would go to helping the GPUs.

You can quickly fix it by adding a FLOPS entry into the app_info file. You must be careful though, too high a value will result in too short an estimated runtime. This will cause any work in progress to exit with a time exceeded error. An approximate value would be around 40000000000, you would enter it as such;
<app_version>
<app_name>astropulse_v6</app_name>
<version_num>602</version_num>
<flops>40000000000</flops>
<file_ref>
<file_name>ap_6.02r561_OSX64</file_name>
<main_program/>
It would probably be a good idea to remove one of the zeros on the first attempt if you have any work in progress.
You might want to fine tune the number based on what is displayed in the Remaining (estimated) column after restart. A higher number will give a lower estimated time.

I got tried of waiting for the system to level this out so I put in 4 billion on the FLOPS estimate and all tasks that were still in my cache went up to 165 hours from 161. All new arrivals are being estimated at 11 hours as it should be

The above example is showing 40 billion and my floating point speed on my 1100T
Boinc tells me my floating point speed is estimated at 3054.12 million ops/sec so I put in 4000000000

I hope my cache fills up before they shut down the splitters for AP for the week

OP, 600 cobblestones credit for 2 seconds work; I would stick with it.

Yep, credit new works perfect.

Yes a perfect random number generator...

Says 45.34 GFLOPS here, http://setiathome.berkeley.edu/host_app_versions.php?hostid=6339101
The other day when I made that first post I believe it was around 44 and I gave a setting for 40. Then mentioned Fine Tuning....

It's too late to change it now if you have some tasks estimated at 11 hours and some at 165 hours.

The other day when I made that first post I believe it was around 44.

I know my APR is 45 gflops but my bench test for this cpu is 3054.12 million ops/sec
So that is 4 billion.

It's very confusing that is for sure.

I put the extra 0 in to make it 45 billion so we what the estimates show
At 4 billion the estimate was dead on at 11 hours which is the time it takes in reality.
I will keep on it.
Question: After I get enough valid tasks in do I then remove the flops entry?

Thanks very much TBar

If you have some tasks with large differences in estimated times I would leave it alone for now. After all the tasks have close to the same estimated times you can remove it if you wish and see what happens.

So far cache is full.
96 601 units in the cache.


Thanks for the help TBar and all who replied
