Switched over to do some Proth Prime Search (Sieve) PPS (Sieve) 1.39 to boost up to silver badge as the challenge WU's currently shrubbing complete.

Having done PPS (Sieve) WU's previously, have already reached Bronze with 164K + credits. Average credit per WU was 2311.

Under preferences it advises the tasks should take: Recent average CPU time: 2:10:17

Pretty sure my PC will be capable of doing to within a 10% +/- margin.

WU's downloaded said they would take 133.??? hours.

While waiting for the first WU to commence the time dropped to 109:??? hours.

First WU in progress jumped up to 199:??? hours to completion with a slow drop down.

Been running the first WU for just shy of 1 hour and by the time I have written this message it will be over an hour. Current time to completion is now at 132:??? hours.

Questions
1. Is this a BONIC timing error?
2. If so what is the realistic time to completion?
3. Assuming this is not an error what credit can I expect?

PPS sieve is mostly crunched with GPU's (both ATI and Nvidia). Average cpu times on gpu crunchable tasks (PPS sieve, CW sieve and GFN) are not a good indicator of real crunching time. I have not run PPS sieve with cpu for ages, but > 100 hours would not surprise me.

Taken from the current preferences page
Proth Prime Search (Sieve)
Supported platforms:
Windows: 32bit, 64bit (+CUDA23, AMD OpenCL1)
Linux: 32bit, 64bit (+CUDA23, AMD OpenCL1)
Mac: 32bit, 64bit (+CUDA32, AMD OpenCL1 - 64 bit only)
1 Requires AMD Accelerated Parallel Processing (APP) drivers.If APP driver not available for your card, then the ATI Stream SDK is needed.
Nvidia Windows drivers 295.xx and 296.xx should not be used.

Recent average CPU time: 2:10:17


In this case the parameters for this project have changed dramatically since I last shrubbed this project, which was pre obtaining a GPU.

If I let the WU's continue (as I really don't like aborting) what credit can I expect?

Basically not worth the time versus the credit for CPU tasks now.

WU's aborted although I hate doing that.
