Here are the runs I started if these give you any errors please post here:

You folks might want to collaborate with scientists who specialize in areas that have nothing to do with astronomy. Sometimes the techniques they used to solve their problems will work for your problems. ORSA and TIMS come to mind.

The algorithms used to solve positioning problems for optical pattern recognition might be helpful to "normalize" distorted data patterns created by any number of aberrations beyond our control.

For example, a scientist struggled to design a way to monitor and control traffic patterns. He found the answer to his need from an aeronautical engineer who specialized in the dynamics of compressible gases. It seems that the reaction speed and observation limitations of human drivers matched feedback loops caused by turbulence in air flow over wing surfaces.

BTW, MySQL has both advantages and limitations for scientific work. One advantage is the ability to manage data at the bit level. Its disadvantage is scalability problems.

It is not consistent but some of these runs crash the display driver, which the OS will catch and will then restart, the run will continue to execute, and finally post a result with a computational error.

All of these work units end in computational errors on my computer. Running Win7 Home with a AMD 5870 card.

Me too. Seemingly the WU barely starts and is stopped to start another. Is there a download error?

Your card does not support the double precision necessary for this project.

Last valid unit
since then receives some 7-8 Hourly Jobs.
who go too long, it is not possible to calculate them in 7-8 hours
so completely wrong everything. since yesterday

Regrettably, I have to abort these runs as I get a computational error each time.

Running ATI 5830 on a AMD Sabertooth w/8370 processor.
