The old climate change program did not have such a limitiation. This restriction appears to me to be very stupid, with no logical reason. If my machine had not finished it\'s work it would not be asking for more. ID: 20381 · Reply Quote

It was to stop computers that were having problems hammering the servers fruitlessly. As the new workunits take many weeks even on fast computers, repeated requests can only indicate some sort of failure, and slow drip feeding is best. Waiting a day makes little difference in the long run. ID: 20383 · Reply Quote

My machine ran continuously for 24/7 for 6 months without stopping. I never saw one break in the whole of that period or any breaks waiting for data. Your answer does not stack up.

Peter Your models had barely started to run when they crashed. Which is the REAL reason 2 more were requested. Again this answer does not stack up as the message said that all the work had been done and was not going to load any more that day. On power up it loaded down more data and started again.

You started a WU and it crashed. We can see that in your account. Fine, you machine can run 6 months straight without a crash, that is without the processor being taxed. This software pegs your processor as far as it can go. If the processor has an issue with this (heat or other reason), or your memory is having issues that are not easily appearent, this could be the reasons for your sending back invalid units. These programs also use the FPU a lot more than any other. Many machines run for years and never show a problem, until it\'s stressed. Please test your system with programs like Prime95 and Memtest86+. These will help determine if you have issues. ID: 20394 · Reply Quote
