Yesterday(or maybe the day before) boinc on my computer reported that there's "an calculation error". How come? I just can't understand how a calculation error would happen, since if it could occur while running seti@home, there's no reason that it wouldn't happen when performing other tasks. But I haven't come across mistakes more than programming errors, or bugs.
The task name is 16no06ab.20233.9479.10.37.84
I received it on Feb 1th 3:51 p.m.
May you explain what does suck kind of problem mean or may you(emmm, my request seems to be unreasonable) look into the insident?

One occasional error is not really anything to worry about. Can be due to lots of things.

Only start worrying if it happens often

I just want to know how it happened. May it because that wrong data was sent? Is there a slight hardware failure in the CPU? Or did a cosmic ray hit the CPU, as is described in science fiction? Will it occur in other programs, when performing a simple logical operation? At least I can only imagine mistakes caused by human errors, such as programming mistakes.

Nothing so dramatic. The Seti science application keeps track of what's happening to the data it is calculating. If results stray out of boundaries, the task will be aborted, usually with a compute error (is what it's called in BOINC). Your task erred with computation error -194 (I saw earlier today) which can mean that the project aborted the task. I don't say that happened, but it's a possibility. Else it's just a myriad of options and oddities that can happen by which a task doesn't finish correctly. As Bernie said, don't sweat it, if it happens once or twice in a day. Only worry about it when it happens all the time, as then either there's something wrong with the batch of tasks, or with your computer. Now neither of those cases is true.

All right. Thanks.
