BOINC science applications and random crashes (Update)


 

 

Results on RALPH@Home which is R@H’s alpha project have been very promising.

 

To give an idea about how large this problem was for R@H I guess I need to provide some numbers.  So here goes:

 

R@H receives roughly 115k results a day.

 

Roughly there are 16k failures a day.

 

Of those 16k failures a day, 5.5k fell under the ERR_NESTED_UNHANDLED_EXCEPTION_DETECTED and 0xc0000005 banner.  Those are the two error codes used when something really really really bad has happened on Windows.  There are another 1.5k errors that have cryptic Windows error codes which may or may not be related.

 

Now how does this translate to RALPH@Home?  Well if you work under the assumption that RALPH@home is a mini R@H, then the percentages should be roughly the same.

 

That said, sure enough RALPH@Home had roughly the same breakdown of errors that the public project had.  Here are some rough stats for RALPH@Home:

 

RALPH@Home receives roughly 1k results a day.

 

Before 4.93 was released for Beta the failure rate was 150 or so a day.

 

Now with 4.93 in the mix it has dropped to 100 or so a day.

 

Keep in mind that the Mac and Linux clients have not been updated yet and so there error rates remain unchanged.

 

RALPH@Home went from a 25% failure rate down to a 12% failure rate.  Now if you remove the results from Linux and the Mac the failure rate for the Windows client is floating at 5%.

 

I’ll include the current error rates in the public project and RALPH@Home below.

 

Now I’m on to the next biggest problem which has been deemed the ‘1% bug’.

 

For those who noticed the error code 1 in the charts below, that error code is given when Rosetta could not find something in one of the pre-staged files downloaded to your machine or when the application felt something really bad has happened and it couldn’t continue.  With 4.82 that actual error data was being written to a different log file than the one BOINC sends back to the server.  Starting with 4.94 the reason for the application quitting will be logged and sent back to the server in a way that can be easily tracked and fixed without having to write the workunit names in the forums.
