Hi Vlad,

Since the 19th August I have a number of tasks that have been marked as invalid.
The tasks are failing unless they have been run on a GPU under linux.

For example this task: http://xansons4cod.com/xansons4cod/workunit.php?wuid=6396703
Some of the tasks are lucky and got 2 linux GPUs but others failed completely.

It isn't a lot, only 185 invalid out of the thousands I do but did something go wrong with these ?

Hi PDW,

Thank you for reporting this. Some crystallographic information files (CIFs) in the COD may contain errors. CIFs for failed WUs were uploaded to the COD by the same research group, so all these CIFs probably have the same problem. What is really interesting is why some of the WUs were successfully completed in Linux. I'll try to figure this out.

Update
I found what was wrong with these CIFs and updated the CIF to XML converter, so this error should not occur in the future. Despite passing the validation test, the results obtained in Linux were also incorrect. Failed WUs will be resubmitted when all the COD data is processed.

Okay, good to know and get it corrected :)

Didn't realise you had updated your post to say you'd fixed it.

Not sure if connected but the completed calculation has been stuck at 49.27% for a while now on the server status page ?

Had been hoping to post this...

It was not connected. The part of the assimilator responsible for merging the results failed and therefore the statistics stuck. It's fixed now. Thanks for reporting this! And yes, we are half way there)!
