Algorithm running over 5 hours

Algorithm running over 5 hours

Dear Organizers,

Thanks for your efforts for bringing the nice challenge so far.

I have made one submission but the status keeps showing "executing algorithm" for over 5 hours. I have tested the same docker on 8 cases locally and it only took one or two minutes, so there must be some issues on running the docker on grand challenge.

Could you please provide some guidance on this issue? Many thanks!

Best wishes, Yuliang

Just to update, the status is now "Failed Time limit exceeded".

However, when I checked the results, I can see that the algorithm was successfully run on all the 8 validation cases.

The first case started 8 hours ago while the rest all started 3 hours ago, and each case took just several seconds for actually running the algorithm (total duration is 2 minutes per case including reading and saving images).

I am not quite sure why it said my algorithm took too long to finish.

Hello Yuliang,

thank you for your interest in our challenge.

Apologies for the inconvenience you experienced. I am happy to report that I was able to "fix" the issue and that your algorithm submission was successful and is now part of the leaderboard.

Future uploads by you should work immediately.

The issue arose from an update the the Grand Challenge platform about two days after the start of the preliminary testing phase. This update removed the "started_at" and "completed_at" timestamps which we where using to automatically compute the runtime of each algorithm. There will be an additional forum post with more details in a minute.

Sincerely, Tom
