Dumping ULT stacks
by Iwasaki, Shintaro 07 Sep '18

07 Sep '18

Hi, Johann, Thank you for suggestion. Currently, Argobots does not have functions printing ULT stacks. We don't know someone implemented things similar. However, stack dump should be very useful for debugging. Since it is needed, we will raise the priority of this issue. In github, the similar issue has been posted. https://github.com/pmodels/argobots/issues/12 I will add a technical comment about this issue soon. For example, printing all ULTs in a pool can be technically difficult because there is no general way to get all the ULTs in the pool. We would be happy if you would join the discussion.

We found ABT_info_print_all_xstreams(), but it does not print any ULT stacks. Has anyone already implemented something similar? Thanks in advance.
