Just pushed a commit to master that should support many processing elements. Thanks for the report. Ken On 11/18/2015 10:24 AM, Kenneth Raffenetti wrote:
The newline is added after all the hwthreads are added to the string - line 469. You might be overrunning the max string length, as that is not well handled. Can you try doubling DBG_STR_LENGTH at the top of the file?

but got a huge mess rather than the output shown on the Wiki.
Is the lack of line break here intentional? I think it would be more useful if it did.

The offending line appears to be 463 in src/pm/hydra/tools/topo/hwloc/topo_hwloc.c, but I don't know if the "\n" goes there or in the definition of HYDU_snprintf.
