Submitting reports

  • Before submitting a report, please take a look at the currently open tickets and see if your issue is already known.
  • If you are a known reporter or developer (i.e., you have been given login information for our Trac), please create a new ticket.
  • Otherwise, send an email to File:Bccd-dev_email.png
  • In both cases, include the following information:
    • Major version number (at this time either 2.2 or 3.0)
    • Revision number and date (this can be found by doing bccd-version in a running BCCD instance)
    • Live or Liberated? (this can be found by doing cat /etc/bccd-stage in a running BCCD instance)
    • Short description of problem
    • The steps you took up to the problematic event
    • Any extra details you might be able to provide

Example report

Version: 3.0
Revision: r2300, 03/31/10
Both live and liberated

The Life application does not appear to run with a single process while using MPICH2.

Steps to reproduce:
- Boot a single node (standalone or otherwise; appears to not matter)
- Unload openmpi and load mpich2:
-- module unload openmpi && module load mpich2
- Build Life:
-- cd Life; make clean && make
- Run with -np 1:
-- mpirun -np 1 ./Life

The Life display opens, but no changes ever happen. The display hangs like this until the user manually
kills the process. Further inspection shows that the one Life process takes up 100% CPU and, as shown
by strace, is in an infinite active polling loop.
