Hi Alian, I’ve seen this problem before but it appears to affect very few people so I’ve not needed to fix it. Perhaps the time has come to address it. Was bjam passed a -j option, if so, what was it? — Noel On Oct 20, 2014, at 9:33 AM, Alain Miniussi <alain.miniussi@oca.eu> wrote:
Hi,
I am trying to test Boost.MPI with Intel's implementation and I am stuck while trying to run simple tests through bjam. Bjam is hangs on the select (not pselect ?) instruction of the unix exec_wait. As far as processes are concerned:
PID USER PR NI S %CPU TIME+ PPID COMMAND ....................... 16882 alainm 20 0 S 0.0 0:01.61 6507 bjam 16899 alainm 20 0 T 0.0 0:00.00 16882 sh 16900 alainm 20 0 Z 0.0 0:00.00 16899 mpiexec.hydra <defunct> .......
bjam calls a generated shell (below) which calls a mpiexe.hydra which work perfectly fine outside bjam. The mpiexec.hydra dies the the shell refuses to let it go.
the shell script, generated by bjam, is:

[alainm@gurney engine]$ =================================================
Note that select only test for the subprocess output, at the hanging point mpiexec.hydra is done with its outputs.
Any idea ?
Alain
PS: there was a cmake based project some time ago, is it still active or is bjam here to stay ?
