Description:   Opened: 2004-01-14 13:09 0000 
pthreads uses USR1 and the default compile options for mpich uses USR1 as well.


Proposed Solution: For some time now, i have successfully used them concurrently with mpich compiled with SIGUSR2 (12) or SIGBUS (7).

Reproducible: Always
Steps to Reproduce:




I have a patch.  I will upload once bug created.

patch for mpich ebuild to support alternate signals for listener


Here is a patch which enables two new use variables.  Namely mpi_sigbus and
mpi_sigusr2.  each changes the compile time options of mpich to listent to the
respective signal instead of sicusr1.

um, can I do something to help move this along?

Anybody got something to say about this? I'm mostly fine with it, but instead
of USE flags I'd just have an environment variable.

For example, `LISTENER_SIG="foo" emerge mpich`.

patch for mpich ebuild to support user specified configure string

Guess this didn't make it into the latest ebuild so here is a patch against the
latest.

I'm going to assume there is a good reason why 'export FOO="w00t"' is not
typical in ebuilds and follow suit with two lines

oops...  usage info...  I have tested with and without
'MPICH_CONFIGURE_OPTION="--with-device=ch_p4:-listener_sig=SIGBUS"' in my
make.conf without issue on x86.

In CVS. Please test.
