disable the building of the udapl BTL on Linux by default. On every other OS, the udapl configury will attempt to find udapl's header/library files, etc. by default. You can specify --with-udapl on the configure command line (on any OS) to force OMPI to try to configure/build udapl (i.e., look for udapl's header/library files, etc.). This commit was SVN r15894.

# Special case for OFED/Linux: the default /etc/dat.conf that
|
|
# ships with OFED is broken in that it includes DAT providers that
|
|
# are not guarnateed to work (e.g., it includes providers for ib0,
|
|
# ib1, ib2, ib3, and bond0). Usually, a sysadmin will need to
|
|
# edit this file to configure it for the specific environment in
|
|
# which it will be used. Hence, if you run the udapl BTL on
|
|
# Linux/OFED, you'll get a bunch of warning messages about the
|
|
# providers that don't work. However, on Linux/OFED, you don't
|
|
# really want to use udapl anyway; you likely really want to use
|
|
# the openib BTL (i.e., native verbs, not udapl).
|
|
|
|
# So after exploring many different scenarios, the least evil
|
|
# solution seemed to be to disable building the udapl BTL on
|
|
# Linux/OFED *unless the user specifically asks for it.* To be
|
|
# specific: on Linux/OFED, if you do not specify
|
|
# --with-udapl(=DIR), the udapl BTL will not be built.
