Maybe someone can help me from having to think too hard.
Let's say I want to max my system limits. I can say this: % mpirun --mca opal_set_max_sys_limits 1 ... Cool. Meanwhile, if I do this: % setenv OMPI_MCA_opal_set_max_sys_limits 1 % mpirun ...remote processes don't see the setting. (Local processes and ompi_info are fine.)
Bug? Naively, this looks "wrong." At least disturbing, in any case. This is with v1.5.
