Subject: [OMPI users] pml_v question
From: Leonardo Fialho (lfialho_at_[hidden])

Hi All,

I´m trying to use the pml_v (pessimist) with FT components, but during
the loading the pml_v closes and close the vprotocol_pessimist too...
according the following:

(log of only one process...)

$ mpirun -np 2 -hostfile ../hostfile -am ../ft-enable-cr -v -d ./ping 10 1

The MCA parameters are (except the verbose parameters):

snapc_base_store_in_place=0
opal_cr_allow_opal_only=0
mca_base_component_distill_checkpoint_ready=0
ft_cr_enabled=1
crs=
rml_wrapper=ftrm
snapc=single (similar to full but do a checkpoint of only one process)
filem=rsh
pml_wrapper=crcpw
crcp=uncoord (similar to coord but need to do checkpoint of only one
process)
btl=tcp,self

Thanks,
Leonardo Fialho
