Unrecognized FT TYPE: LAM

[tonideleo]

Background information

I am trying to compile the new ompi 5.0.0rc2 to test the fault tolerance capability; however, at the end of ./configure --with-ft=LAM --prefix=... I get the following error:

*** Fault tolerance
checking if want fault tolerance... Support for C/R FT has been removed in OMPI 5.0
Unrecognized FT TYPE: LAM
configure: error: Cannot continue

Am I missing something? I thought the options were either LAM or cr.

Thank you very much for your time!

OMPI lost support for cr or LAM type of fault management. The only supported type is based on ULFM, enabled with --with-ft=mpi.
