Hello, The FAQ states: "Support for MPI_THREAD_MULTIPLE [...] has been designed into Open MPI from its first planning meetings. Support for MPI_THREAD_MULTIPLE is included in the first version of Open MPI, but it is only lightly tested and likely still has some bugs."
The man page of "mpirun" from v1.4.3a1r23323 in addition says "Open MPI is, currently, neither thread-safe nor async-signal-safe" (section "Process Termination / Signal Handling"). Are these statements up-to-date? What is the status of MPI_THREAD_MULTIPLE in OMPI 1.4? Thanks in advance for any info! Cheers, Riccardo
