Subject: [OMPI users] mca_pml_ob1_send blocks
From: Shaun Jackman (sjackman_at_[hidden])

Hi,

I'm seeing MPI_Send block in mca_pml_ob1_send. The packet is shorter
than the eager transmit limit for shared memory (3300 bytes < 4096
bytes). I'm trying to determine if MPI_Send is blocking due to a
deadlock. Will MPI_Send block even when sending a packet eagerly?

Thanks,
Shaun
