Subject: Re: [OMPI users] usNIC point-to-point messaging module

Dear Ralph, Dear Jeff,

I've just recompiled the latest Open MPI 1.8. I added "--enable-mca-no-build=btl-usnic" to configure but the message still appear. Here the output of "--mca btl_base_verbose 100" (trunked immediately after the application starts)

srun: cluster configuration lacks support for cpu binding
