Hi, In Open MPI 1.4.1, the directory lib/openmpi contains about 130 entries, including such things as mca_btl_openib.so. In my build of Open MPI 1.4.2, lib/openmpi contains exactly three items: libompi_dbg_msgq.a libompi_dbg_msgq.la libompi_dbg_msgq.so
I have searched my 1.4.2 installation for mca_btl_openib.so, to no avail. And yet, 1.4.2 seems to work "fine". Is my installation broken, or is the organization significantly different between the two versions? A quick scan of the release notes didn't help. Thanks! -- Best regards, David Turner User Services Group email: dptur...@lbl.gov NERSC Division phone: (510) 486-4027 Lawrence Berkeley Lab fax: (510) 486-4316
