Wrong command line, sigh.. # ompi_info -a | egrep 'MCA.*(btl_openib_ib_retry_count|btl_openib_ib_timeout)' MCA btl: parameter "btl_openib_ib_timeout" (current value: "20", data source: default value) MCA btl: parameter "btl_openib_ib_retry_count" (current value: "7", data source: default value) Even more oddly, the second run of the users job did print that 7 and 20 as the defaults. I suspect this is likely the result of the user accidentally using an earlier version of OMPI, not 1.4.5, for his first run.
