LAM 7.1.4/MPI 2 C++/ROMIO - Indiana University Arch: x86_64-pc-linux-gnu Prefix: /usr/lib/lam Configured by: buildd Configured on: Thu Apr 10 03:20:43 UTC 2014 Configure host: phianna SSI rpi: crtcp lamd sysv tcp usysv

----------------------------------------------------------------------------- Synopsis: lamboot [-b] [-d] [-h] [-H] [-l] [-s] [-v] [-V] [-x] [-nn] [-np] [-c <conf file>] [-prefix </lam/install/path/>] [-ssi <key> <value>] [<bhost>] Description: Start up a LAM universe Options: -b Use the faster boot algorithm; will only work if shell on all remote nodes is same as shell on local node -c Use <conf file> for start-up configuration. Unless you are a developer, you probably don't want to use this option. -d Print debugging messages (implies -v) -h Print this message -H Don't print the header -l Use local hostnname resolution (vs. centralized name lookup) -nn Don't add "-n" to the remote agent command line -np Do not force the execution of $HOME/.profile on remote hosts -prefix Use the LAM installation specified in </lam/install/path> -ssi Send arguments to various SSI modules. See the lamboot manpage for SSI options. -s Close stdout/stderr of the locally-launched LAM daemon -v Be verbose -V Print version and exit without booting -x Run nodes in fault tolerant mode <bhost> Use <bhost> as the boot schema -session-prefix Set the session prefix, overriding LAM_MPI_SESSION_PREFIX. -session-suffix Set the session suffix, overriding LAM_MPI_SESSION_SUFFIX. -withlamprefixpath Override the internal installation path. For internal use only, do not use unless you know what you are doing. Session directory: A LAM session directory will be created on each node where the LAM run-time environment is started. This directory must be unique to each node. It will be created in the form: <prefix>/lam-<username>@<hostname>[-<suffix>] <prefix> will be based on the following search order: 1. The value of the LAM_MPI_SESSION_PREFIX environment variable (if it exists). 2. The value of the TMPDIR environment variable (if it exists). 3. /tmp <suffix> will be based on the following search order (if a valid <suffix> is not found, it is not used): 1. The value of the LAM_MPI_SESSION_PREFIX environment variable (if it exists). 2. If running under a supported batch system, a unique job ID will be used. The suffix is specifically for the case where users need multiple LAM run-time environments on a single node (as is common in batch-queue environments). -----------------------------------------------------------------------------
