osd_cat – X on-screen file displayer Synopsisosd_cat [OPTION] [FILE]… osd_cat -b percentage|slider [OPTION] DescriptionDisplay FILE, or standard input, on X screen. -p, –pos=POS This option tells osd_cat where to display the text. POS can be top, middle, or bottom. The default is top. -o, –offset=OFFSET This option specifies the offset from the top or bottom…
osage – filter for drawing clustered graphs Synopsisosage [–(G|N|E)name=value] [-Tlang] [-llibfile] [-ooutfile] [-O] [-P] [-v] [-V] [files] Descriptionosage draws clustered graphs. As input, it takes any graph in the dot format. It draws the graph recursively. At each level, there will be a collection of nodes and a collection of cluster subgraphs. The internals of…
os-prober — Discover bootable partitions on the local system. Synopsisos-prober DescriptionThe os-prober utility will scan all disks available on the system for other operating systems. For each discovered OS, it will output a line of the form: <partition>:<descriptive name>:<short name>:<kind of loader> For example, on system with Windows XP installed on /dev/sda1, os-prober will display:…
orterun, mpirun, mpiexec – Execute serial and parallel jobs in Open MPI. oshrun, shmemrun – Execute serial and parallel jobs in Open SHMEM. Note: mpirun, mpiexec, and orterun are all synonyms for each other as well as oshrun, shmemrun in case Open SHMEM is installed. Using any of the names will produce the same behavior….
orted – Start an Open RTE User-Level Daemon Synopsisorted [options] Descriptionorted starts an Open RTE daemon for the Open MPI system. NoteThe orted command is not intended to be manually invoked by end users. It is part of the Open MPI architecture and is invoked automatically as necessary. This man page is mainly intended for…
opal_wrapper – Back-end Open MPI wrapper command Synopsisopal_wrapper [options] Descriptionopal_wrapper is not meant to be called directly by end users. It is automatically invoked as the back-end by the Open MPI wrapper commands such as: mpicc, mpiCC, mpic++, and mpifort (and its legacy/deprecated names mpif77 and mpif90). Some Open MPI installations may have additional wrapper…
