9.9. Deprecated options

These deprecated options will be removed in a future release.

Deprecated Option	Replacement	Description
--bind-to-core	--bind-to core	Bind processes to cores
--bind-to-socket	--bind-to package	Bind processes to processor sockets
--bycore	--map-by core	Map processes by core
--bynode	--map-by node	Launch processes one per node, cycling by node in a round-robin fashion. This spreads processes evenly among nodes and assigns ranks in a round-robin, “by node” manner.
--byslot	--map-by slot	Map and rank processes round-robin by slot
--cpus-per-proc <#perproc>	–map-by <obj>:PE=<#perproc>`	Bind each process to the specified number of CPUs
--cpus-per-rank <#perrank>	--map-by <obj>:PE=<#perrank>	Alias for --cpus-per-proc
--display-allocation	--display ALLOC	Display the detected resource allocation
-display-devel-map	--display MAP-DEVEL	Display a detailed process map (mostly intended for developers) just before launch.
--display-map	--display MAP	Display a table showing the mapped location of each process prior to launch.
--display-topo	--display TOPO	Display the topology as part of the process map (mostly intended for developers) just before launch.
--do-not-launch	--map-by :DONOTLAUNCH	Perform all necessary operations to prepare to launch the application, but do not actually launch it (usually used to test mapping patterns).
--do-not-resolve	--map-by :DONOTRESOLVE	Do not attempt to resolve interfaces — usually used to determine proposed process placement/binding prior to obtaining an allocation.
-N <num>	--map-by prr:<num>:node	Launch num processes per node on all allocated nodes
--nolocal	--map-by :NOLOCAL	Do not run any copies of the launched application on the same node as prun is running. This option will override listing the localhost with --host or any other host-specifying mechanism.
--nooversubscribe	--map-by :NOOVERSUBSCRIBE	Do not oversubscribe any nodes; error (without starting any processes) if the requested number of processes would cause oversubscription. This option implicitly sets “max_slots” equal to the “slots” value for each node. (Enabled by default).
--npernode <#pernode>	--map-by ppr:<#pernode>:node	On each node, launch this many processes
--npersocket <#persocket>	--map-by ppr:<#perpackage>:package	On each node, launch this many processes times the number of processor sockets on the node. The --npersocket option also turns on the --bind-to socket option. The term socket has been globally replaced with package.
--oversubscribe	--map-by :OVERSUBSCRIBE	Nodes are allowed to be oversubscribed, even on a managed system, and overloading of processing elements.
--pernode	--map-by ppr:1:node	On each node, launch one process
--ppr	–map-by ppr:<list>`	Comma-separated list of number of processes on a given resource type [default: none].
--rankfile <FILENAME>	--map-by rankfile:FILE=<FILENAME>	Use a rankfile for mapping/ranking/binding
--report-bindings	--display BINDINGS	Report any bindings for launched processes
--tag-output	--output TAG	Tag all output with [job,rank]
--timestamp-output	--output TIMESTAMP	Timestamp all application process output
--use-hwthread-cpus	--map-by :HWTCPUS	Use hardware threads as independent CPUs
--xml	--output XML	Provide all output in XML format
