Sets the control group for the process being added to the group ID specified by gid. This group must already exist. (The CLI GROUPS variable contains a list of all groups.)
{ -np | -procs | -tasks } num
Indicates the number of processes or tasks that the starter program creates.
-nodesnum
Indicates the number of nodes upon which your program will execute.
-replay | -no_replay
These options enable and disable the ReplayEngine the next time the program is restarted. To enable, the feature must be supported and licensed on the current platform.
-starter_argsargument
Indicates additional arguments to be passed to the starter program.
-envvariable=value
Sets a variable that is added to the program’s environment.
Adds, changes, or removes an environment variable in the target process. A target process inherits its environment from its parent process, but this option allows you to modify the environment passed to target processes created by the debugger. If the variable does not exist in the inherited environment, it is inserted with the given value. If the variable already exists in the inherited environment, it is replaced with the given value. In either case, value can be an empty string. If the string contains no equal sign, then variable is removed from the inherited environment.
Multiple -env options may be specified.
-e
Indicates that the next argument is an executable file name. You need to use -e if the executable name begins with a dash (-) or consists of only numeric characters. Otherwise, just provide the executable file name.
executable
A fully or partially qualified file name for the file corresponding to the program.
-parallel_attach_subsetsubset_specification
Defines a list of MPI ranks to attach to when an MPI job is created or attached to. The list is space-separated; each element can have one of three forms:
rank: specifies that rank only
rank1-rank2: specifies all ranks between rank1 and rank2, inclusive
rank1-rank2:stride: specifies every strideth rank between rank1 and rank2
A rank must be either a positive decimal integer or max (the last rank in the MPI job).
A subset_specification that is the empty string ("") is equivalent to 0-max.
will attach to ranks 1, 2, 4, 5, 6, 7, 9, 11, 13,...
-list_reverse_connect
Lists all the available reverse connect requests that are found. Each request is preceded by the reverse connect ID.
-reject_reverse_connect [ ID | all ]
Rejects a reverse connection.
If an ID is specified, then that specific request is rejected. The waiting back end initiating the request will be terminated. If "all" is specified, then all requests found will be rejected. If no ID is specified, the first request seen will be rejected.
-accept_reverse_connect [ ID ]
Accepts a reverse connection.
If an ID is specified, then that specific request is accepted. If no ID is specified, the first request seen will be accepted.
Description
The dload command creates a new TotalView process object for the executable file and returns its TotalView ID.
NOTE >> Your license limits the number of processes that you can run at the same time.

Description
lo
dload
Loads debugging information
lo -list_rc
dload -list_reverse_connect
Lists any reverse connection requests found
lo -reject_rc
dload -reject_reverse_connect
Reject either all or one reverse connection requests
dload -accept_rc
dload -accept_reverse_connect
Accept either all or one reverse connection requests
Examples
dload do_this
Loads the debugging information for the do_this executable into the CLI. After this command completes, the process does not yet exist and no address space or memory is allocated to it.
dload -mpi POE -starter_args "hfile=~/my_hosts" \
-np 2 -nodes
Loads an MPI job using the POE configuration. Two processes will be used across nodes. The hfiles starter argument is used.
lo -g 3 -r other_computer do_this
Loads the debugging information for the do_this executable that is executing on the other_computer machine into the CLI. This process is placed into group 3.
f g3 lo -r other_computer do_this
Does not do what you would expect it to do because the dload command ignores the focus command. Instead, this does exactly the same thing as the previous example.
dload -g $CGROUP(2) -r slowhost foo
Loads another process based on image foo on machine slowhost. The CLI places this process in the same group as process 2.
dload -env DISPLAY=aurora:0.0
-env STARTER=~/starter myprog
Sets up two environment variables $DISPLAY and $STARTER for the program myprog and loads myprog's debugging information.
