ssrun - set up and run a process to collect SpeedShop performance data
ssrun [options] command [args]
ssrun is used by the SpeedShop performance tools to establish the
environment to capture performance data for an executable, and create a
process from the executable (or an instrumented version), and then run
it. When performance data is collected, it is written to a file whose
name is of the form <command>.<exptype>.<code><pid> where <code> can be
'm' for the master process created by ssrun, 'p' for a process created by
a call to sproc(), 'f' for a process created by a call to fork(), 'e' for
a process created by a call to exec(), 's' for a system call process and
'fe' for a process created by a call to fork() and exec() with
environment variable _SPEEDSHOP_TRACE_FORK_TO_EXEC being set to False.
Data may be examined using prof(1).
The following options may be given:
- <exptype> | -exp <exptype>
Specifies the type of SpeedShop experiment to run. The value of
<exptype> specifies the particular performance data that will be
recorded during the run. See the speedshop(1) man page for the list
of supported experiments. Some experiments require that the target
process be instrumented to collect data; if necessary,
instrumentation (by pixie(1)) will be performed, and the resultant
instrumented executable run. The experiment type may also be set by
setting the environment variable _SPEEDSHOP_EXPERIMENT_TYPE. If
both are set, and they are different, a warning message will be
printed, and the command line argument will prevail.
Each experiment type corresponds to a set of "marching orders" that
the runtime will use. This facility is provided to allow users to
specify customized experiments, and will be more fully documented in
subsequent releases. Marching orders may also be set by setting the
environment variable _SPEEDSHOP_MARCHING_ORDERS, or by providing a
mo argument to ssrun. If a known experiment is specified, and the
marching orders are also specified, and they are different, a
warning will be printed, and the marching orders will prevail. If
the experiment is not known, its name will be used and no warning
issued; if no experiment name was specified, the experiment name
will be set to "marching-orders".
-mo marching-orders
Specifies marching orders; if this option is used, the environment
variable _SPEEDSHOP_MARCHING_ORDERS will not be examined.
-purify
Specifies (if the independent Purify product is installed), that
purify should be run on the target, and the resulting purify'd
executable run. Note that -purify and SpeedShop performance

experiments can not be combined.
-v | -verbose
Specifies that a log of the operation of ssrun should be printed to
stderr. The same behavior occurs if the environment variable
_SPEEDSHOP_VERBOSE is set a to a zero-length string.
-V Specifies that a detailed log of the operation of ssrun should be
printed to stderr. The same behavior occurs if the environment
variable _SPEEDSHOP_VERBOSE is set a to a non-zero-length string.
In this case, a non-zero-length _SPEEDSHOP_VERBOSE environment
variable will be set, so that the target and any descendant
processes will see it.
-workshop
Forces special instrumentation so that the experiment files can be
read by WorkShop's cvperf analyzer unless one of the capture modules
of the experiment also requires instrumentation.
-quiet
Suppresses all output other than error messages. If set,
_SPEEDSHOP_SILENT will be set, so that the target and any descendant
processes will see it.
-hang
Specifies that the process should be left waiting just before
executing its first instruction.
-port hostname portno
Specifies that the process is to be left waiting, and, in addition,
notifications of status be sent to the socket on the host given by
hostname and port given by portno from the command line. When the
process is ready, a message of the form "running <pid> <host>" will
be sent to inform the requestor of the target process' PID, and
(possibly remote) host. A debugger may then attach to it and take
control of its execution.
-x Specifies that the process is to be left waiting, and, in addition,
that the window of the WorkShop Debugger requesting the creation (as
given by the display-id and window-id on the command line) be
informed of the target process' PID. A debugger may then attach to
it and take control of its execution.
-name target-name
Specifies that the target, instrumented or not, should be run with
argv[0] set to target-name. Normally, both instrumented and
uninstrumented executables are run with argv[0] set to the original
name.
