OOMMF and Process ID Information: pidinfo

The pidinfo command prints a table mapping OOMMF ID's (OID's) to system process ID's (PID's) and application names.

The pidinfo command line is:

tclsh oommf.tcl pidinfo [standard options] [-account name] \
   [-hostport port] [-names] [-noheader] [-pid] [-ports] \
   [-timeout secs] [-wait secs] [-v] [oid ...]
-account name
Specify the account name. The default is the same used by mmLaunch: the current user login name, except on Windows 9X, where the dummy account ID ``oommf'' may be used instead.
-hostport port
Use the host server listening on port. Default is set by the Net_Host port setting in oommf/config/options.tcl, or by the environment variable OOMMF_HOSTPORT (which, if set, overrides the former). The standard setting is 15136.
Display application nicknames, which are used by the MIF 2.1 Destination command.
Don't print column headers.
Select processes by system pid rather than OOMMF oid.
Display active server ports for each application.
-timeout secs
Maximum time to wait for response from servers, in seconds. Default is five seconds.
Display information about the host and account servers.
-wait secs
If no match is found, then retry for up to secs seconds. Default is zero seconds, i.e., try once.
oid ...
List of OOMMF ID's to display information about. Default is all current applications. If the -pid option is specified then this selection is by system process ID's rather than OOMMF ID's.
The title bar of running OOMMF applications typically displays the application OID, which are used by OOMMF applications to identify one another. These ID's start at 0 and are incremented each time a newly launched application registers with the account server. The OID's are independent of the operating system PID's. The PID is needed to obtain information, e.g., resource use, about a running process using system utilities. The PID may also be needed to invoke the operating system ``kill'' facility to terminate a rogue OOMMF application. The pidinfo application can be used to correspond OID's or OOMMF application names to PID's for such purposes.
