DESCRIPTION

     fractalpooluser is a Reliable Server Pooling (RSerPool) pool user (PU)
     for the FractalGenerator service. It uses a Qt-based X11 GUI.

ARGUMENTS

     The following options are available:

     -identifier=PU_identifier
             Sets a fixed PU identifier. Handle with care!

     -poolhandle=pool_handle
             Sets the PH to a non-default value; otherwise, the default
             setting is "FractalGeneratorPool".

     Service Parameters:

             -configdir=directory
                     Sets a directory to look for FGP config files. From all
                     FGP files (pattern: *.fgp) in this directory, random
                     files are selected for the calculation of requests.

             -caption=window_title
                     Sets the output window title.

             -width=pixels
                     Sets the width of the window and the images to be
                     calculated.

             -height=pixels
                     Sets the height of the window and the images to be
                     calculated.

             -threads=threads
                     Sets the number of parallel sessions to use for
                     processing of each image.

             -sendtimeout=milliseconds
                     Sets the transmission timeout.

             -recvtimeout=milliseconds
                     Sets the receive timeout.

             -interimagetime=seconds
                     Sets the pause time between two image calculations in
                     seconds.

             -imagestorageprefix=file_name_prefix
                     Sets a file name prefix for saving the calculated images.
                     If set, each successfully calculated image is stored to
                     the given location as PNG file, with a 6-digit file
                     number added.

             -colormarks
                     Turns on color change on session failover.

             -nocolormarks
                     Turns off color change on session failover.

             -sessions
                     Turns on color change between different sessions.

             -nosessions
                     Turns off color change between different sessions.

     ASAP Protocol Parameters:

             -registrar=address:port
                     Adds a static PR entry into the Registrar Table.  It is
                     possible to add multiple entries.

             -registrarannouncetimeout=milliseconds
                     Sets the timeout for ASAP announces via multicast.

             -registrarconnecttimeout=milliseconds
                     Sets the timeout for ASAP connection establishment.

             -registrarconnectmaxtrials=trials
                     Sets the maximum number of ASAP connection establishment
                     trials.

             -registrarrequesttimeout=milliseconds
                     Sets the timeout for ASAP requests.

             -registrarresponsetimeout=milliseconds
                     Sets the timeout for waiting to receive ASAP responses.

             -registrarrequestmaxtrials=trials
                     Sets the maximum number of ASAP request trials.

     Component Status Protocol (CSP) Parameters:

             -cspserver=address:port
                     Sets the address of a CSP monitor server. By default, the
                     content of the environment variable CSP_SERVER is used.
                     If not defined, no CSP status reports will be sent.

             -cspinterval=milliseconds
                     Sets the interval for the CSP status updates in
                     milliseconds. By default, the content of the environment
                     variable CSP_INTERVAL is used. If not defined, no CSP
                     status reports will be sent.

     Logging Parameters:

             -logappend=filename
                     Write logging output to a file (default is stdout);
                     output will be appended to given file.

             -logcolor=on|off
                     Turns ANSI colorization of the logging output on or off.

             -logfile=filename
                     Write logging output to a file (default is stdout); given
                     file will be overwritten.

             -loglevel=0-9
                     Sets the logging verbosity from 0 (none) to 9 (very
                     verbose).  It is recommended to use at least a value of 2
                     to see possibly important error messages and warnings.

ENVIRONMENT

     fractalpooluser uses the environment variables CSP_SERVER and
     CSP_INTERVAL to define a CSP server to send reports to in the specified
     interval.

DIAGNOSTICS

     If loglevel>0, log messages will be printed to stdout or into a specified
     log file.
