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.
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.
