Upon startup, one service has to be selected by the command-line parameters. To start multiple services, run multiple instances. rspserver provides the following services: CalcApp Calculation application model for performance tests. See https://- duepublico.uni-duisburg-essen.de/servlets/DerivateServlet/Deri- vate-16326/Dre2006_final.pdf for more information. CharGen Sending as much character data as possible. Daytime Sending back current time of day. Discard Discarding incoming data. Echo Echoing back incoming data. Fractal Fractal generator with cookie-based failover. PingPong Simple request-response example using cookies for failover. Scripting Remote execution of scripts with upload/download of input/output data. Could for example be used for distributing simulation runs. Take care of security when using this service! ARGUMENTS The following options are available: Common Pool Element Parameters: -local=address:port,address,... Sets the local endpoint address(es). -asapannounce=address:port|auto|off Sets the multicast address and port the ASAP instance lis- tens for ASAP Server Announces on. -identifier=PE_identifier Sets a fixed PE identifier. Handle with care! -policy=policy_specification Sets the pool policy and its parameters (default is Round Robin). Supported policy specifications: RoundRobin (default policy) WeightedRoundRobin:weight Random WeightedRandom:weight LeastUsed LeastUsedDegradation:increment PriorityLeastUsed:increment LeastUsedDPF:dpf_value Priority:priority ... -poolhandle=pool_handle Sets the PH to a non-default value; otherwise, the default setting is the service-specific default. -quiet Do not print startup and shutdown messages. -rereginterval=milliseconds Sets the PE's re-registration interval. -runtime=seconds After the configured number of seconds, the service is shut down. Floating-point values (e.g. 30.125) are possible. -uptime=seconds After negative exponential randomized uptime, the PE ser- vice goes down for a configured downtime. After that, it comes up again. This option can be used for testing the failure handling procedures. -downtime=seconds After negative exponential randomized downtime, the PE ser- vice comes up again. This option can be used for testing the failure handling procedures. 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 ver- bose). It is recommended to use at least a value of 2 to see possibly important error messages and warnings. 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: -cspinterval=milliseconds Sets the interval for the CSP status updates in millisec- onds. By default, the content of the environment variable CSP_INTERVAL is used. If not defined, no CSP status reports will be sent. -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. Service Parameters: -calcapp Starts the CalcApp service. -capcapacity=calculations_per_second Sets the service capacity in calculations per sec- ond. -capcleanshutdownprobability=probability Sets the probability for sending state cookies to all sessions before shutting down. -capcookiemaxcalculations=calculations Sets the cookie interval in calculations. -capcookiemaxtime=seconds Sets the cookie interval in seconds. -capkeepalivetransmissioninterval=milliseconds Sets the keep-alive transmission interval in mil- liseconds. -capkeepalivetimeoutinterval=milliseconds Sets the keep-alive timeout in milliseconds. -capmaxjobs=max_jobs Sets the an upper limit for the number of simulta- neous CalcApp requests. -capobject=name Sets the object name for scalar hierarchy. -capscalar=scalar_file Sets the name of vector scalar file to write. -capvector=vector_file Sets the name of vector output file to write. -chargen Starts the CharGen service. -chargenmaxthreads=threads Sets an upper limit for the number of simultaneous CharGen sessions. -daytime Starts the Daytime service. -discard Starts the Discard service. -echo Starts the Echo service. -fractal Starts the Fractal Generator service. -fgpcookiemaxpackets=messages Send cookie after given number of Data messages -fgpcookiemaxtime=milliseconds Send cookie after given number of milliseconds. -fgpfailureafter=messages After the set number of data packets, the server will terminate the connection in order to test failovers. -fgpmaxthreads=threads Sets an upper limit for the number of simultaneous Fractal Generator sessions. -fgptestmode Generate simple test pattern instead of calculating a fractal graphics (useful to conserve CPU power when debugging). -fgptransmittimeout=milliseconds Sets transmit timeout in milliseconds. -pingpong Starts the PingPong service. -pppfailureafter=messages After the set number of messages, the server will terminate the connection in order to test failovers. -pppmaxthreads=threads Sets an upper limit for the number of simultaneous PingPong sessions. -scripting Starts the Scripting service. -sskeyring=keyring The location of a GnuPG keyring to check the work packages and environments against. If a keyring is specified, only files that pass the validation are accepted. -sscachedirectory=directory Sets the environment cache directory. -sscachemaxentries=entries Sets the maximum number of environment cache en- tries. -sscachemaxsize=kibibytes Sets the maximum size of the environment cache in kibibytes. -sskeepaliveinterval=milliseconds Sets the keep-alive interval in milliseconds. -sskeepalivetimeout=milliseconds Sets the keep-alive timeout in milliseconds. -sskeeptempdirs Turns on keeping all temporary files for debugging. Handle with care! -ssmaxthreads=threads Sets an upper limit for the number of simultaneous sessions. -sstransmittimeout=milliseconds Sets the transmission timeout in milliseconds. ENVIRONMENT rspserver uses the environment variables CSP_SERVER and CSP_INTERVAL to de- fine 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.
