These functions are available in Bourne shell (preferably using .MO bash 1 for greater efficiency), TCL, Perl, or Python scripts after sourcing/including the files jsv_inlcude.sh, jsv_include.tcl, JSV.pm, or JSV.py. The files and corresponding JSV script templates are located in the directory .IR $SGE_ROOT/util/resources/jsv . There is also a Java implementation which has a different structure, with Javadoc documentation normally in .IR $SGE_ROOT/doc/javadocs/jjsv , and example files .I SimpleJsv.java and .I jjsv.sh in .IR $SGE_ROOT/util/resources/jsv . .PP Note that Bourne shell server JSVs are discouraged because any problems with unintended expansion of job parameters represent a security hazard (with the qmaster running as the sgeadmin user). Also they may be relatively slow, and constitute a bottleneck in high-throughput clusters. However, shell JSVs may be faster using .M bash 1 , even compared with a generally faster shell, since fewer external commands are invoked. .PP In the descriptions of routines here, a calling sequence like .RS \fBfunction\fP(\fIarg1\fP, \fIarg2\fP) .RE should be interpreted for Bourne shell and Tcl scripts as .RS \fBfunction\fP \fIarg1\fP \fIarg2\fP .RE .\" .SS "jsv_clear_params()" This function clears all received job parameters that were stored during the last job verification process. .\" .SS "jsv_clear_envs()" This function clears all received job environment variables that were stored during the last job verification process. .\" .SS "jsv_show_params()" A call of this function reports all known job parameters to the counterpart of this script (client or master daemon thread). These parameters will be reported as info messages and appear either in the stdout stream of the client or in the message file of the master process. .\" .SS "jsv_show_envs()" This function reports all known job environment variables to the counterpart of this script (client or master daemon thread). They will be reported as info messages and appear in the stdout stream of the client or in the message file of the master process. .\" .SS "jsv_is_param(\fIparam_name\fP)" This function returns whether or not a specific job parameter is available for the job which is currently being verified. Either the string \fBtrue\fP or \fBfalse\fP will be returned. The availability/absence of a job parameter does not mean that the corresponding command line switch was used/not used. .PP The values allowed for \fIparam_name\fP are listed below. Find additional information in .M qsub 1 describing the availability and value format. Job parameters written in capital letters are pseudo parameters. A detailed description for them can be found in .M jsv 1 .

The outcome of the evaluation of all .BR \-ac , .BR \-dc , and .B \-sc options is passed as a parameter with the name .BR ac , whose value is a comma-separated list of variable/value pairs; .TP .BR binding_strategy ,\ binding_type ,\ binding_amount ,\ binding_step ,\ binding_socket ,\ binding_core ,\ binding_exp_n ,\ binding_exp_socket\fIid\fP ,\ binding_exp_core\fIid\fP The values passed to the .B \-binding parameter are passed as multiple parameters to JSV instances. .B binding_strategy represents the strategy to be used and is one of: .BR linear , .B striding or .BR explicit . .B binding_type is the instance that should do the binding, one of: .BR env , .B set or .BR pe . .B binding_socket and .B binding_core are socket/core values whereas .B binding_step is the step size (used only for striding binding). The length of the socket/core value list of the explicit binding is reported as .BR binding_exp_n . The .I id part of .BI binding_exp_socket id and .BI binding_exp_core id will be replaced by the position of the socket/core pair within the explicit binding list (0 <= .I id < \fBbinding_exp\fI_n\fR). The first socket/core pair of the explicit binding will be reported with the parameter names .B binding_exp_socket0 and .BR binding_exp_core0 . Values that do not apply for the specified binding will not be reported to JSV. E.g. .B binding_step will only be reported for the striding binding and all .B binding_exp_... values will only be passed if explicit binding was specified. .TP .B c_interval Checkpoint interval, specified as a numeric value with .BR \-c ; .TP .B c_occasion Checkpoint "occasion_specifier" .BR \-c . .BR "" ( n , .BR s , .BR m , or .BR x ) specified with .BR \-c ; .TP .B cwd Working directory, possibly specified with .B \-cwd or .BR \-wd ; .TP .B display Reflects the .B \-display submit argument and also sets job environment variable DISPLAY to the same value; .TP .B l_hard .B \-l or .B \-hard followed by .BR \-l ; .TP .B l_soft .B \-soft followed by .BR \-l ; .TP .BR pe_name ", " pe_min ", " pe_max The PE name and range limits specified with .BR \-pe ; .TP .B q_hard .BR \-q , or .B \-hard followed by .BR \-q ; .TP .B q_soft .B \-soft followed by .BR \-q . .PP See .M jsv 1 for explanation of the following pseudo parameters: .BR CLIENT , .BR CMDNAME , .BR CMDARGS , .BR CMDARG\fIi , .BR CONTEXT , .BR GROUP , .BR JOB_ID , .BR USER , .BR VERSION . .\" .SS "jsv_get_param(\fIparam_name\fP)" This function returns the value of a specific job parameter \fIparam_name\fP. .PP This value is only available if the function \fBjsv_is_param\fP() returns \fBtrue\fP.

This will slow down the executing component (submit client or master daemon thread). For this reason, job environment information is not passed to JSV scripts by default. .PP Please note also that the data in the job environment can't be verified by Grid Engine and might therefore contain values which could be misinterpreted in the script environment and cause security issues. .\" .SS "jsv_main()" This function has to be called in the main function in JSV scripts. It implements the JSV protocol and performs the communication with client and server components which might start JSV scripts. .PP This function does not return immediately. It returns only when the "QUIT" command is sent by the client or server component. .PP During the communication with client and server components, this function triggers two callback functions for each job that should be verified. First \fBjsv_on_start\fP() and later on \fBjsv_on_verify\fP(). .PP \fBjsv_on_start\fP() can be used to initialize certain things that might be needed for the verification process. \fBjsv_on_verify\fP() does the verification process itself. .PP The function \fBjsv_send_env\fP() can be called in \fBjsv_on_start\fP() so that the job environment is available in \fBjsv_on_verify\fP(). .PP The following functions can only be used in \fBjsv_on_verify\fP().
