The following commands control er_print display output.
Close any open output file, then open filename for subsequent output. When opening filename, clear any pre-existing content. If you specify a dash (-) instead of filename, output is written to standard output. If you specify two dashes (--) instead of filename, output is written to standard error.
Close any open output file and open filename, preserving any pre-existing content, so that subsequent output is appended to the end of the file. If filename does not exist, the functionality of the appendfile command is the same as for the outfile command.
Limit output to the first n entries of the report; n is an unsigned positive integer.
Specify whether to use the long or the short form of function names (C++ and Java only). If shared_object_name is specified, append the shared-object name to the function name.
Set the mode to one of the following:
For Java experiments, show the Java call stacks for Java threads, and do not show housekeeping threads. The function list includes a function <JVM-System> representing aggregated time from non-Java threads. When the JVM software does not report a Java call stack, time is reported against the function <no Java callstack recorded>.
For OpenMP experiments, show master-thread call stacks and slave thread call stacks reconciled, and add special functions, with the names of form <OMP-*>, when the OpenMP runtime is performing certain operations.
For Java experiments, show the Java call stacks for Java threads when the user’s Java code is being executed, and machine call stacks when JVM code is being executed or when the JVM software does not report a Java call stack. Show the machine call stacks for housekeeping threads.
For OpenMP experiments, show the same information as for user mode.
For Java experiments and OpenMP experiments, show the machine call stacks for all threads.
For all experiments other than Java experiments and OpenMP experiments, all three modes show the same data.
