* Report Out from uDAPL BTL

*
|
|
* - BTL_ERROR() : Use to report out errors from uDAPL BTL. These are
|
|
* critical errors which will most likely cause the program to fail so
|
|
* this message should always be reported to the user. Defined in
|
|
* btl/base/btl_base_error.h.
|
|
* Example:
|
|
* dat_strerror(rc, (const char**)&major, (const char**)&minor);
|
|
* BTL_ERROR(("ERROR: %s %s %s\n", "dat_cr_accept", major, minor));
|
|
*
|
|
* - BTL_UDAPL_VERBOSE_OUTPUT() : Use to output different levels
|
|
* of verbosity to the user. See Note below.
|
|
* Example:
|
|
* BTL_UDAPL_VERBOSE_OUTPUT(VERBOSE_DIAGNOSE,
|
|
* ("WARNING: don't %s", "jump"));
|
|
*
|
|
* - BTL_UDAPL_VERBOSE_HELP() : Use output information as defined in
|
|
* uDAPL BTL help file (help-mpi-btl-udapl.txt). See Note below.
|
|
* Example:
|
|
* BTL_UDAPL_VERBOSE_HELP(VERBOSE_SHOW_HELP,
|
|
* ("help-mpi-btl-udapl.txt",
|
|
* "invalid num rdma segments", true, 22));
|
|
*
|
|
* Note : - Verbose levels are defined below. These levels are
|
|
* controlled by the mca parameter "btl_udapl_verbose".
|
|
* The verbose level is set to 10 by default so that critical
|
|
* error and useful help information will appear. Which ever value
|
|
* this param is set to, those messages as well as any lower level
|
|
* verbose messages will be reported.
|
|
* - Setting "btl_udapl_verbose" to "-1" will turn off all
|
|
* messages reported by the use of BTL_UDAPL_VERBOSE_*().
|
|
* - These macros should not be used in a critical path as they
|
|
* are always included in the compiled code.
|
|
* - These macros rely on the use of paranthesis around the "args"
|
|
* value.
|
|
*
|
|
* Values used with BTL_UDAPL_VERBOSE_*():
|
|
*
|
|
* - 0: critical user information; should always be reported;
|
|
* on by default
|
|
* - 10: useful help messages that would be reported from
|
|
* "help-mpi-btl-udapl.txt"; accessed from
|
|
* BTL_UDAPL_VERBOSE_HELP(); on by default
|
|
* - 20: general execution diagnostic information;
|
|
* may be useful to user or btl developer
|
|
* - 30: basic debugging/diagnostic information
|
|
* - 90: useful only to developers
|
|
* - 100: other components do not appear to go beyond 100 for verbose
|
|
* levels so noting here as the max for future reference
