OMP_SCHEDULE |
If the schedule type
specified for the OMP_SCHEDULE is not one of the valid types ( static, dynamic,
guided, or auto), then the environment variable will be ignored, and the default
schedule ( static with no chunk size) will be used. A warning message
will be issued if SUNW_MP_WARN is set to TRUE or a callback
function is registered by a call to sunw_mp_register_warn(). If the schedule type
specified for the OMP_SCHEDULE environment variable is static, dynamic, or guided, but the chunk
specified size is a negative integer, then the chunk size used will be
as follows: For static, there will be no chunk size . For dynamic
and guided, the chunk size will be 1. A warning message will
be issued if SUNW_MP_WARN is set to TRUE or a callback function is
registered by a call to sunw_mp_register_warn(). |
OMP_NUM_THREADS |
If the value of the variable is
not a positive integer, then the environment variable will be ignored and a
warning message will be issued if SUNW_MP_WARN is set to TRUE or
a callback function is registered by a call to sunw_mp_register_warn(). If the
value of the variable is greater than the number of threads the implementation
can support, the following actions are taken: - if dynamic adjustment
of the number of threads is enabled, then the number of threads will
be reduced and a warning message will be issued if SUNW_MP_WARN is set
to TRUE or a callback function is registered by a call to sunw_mp_register_warn().
- if, on the other hand, dynamic adjustment of the number of
threads is disabled, then an error message will be issued and the
program will stop. |
OMP_DYNAMIC |
If the value specified for OMP_DYNAMIC is neither TRUE nor
FALSE, then the value will be ignored, and the default value TRUE will
be used. A warning message will be issued if SUNW_MP_WARN is set to
TRUE or a callback function is registered by a call to sunw_mp_register_warn(). |
OMP_NESTED |
If the
value specified for OMP_NESTED is neither TRUE nor FALSE, then the value
will be ignored, and the default value FALSE will be used. A warning
message will be issued if SUNW_MP_WARN is set to TRUE or a callback function
is registered by a call to sunw_mp_register_warn(). |
OMP_STACKSIZE |
If the value given for OMP_STACKSIZE
does not conform to the specified format, then the value will be ignored,
and the default value (4 Megabytes for 32-bit applications, and 8 Megabytes for
64-bit applications) will be used. A warning message will be issued if
SUNW_MP_WARN is set to TRUE or a callback function is registered by a
call to sunw_mp_register_warn(). |
OMP_WAIT_POLICY |
The ACTIVE behavior for a thread is spin. The PASSIVE behavior for
a thread is sleep, after possibly spinning for a while. |
OMP_MAX_ACTIVE_LEVELS |
If the value specified
for OMP_MAX_ACTIVE_LEVELS is not a nonnegative integer, then the value will be ignored,
and the default value (4) will be used. A warning message will
be issued if SUNW_MP_WARN is set to TRUE or a callback function
is registered by a call to sunw_mp_register_warn(). |
OMP_THREAD_LIMIT |
If the value specified for OMP_THREAD_LIMIT is not
a positive integer, then the value will be ignored, and the default
value (1024) will be used. A warning message will be issued if
SUNW_MP_WARN is set to TRUE or a callback function is registered by a
call to sunw_mp_register_warn(). |
