You can use the -D__HPACC_FIXED_REFCNT_MUTEX flag to reduce the amount of space used for string mutexes and thereby increase performance when using either -AA or -AP strings. Instead of having one mutex per string, there will be a fixed array of mutexes shared among all strings. This feature requires C++ runtime version A.05.61 or newer. For additional information refer to the -mt option.

The number of string mutexes defaults to 64 and can be configured by:

export aCC_MUTEX_ARRAY_SIZE=##

You can mix code compiled with and without -D__HPACC_FIXED_REFCNT_MUTEX.
