physical processors. If a thread is bound to a processor, it is executed on the same logical
processor during the entire execution.
The
auto parameter specifies that threads automatically bind to processors. You specify this
suboption to enable automatic thread binding on different architectures. When
XLPGASOPTS=bind=auto is specified, the run time allocates program threads to hardware
threads in a way that minimizes the number of threads assigned to any one processor.
The
none parameter specifies that no threads bind to processors. When
XLPGASOPTS=bind=none is in effect, a thread is suspended and wakes up on another

The
