Supporting Operating Systems
Solaris has implemented a separate LWP layer since version 2.2. Prior to version 9, Solaris allowed a many-to-many mapping between LWPs and user threads. However, this was retired due to the complexities it introduced and performance improvements to the kernel scheduler.
UNIX System V and its modern derivatives IRIX, SCO OpenServer, HP-UX and IBM AIX allow a many-to-many mapping between user threads and LWPs.

Famous quotes containing the words supporting, operating and/or systems:
“I hope you will be benefitted by your churchgoing. Where the habit does not Christianize, it generally civilizes. That is reason enough for supporting churches, if there were no higher.”
—Rutherford Birchard Hayes (1822–1893)
“Many people operate under the assumption that since parenting is a natural adult function, we should instinctively know how to do it—and do it well. The truth is, effective parenting requires study and practice like any other skilled profession. Who would even consider turning an untrained surgeon loose in an operating room? Yet we “operate” on our children every day.”
—Louise Hart (20th century)
“What avails it that you are a Christian, if you are not purer than the heathen, if you deny yourself no more, if you are not more religious? I know of many systems of religion esteemed heathenish whose precepts fill the reader with shame, and provoke him to new endeavors, though it be to the performance of rites merely.”
—Henry David Thoreau (1817–1862)
