2013-08-29add erl option to set schedulers by percentagesSteve Vinoski
For applications where measurements show enhanced performance from the use of a non-default number of emulator scheduler threads, having to accurately set the right number of scheduler threads across multiple hosts each with different numbers of logical processors is difficult because the erl +S option requires absolute numbers of scheduler threads and scheduler threads online to be specified. To address this issue, add a +SP option to erl, similar to the existing +S option but allowing the number of scheduler threads and scheduler threads online to be set as percentages of logical processors configured and logical processors available, respectively. For example, "+SP 50:25" sets the number of scheduler threads to 50% of the logical processors configured, and the number of scheduler threads online to 25% of the logical processors available. The +SP option also interacts with any settings specified with the +S option, such that the combination of options "+S 4:4 +SP 50:50" (in either order) results in 2 scheduler threads and 2 scheduler threads online. Add documentation for the +SP option. Add tests for the +SP option to scheduler_SUITE. Add tests and documentation for two existing features of the +S option: +S 0:0 resets the scheduler thread count and scheduler threads online count to their defaults, and specifying negative numbers for +S results in those values being subtracted from the default values for the host.

2013-08-23Create better distribution of files over async threadsPatrik Nyblom
The actual port id is used to create a key from the pointer value which is the ErlDrvPort. To do this a new driver api function driver_async_port_key is added and the driver API minor version is updated. The documentation is updated and the faulty description of how to spread ports over async threads is updated to use the new API. Testcase also added.

Hi Fredrik, > I've gotten some feedback from your review, > You need to add documentation under Erts-> "User's Guide" -> "tty - A > command line interface" > > You need to add testcase in interactive_shell_SUITE a simplified > example of how this testcase could look like; > ctrl_w_and_ctrl_u(_Conf) -> > rtnode([{putline,""}, {putline, "2."}, {getline, "2"}, > {putline,"xxx yy"++[$\^w]++"."}, {getline,"xxx"}, {putline,"xxx > yy"++[$\^u]++"z."}, {getline,"z"}],[]). Please find an updated version of the patch attached to this e-mail. I hope that you still accept it via e-mail because the former patch was sent the same way ;-). I have extended the documentation to list the new key combinations and added tests to make sure they work.

Documentation and tests are extended to reflect the new functionality.

2013-06-11erts: Add the +sfwi system flagRickard Green
+sfwi Interval Set scheduler forced wakeup interval. All run queues will be scanned each Interval milliseconds. While there are sleeping schedulers in the system, one scheduler will be woken for each non-empty run queue found. An Interval of zero disables this feature, which also is the default. This feature has been introduced as a temporary workaround for lengthy executing native code, and native code that do not bump reductions properly in OTP. When these bugs have be fixed the +sfwi flag will be removed.
