2013-11-05Replace the +MMscmgc switch with +MMscrfsdRickard Green
Replaced the +MMscmgc switch with the +MMscrfsd switch. The old switch didn't reflect what it controlled.
2013-11-05Add switch for disabling sys_alloc carriersRickard Green
The switch "+Musac <boolean>" controls if sys_alloc carriers are allowed.
2013-11-05Add support for locking mappings to physical memoryRickard Green
Using "+Mlpm all" switch all mappings made by the emulator will be locked into physical memory.

2013-09-19Teach erlc to handle UTF-8 file namesBjörn Gustavsson
The 'erlc' program passes options to the 'erl' program using the '-s' option. The '-s' option causes all options to be converted to atoms, which implies that UTF-8 file names may not be given on the command line. We could solve just the UTF-8 problem by using '-run' and change the erl_compile module to expect strings instead of atoms, but since that is an incompatible change, we should take the opportunity to make more incompatible changes while we are at it. Specifically, when 'erlc' was first written, there was no way to pass command line arguments starting with '-' to Erlang, so 'erlc' did all parsing of arguments and translated options to atoms starting with a '@' character (for example, -I was translated to @i). Since then, the '-extra' option has been introduced which allows us to pass anything to Erlang at the end of the command line. Therefore, while at it, do the minimum of necessary command line parsing in the 'erlc' program (e.g. the '-smp' option), passing the command line essentially unchanged to 'erl' using the '-extra' option, and rewrite the option parsing in Erlang.

* maint: add erl option to set schedulers by percentages
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.

* maint: erts: Add the +sfwi system flag
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.

2013-01-08escript to accept emulator arguments when script file has no shebangMagnus Henoch
According to the documentation, if the second or third line in a script starts with %%!, then escript will use the rest of the line as emulator options. However, previously this was only the case if the first line started with #!. This change removes that check, and unconditionally uses the %%! line if present.

2012-10-16erts: Change ERL_CRASH_DUMP_SECONDS behaviourBjörn-Egil Dahlberg
Not setting ERL_CRASH_DUMP_SECONDS will now terminate beam immediately on a crash without writing a crash dump file. Setting ERL_CRASH_DUMP_SECONDS to 0 will also terminate beam immediately on a crash without writing a crash dump file, i.e. same as not setting ERL_CRASH_DUMP_SECONDS environment variable. Setting ERL_CRASH_DUMP_SECONDS to a negative value will let the beam wait indefinitely on the crash dump file being written. Setting ERL_CRASH_DUMP_SECONDS to a positive value will let the beam wait that many seconds on the crash dump file being written. A positive value will set both an alarm in beam AND a heart timeout for restart if heart is running. This is due to the change of 'heart' behavior when 'heart' is listening for a crash.
