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.

2013-08-27tools:Fredrik Gustafsson
In Emacs it is possible to remotely edit a file, by opening for example /ssh:somehost.com:/path/to/file.erl. In Emacs, the feature that makes this possible, is called TRAMP. When compiling such a file, by typing C-c C-k, an inferior Erlang shell is opened on the remote host, but the compilation expression that was evaluated in the remote Erlang shell was: c("/ssh:somehost.com:/path/to/file", [...]). which resulted in a "no such file or directory" error. This commit changes the compilation expression into: c("/path/to/file", [...]). for files opened remotely via TRAMP. The file name is adjusted similarly when compiling .yrl and .xrl files. In a buffer opened remotely, the Elisp function buffer-file-name returns the full path with TRAMP syntax. In this example it would be "/ssh:somehost.com:/path/to/file.erl". A new function, erlang-local-buffer-file-name, has been introduced, which peels off the TRAMP syntax on remotely opened files, while for locally opened files, it just calls buffer-file-name.

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.
