hipe

I'm a beginner with rebar and erlang generally. I was trying to create an erlang release with rebar according to this tutorial: http://www.metabrew.com/article/erlang-rebar-tutorial-generating-releases-upgrades and got stuck at the point of running generated release. My system is Ubuntu 11.04 64bit, erlang R14B03, installed from sources. When i'm invoking 'bin/somenode console', I get one of the following errors: Exec: /home/ghik/Inz/somerel/rel/somenode/erts-5.8.4/bin/erlexec -boot /home/ghik/Inz/somerel/rel/somenode/releases/1/somenode -mode embedded -config /home/ghik/Inz/somerel/rel

Is it possible to have a VM instance that executes both HiPE code and the usual "opcode" based objects at the same time? This question is related to : Erlang OTP release compiles with HiPE? Yes, that is how the native compiler is integrated. Only those modules that are compiled with the +native option are executing in native machine code, and the rest are interpreted by the BEAM emulator as usual. When you make calls between modules compiled in different ways, a "mode switch" happens. This way, you can mix native and emulated modules seamlessly. Still, you should try to select which modules

What are the limitations/constraints when compiling Erlang .erl source with the +native option compared with the usual "non native" compilation? Related to: Erlang OTP release compiles with HiPE? The functionality for tracing, breakpoints and single stepping that the BEAM emulator provides are not available in native compiled code. There is also still a limitation that native code is not really unloaded from memory when you load newer versions of the same module. (This can be an issue if you have a long-running system where you keep upgrading modules or generate and compile modules dynamically

After reading this question Is Erlang the C of the clustered computing world? , I am wondering the official Erlang OTP compiles with HiPE? In other words, when I compile my .erl source with the OTP release R13 (as example), does it produce "object code" BEAM? Looking at http://www.it.uu.se/research/group/hipe/ , it does not appear that a standalone HiPE compiler is maintained anymore. gleber By default HiPE is not used to compile OTP. It is known, however, that OTP libraries can be successfully compiled using HiPE with usually some performance boost (though it depends on your application).
