c - How to force OpenMPI to use GCC instead of ICC? Is recompiling OpenMPI necessary? -

-

I have a C-code for parallel computing written for GCC , and I I want to compile the cluster, which apparently uses mpicc via icc . I also wonder if I'm going to openmpi to use GCC for the time being appropriate for the code to be corrected by the ICC Code> ask instead. I do not have admin rights on that cluster, and I really do not want to mess up the original configuration.

If it is not possible to set it for example Makefile , then I hope that I can compile the openmpi in my home directory, but After this I need some guidance what should be done after that. Can you help me

UPDATE1

Makefile in 

  cc = mpicc CFLAGS + = -DMPI

and here are some openmpi files 

  $ mpicc / usr / bin / mpicc lrwxr-xr-x / usr / bin / mpicc - & Gt; Opal_wrapper -rwxr-xr-x / usr / bin / opal_wrapper

I know, if I can provide you more information.

was able to find the OpenMPI settings for UPDATE2 mpicc 

  $ more / ,   
 usr / local / share / openmpi / mpicc- wrapper- data.txt project = open mpei project_short = ompi version = 1.1.4 language = c compiler_env = cc compiler_flags_env = cflgs compiler = ICC extra_includes = openmpi preprocessor_flags = compiler_flags = -pthread linker_flags = libs = -lmpi -lorte -lopal -ldl -Wl, - export dynamic -lnsl -lutil -ldl required_file =

However, I No rights to edit this file, and the OPMI_CC = GCC compiler does not change is.

Update3

Environment variable cc = gcc does not help 

  $ Cc Export CC = GCC $ countercurrent $ cc gcc $ $ net $ $ make ... ICC: ... errors

UPDATE4

... but expor t OMPI_CC = GCC helps in the end (). I should remember one day that these are different things ...

In spite of this, binary was created, I got the following goodbye message 

  / opt / intel / Fce / 9.1.036 / lib / libimf.so: Warning: Warning: feupdateenv is not implemented and always

See.

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
