Im looking for information sources on code optimization using
the Intel CPU and the MMX/SSE family instruction set.
From what I have searched this group is the closest group to
the subject of code optimization / vectorization.
Could someone recommend of:
Thanks,

Undoubtedly, vectorization will be crucial to the application of AVX. Your topic is still too broad. You may be interested in compiler auto-vectorization with Fortran (vast on-line resources available) or C (similar, with more requirements, some resources available), or something else. For example, the topic has been discussed frequently on the Intel compiler forum sites.
Im interested in optimization for C++ code. I am using the
Intel 64 and IA-32 Architectures Software Developer's Manuals (5 volumes) for
reference.
What I am looking for is a user group where I can post
general SSE programming questions and see example source code. For example I
want to know if there is a conditional statement equivalent to if/else in SSE,
where I could condition intrinsic operations based on results in the registers.
Thanks,

SSE4 blend instructions implement if/else conditional moves, such as Fortran MERGE. Prior to SSE4, the same operation could be implemented with masks.
