@Gaetano: Thank you for the comments. I'll change accordingly and post it back. I am using T because, the code need to run double precision float also. @Joel: The Boost.SIMD is generalized. Designing algorithms specific to uBLAS increases the performance. Odeint have their own simd backend.

odeint has no simd backend, At least i am not aware of an simd backend. Having one would be really great.

Hi, i have developed vector addition algorithm which exploits the hardware parallelism (SSE implementation).

A few comments:

- That is not C++ but just C in disguise of C++ code . SSE1 CTOR doesn't use initialization list . SSE1 doesn't have a DTOR and the user has to explicit call the Free method

- const-correctness is not in place - The SSE namespace should have been put in a "detail" namespace - Use memcpy instead of explicit for - Why is SSE1 template when it works only when T is a single-precision, floating-point value ?

Also I believe a nice interface whould have been:

SSE1::vector A(1024); SSE1::vector B(1024); SSE1::vector C(1024);

C = A + B;
