Hi there,

does the use of PURE procedures in an OpenMPparallelizedprogram lead toa measurable benefit in runtime with the latest IVF compiler (or any other compiler for that matter)?

I haven't been able to demonstrate a significant difference. ifort seems to rely on inter-procedural analysis for such optimizations. What was your conclusion?

Thanks Tim - I haven't tried for myself and wanted to see whether the program could benefit if I included/restructered procedures as pure procedures. But unless it does not require extra effort I think I will leave it as it is.

Cheers
