hyperthreading vs multithreading
I'm porting my app to multithreading (for the multi-core processor).
For the moment I detect the number of core like this :
function NumberOfCPUs: integer;
result := si.dwNumberOfProcessors;
but For Proc with hyperthreading it will detect only one Proc, so I
don't use multithreading.
Would it be interesting to use Multithreading with mono core processor
that do have Hyperthreading also ?
I don't know it hyperthreading is just a marketting term or is there's
really a gain.
Thanks for your help.
