My sony vaio has a processor model: Intel® Core™ i7-3517U It appears to me as being 4 cores but it does not show the threads. What is wrong? How could I fix it? How can I access that information? I just want to check that my 4 x 2 virtual threads are really there working at the fullest! ;)
- OS type: ubuntu 13.10 64-bit
- Processor: Intel® Core™ i7-3517U CPU @ 1.90GHz × 4(cores)
Obs.: The computer came with windows 8, but I do not like windows, then I swap to ubuntu! But it was working with 8 threads before, I checked myself, but in ubuntu I can't find this information.
Any help I will appreciate! Cheers!

I added only information about processor 0, there are 3 more processors but not so different from this one.
