As u know gnuradio have problem with threading especially with Xeon cpu.

Somebody advise me by using Intel Parallel Studio , we can optimize threading in Linux , therefore in gnuradio

My purpose of using Intel Parallel Studio is optimizing threading in gnuradio with Xeon cpu

Gnu Radio has no problem with *threading*, since each block runs in its own thread.   What IS true is that GCC doesn't always recognize
  opportunities to exploit SIMD instructions as well as other compilers.

The VOLK library exists to allow blocks to *explicitly* take advantage of parallelism opportunities with whatever SIMD instructions the hardware
  is capable of, and many of the core blocks in Gnu Radio already take advantage of VOLK.

My suspicion is that the gains you'll get from a compiler that is better able to recognize opportunities for parallelism that GCC will be modest at best.

GNU Radio is typically built using GCC or Clang on Linux platforms, on
Mac OS X it's most commonly built using Clang, on Windows using
Microsoft Visual C++, I've done a MinGW64 build, too.

I don't really think that answers the underlying question: *Why* is
this of relevance to you? When you tell us your motivation for
questions, you'll get better answers.
