15.0 vs 17.0

[CPati2]

Hi All,

Why is the documentation of 15.0 version more detailed than 17.0? 17.0 doesn't even reference OpenMP on Xeon Phi as 15.0 does?

15.0: https://software.intel.com/en-us/compiler_15.0_ug_c
17.0: https://software.intel.com/en-us/intel-cplusplus-compiler-17.0-user-and-reference-guide

Also, I am on 17.x version and compiling using DeepBench [1] with KMP_PLACE_THREADS flag is working, then why 17.0 says it's depreciated? How to verify this?

icc --version
icc (ICC) 17.0.1 20161005

hello

"OpenMP* Considerations" section for "Programming for Intel® MIC Architecture" in 15.0 https://software.intel.com/en-us/node/522515 
"OpenMP* Considerations" section for "Programming for Intel® MIC Architecture" in 17.0 https://software.intel.com/en-us/node/684404

"Deprecated" word means that the feature still works but might be removed in the future releases.

hope, this helps,

Hi Vladimir,

Thank you. Is core and fine, the only two types of granularity KMP_AFFINITY supports? I haven't found pages where I can see types of argument an environment variable supports and technical meaning of it.

For example: Here [1], I can find details on KMP_AFFINITY, but not on technical details about the arguments this environment variable supports. Few of them are easy to understand, but some like "respect" are not.

KMP_AFFINITY article is described in the  "Thread Affinity Interface" chapter in the 17.0 documentation https://software.intel.com/en-us/node/684320.

I see there values and explanations with pictures
