Hi,
I installed "parallel_studio_xe_2015_update3".
I ran the command:
perl build.pl --cmake=speech-codecs,intel64,make,d,mt,debug --build --clean
(I know speech codecs is no more supported, but my query is not about that..)
By default the build happens with gcc.
Query 1> Why gcc is default? Why not icc? Why icc location is not set in the $PATH? (Is it because I've installed parallel_studio_xe_2016 also? or it depends on type of license I've)
Query 2> When icc was forced to compiler, build failed. Why?
Query 3> The command "icc -fopenmp openmp2.c" (see attached code) gives correct multithread output (see below). Whereas, same code in IPP framework (i.e., when put in player.c of speech-codec) gives single threaded output. Why? How to get multithreaded output? Any code snippet similar to attached one, that demonstrates IPP multithread features?
Query 4> Does icc perform better than gcc? (What is the meaning it is gcc compatible - icc version 15.0.3 (gcc version 4.8.3 compatibility)?)
(I've Xeon D1540 board.)
correct multithread output:
1
4
1
3
1
single threaded output:
1
1
1
1

Thank you,
