Hi~ I think i might meet with some wired problem with Intel MKL.
I install visual studio 2013 and intel xe composer 2013 sp1 on two machines, one is pc with windows 8.1 equped with intel core i5-3470 3.2GHZ and the other is server with windows 2008 r2 sp1 and xeon e7330 2.4GHZ.
Then, i ran test program dgemm_threading_effect_example under C:\Program Files (x86)\Intel\Composer XE 2013 SP1\Samples\en_US\mkl\tutorials\mkl_mmx_c(I changed matrix size to 2000*2000*1000)
Under one thread, the running time is 1049 ms for server and 349 ms for PC. Such difference remaines as thread number is increased. I also compared one toolkit with neural network model with same setting and got same results. This really puzzles me as i am trying to run some experiments with MKL on server, which supports more threads.
So can anyone tell me the difference of the performance?
Thanks a lot!
