You can limit the number of threads alloted for this by setting relevant environment variables (e.g. MKL_NUM_THREADS)or by calling specific functions (e.g. MKL_Set_Num_Threads). Details can be found in MKL User's Guide and MKL Reference Manual. <BR /><BR />Thanks<BR />Dima<BR /> Wed, 09 Sep 2009 08:53:42 GMT Dmitry_B_Intel 2009-09-09T08:53:42Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/how-to-use-parallel-FFT-verison-with-MKL/m-p/875492#M8879 <STRONG>Hi, all,<BR /><BR /> I have a workstation with 24 cores, and Iwant toperformFFT in paralle with MKL.<BR /><BR /> Would anyone like to give me some help on how to do it ? thank you !</STRONG> Wed, 09 Sep 2009 06:36:28 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/how-to-use-parallel-FFT-verison-with-MKL/m-p/875492#M8879 afd_lml 2009-09-09T06:36:28Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/how-to-use-parallel-FFT-verison-with-MKL/m-p/875493#M8880 <DIV style="margin:0px;"> <DIV id="quote_reply" style="width: 100%; margin-top: 5px;"> <DIV style="margin-left:2px;margin-right:2px;">Quoting - <A href="https://community.intel.com/en-us/profile/441618">afd.lml</A></DIV> <DIV style="background-color:#E5E5E5; padding:5px;border: 1px; border-style: inset;margin-left:2px;margin-right:2px;"><EM><STRONG>Hi, all,<BR /><BR /> I have a workstation with 24 cores, and Iwant toperformFFT in paralle with MKL.<BR /><BR /> Would anyone like to give me some help on how to do it ? thank you !</STRONG></EM></DIV> </DIV> </DIV> <BR />Do you want to try the Cluster FFT set of routines or the multi-thread ones?<BR /><BR />I'm in trouble with MKL parallel FFT routines because it seems that they don't work. I have posted yesterday about my problem (with a sample code extracted from the MKL manpages) and I'm waiting an answer. You can start to try with it (if it's work, obviously) ...<BR /><BR />Cheers!<BR /> Wed, 09 Sep 2009 07:56:02 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/how-to-use-parallel-FFT-verison-with-MKL/m-p/875493#M8880 Filippo_Spiga 2009-09-09T07:56:02Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/how-to-use-parallel-FFT-verison-with-MKL/m-p/875494#M8881 <DIV style="margin:0px;"></DIV> <BR />Hi,<BR /><BR />MKL does internal threading of FFTs automatically, where it can.
