https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Performace-of-distributed-memory-FFTs/m-p/925240#M13324 Hi,<BR /><BR /><BR /><BR /><BR /><BR />Are there any published benchmarks for the distributed memory versions of the MKL FFT functions? I am trying to run an in-place FFT2 on a moderately large problem, but my machine (with 16 MPI processes) essentially grids to a halt; the MPI version of FFTW2 seems to work fine on this problem.<BR /><BR /><BR /><BR /><BR /><BR /><BR /><BR /><BR />The example I was attempting to run is attached; the machine on which I was trying to run this is a 32-processor SGI Altix with 64 GB of RAM with the Message Passing Toolkit from SGI. Thanks in advance.
