Hello,

I am trying to run NFFT inside parallel MP process. It runs very slow compared to serial mode. I wonder if there is somewhere default parallel option on in NFFT which I suppose to turn off to make it run faster in parallel processing. Thanks

AFAIK, the NFFT library does not expose any means for controlling the level of parallelization used for computation. You may try to either compile NFFT without OpenMP support, if at all possible, or find whether there is some environment variable that you could set to control the number of cores used by OpenMP.
