mpi - Scattering an array of repeated numbers on different processors -


How can I disperse an array of numbers repeatedly on different processors in MPI, to ensure that It does happen that two repetitive numbers are not on the same processor.

For example if I have an array 

  a = [0, 1, 2, 2, 3, 4, 4, 5, 6, 8, 8 , 10, 10, 9, 2, 2]

and I want to redefine it on any processor like the same processor on 4 processor 

  [0 1 2 4] at pd0, [2 3 4 5] at pd1, [2 6 8 10] at pd2, [10 9 8 8] <3>  <3 on pd 3> 
 Any idea how this can be done? thank you in advanced.

You need to use It enables you to split a buffer (array) size of N size M in N * M , where N The number of MPI processes in your execution.

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName ().
