task_switch -- Task switch overhead benchmark
 Recommended:
   task_switch -11 -p:size 2048 -steady 10 -lat -show_loop -ms 200

 Sweeping pulse size:
   -1 -- Alternate Fftm/vmmul kernels
   -2 -- Alternate */+ kernels

 Parameters (for sweeping convolution size, cases 1 through 10)
  -p:rows ROWS -- set number of pulses (default 64)

 Sweeping number of pulses:
  -11 -- Alternate Fftm/vmmul kernels
  -12 -- Alternate */+ kernels

 Parameters (for sweeping number of convolutions, cases 11 through 20)
  -p:size SIZE -- size of pulse (default 2048)

 Common Parameters
  -p:check {0,n}|{1,y} -- check results (default 'y')
