Test_fft_memory.cc
|
||||
|
||||
Memory growth test for PlannedFFT on a spin-colour matrix (propagator) field.
|
||||
|
||||
The test creates a single PlannedFFT object (which allocates FFTW plans once),
|
||||
then repeatedly applies FFT_all_dim to the same propagator 400 times.
|
||||
|
||||
If PlannedFFT is working correctly the RSS should remain flat after the first
|
||||
iteration — no new plans, no new deviceVector allocations beyond the per-call
|
||||
pencil buffer which is freed at the end of each FFT_dim_execute call.
|
||||
|
||||
Build exactly like any other Grid test, e.g.:
|
||||
make Test_fft_memory
|
||||
or compile manually:
|
||||
$(CXX) $(CXXFLAGS) Test_fft_memory.cc -o Test_fft_memory $(LDFLAGS)
