Hi,
Recently I compile new 2019.2 on the new iMAC with GPU Radeon Pro 555 2GB.
Below is the compilation:
```
curl http://ftp.gromacs.org/pub/gromacs/gromacs-2019.2.tar.gz --output
gromacs-2019.2.tar.gz
tar -xvzf gromacs-2019.2.tar.gz
mkdir ~/gromacs
cd ~/gromacs-2019.2
mkdir build
cd build
~/cmake/bin/cmake ../ -DGMX_MPI=ON -DGMX_GPU=ON -DGMX_CLANG_CUDA=ON
-DGMX_USE_OPENCL=ON -DGMX_FFT_LIBRARY=fftpack -DGMX_SIMD=AVX2_256
-DCMAKE_INSTALL_PREFIX=~/gromacs
make -j 4
make install
```
The same situation for fftw3 compile by GROMACS.
When I run MD with GPU, the simulation is unstable comparing to the normal
all-on-CPU.
I came back to make check to check my compilation, below is output:
```
93% tests passed, 3 tests failed out of 40
Label Time Summary:
GTest = 156.88 sec*proc (40 tests)
IntegrationTest = 60.77 sec*proc (5 tests)
MpiTest = 1.92 sec*proc (3 tests)
SlowTest = 37.90 sec*proc (1 test)
UnitTest = 58.21 sec*proc (34 tests)
Total Test time (real) = 157.81 sec
The following tests FAILED:
29 - GmxPreprocessTests (Timeout)
37 - MdrunTests (Failed)
40 - MdrunMpiTests (Failed)
Errors while running CTest
make[3]: *** [CMakeFiles/run-ctest-nophys] Error 8
make[2]: *** [CMakeFiles/run-ctest-nophys.dir/all] Error 2
make[1]: *** [CMakeFiles/check.dir/rule] Error 2
```
All the failed tests show the error as below:
```
Program: mdrun-mpi-test, version 2019.2
Source file: src/gromacs/ewald/pme-gpu-3dfft-ocl.cpp (line 62)
Function: void handleClfftError(clfftStatus, const char *)
Internal error (bug):
clFFT execution failure: -57

Any suggestion whether this is a bug or something else?
Thank you a lot for consideration.
