Dear all, I just tried to run Milkyway in the system described in the title line :
Device 'gfx906:sramecc+:xnack-' (Advanced Micro Devices, Inc.:0x1002) (CL_DEVICE_TYPE_GPU)
Board: Vega 20
Driver version:      3241.0 (HSA1.1,LC)
Version:             OpenCL 2.0 
Compute capability:  0.0
Max compute units:   60
Clock frequency:     1725 Mhz
Global mem size:     34342961152
Local mem size:      65536
Max const buf size:  29191516976
Double extension:    cl_khr_fp64
but all I got were signal 11 (segmentation violation) coming from libamdocl64.so. Many other OpenCL applications works without a problem (collatz, primegrid, amicable etc.)

Does anyone have hints or suggestions?
