I'm running GeekBench 4.3.4 in macOS 10.14.5 on a MacPro5,1 with an NVIDIA GTX 680 Mac Edition. CPU and Metal benchmarks work fine, but OpenCL seems to stop part-way through and then display a result of 0. If I run GeekBench on the command line with the --compute --verbose options (output attached below), I see the following in the "Depth of Field" test:

[0626/021923:INFO:src/geekbench/workload/compute_workload.cpp(91)] workload 311 tid 0 iteration 19 0.00598987s (2.93 GB/sec) uploading

  Depth of Field                    0          0.00 pixels/sec

Is there something I can do to fix this? Thanks for your help!
