Error with USM vector-add example on FPGA

I am trying to follow the oneAPI example on the "hello world"-like vector-add example. Running "make hw -f Makefile.fpga" and "make run_hw -f Makefile.fpga" works fine. However, when I switch to the USM code using "make hw_usm -f Makefile.fpga/ make run_hw_usm -f Makefile.fpga", I get an error. The build appears fine, but the run returns with "Shared memory allocation failure".

Any thoughts as to what is failing? Are there log files that I should be looking at to get more details on the error?
