Verification checksum is invalid when compiling with gnu/8.3.1

[koparasy]

Hi, I am compiling XSBench with gcc/8.3.1 the offload version. The compilation finishes with no warnings/errors but when executing the application I am getting the following output:

Simulation complete.

Runtime: 3.067 seconds
Lookups: 17,000,000
Lookups/s: 5,543,286
Verification checksum: 0 (WARNING - INAVALID CHECKSUM!)

The verification checksum is invalid.

Hi @koparasy -- thanks for reaching out! It looks like the validation data is not being transmitted back to the host correctly. There could be a variety of environment issues that may be causing this. Have you been able to successfully run other OpenMP offloading codes on this system with this compiler (e.g., this one?) What sort of GPU are you targeting?
