While running OpenCL ingest example on two accounts that our company has we have found a difference that breaks execution of this example. I posted all of the details here:
Most likely the difference is environment elated. Please take a look at 2019 account u34222 and make its environment the same as 2020 account u44838 which has run GPU OpenCL example without a problem.
Sorry for the delay.
Since your account which needs to be fixed is very old, the best way to resolve your issue is to apply for a new account and also there are lot of changes in the new devcloud accounts.You can apply for new account here https://intelsoftwaresites.secure.force.com/DevCloud/
