missing synchronization when tracing HIP events

jmellorcrummey opened this issue · comments

When the debugger is active, hpctoolkit doesn’t write as much trace data for the HIP MatrixMultiplication example that it does when the debugger is not active. There must be missing synchronization to ensure that all trace data is written before the program exits.

reproducer:

git clone https://github.com/jmellorcrummey/spack-configs/TEST/rocmtest/MatrixMult/MatrixMultiplication

fixed by flushing AMD traces in #486
