Merge pull request #68 from ademeure/flush_l2_pr 
Correctly flush L2 (+performance impact & upcoming optimization fork)
 2025-03-16 09:16:34 +08:00
ademeure
6cbff5778f Correctly flush L2, as reconstructing the tensors on every iteration effectively put them in the L2, and gave the GPU enough idle time to avoid thermal throttling in a potentially unrealistic way. 
The previous behaviour is potentially representative of some use cases (e.g. previous kernel filling L2 with the data in a very specific way) but not standard benchmarking practice.
