Memory overutilization error #19

Closed sjoks93 closed 9 months ago

sjoks93 commented 11 months ago

AssertionError: Memory shared by {'I1': 1, 'I2': 1, 'O': 1} (memory operand, memory level) has shared utilization of 1.02569580078125, which is > 1 (memory level starts from 0).

I receive this error when running the temporal search engine using the attached directory and the following command:

python seneca/main.py --model seneca.inputs.workload.resnet_layer1 --accelerator seneca.inputs.hardware.hardware --mapping seneca.inputs.mapping.mapping seneca.zip

Hi. Thanks for spotting this issue. We hadn't considered your architectural case where only a higher memory level is unrolling an irrelevant output dimension ('C' in your case) which requires partial sum precision. I have fixed it in release 2.4.4.
