Can we run the code with more than 3 processors ? #21

I tried changing the input data by changing the number of processors to 4 and other required changes in the following files: '../test/canonicalgraph_task_exe_time.csv' '../test/canonicalgraph_resource_BW.csv' '../test/canonicalgraph_task_connectivity.csv'

But getting this error: Screenshot 2023-06-08 at 6 30 22 PM

Could you please guide me to resolve this, i need this ASAP to complete my college project.

Awaiting your timely response. Thanks a lot :)

Yeah, the code is scalable for more processors. It would be nice to know which matrix is being indexed out of bounds on that line, but I'm assuming it's the _self.communication_startup matrix (the list of "startup" communication costs).

You can pass that in with the communication_startup argument for heft.schedule_dag. That was added after this jupyter notebook was created via #14 , so it's not specified on that jupyter cell

Is there an update on this issue. Having the same Problem with scaling. Tried to pass the communication_startup as an argument but got an Value Error back. Created the Graphs with the included generator. It looks like more than 4 processors triggers an array out of bounds. EDIT: Found the problem. it really was the communication_startup. I altered the default size and it now works.
