[gem5-users] Re: Running Garnet for a large number of nodes

[Krishna, Tushar via gem5-users]

Are you interested in just running garnet in a standalone manner? I had created 
a patch to address this issue that I can share. If you want to run full system 
simulations though, I am not sure if we can simulate more than 64 cores,

Best,

Hi All,

I want to simulate a topology in Garnet with a large number of nodes (e.g. 256 
to 1024). However, for a large number of nodes like 512 nodes, I get this error:

Did you forget to `#include <pybind11/stl.h>`? Or <pybind11/complex.h>,
<pybind11/functional.h>, <pybind11/chrono.h>, etc. Some automatic
conversions are optional and require extra headers to be included
when compiling your pybind11 module.




Does anybody have an idea how I can solve this problem?

Thanks,
