Hi All,
I've also tried to modify src/mem/Bridge.py from
req_size_a = Param.Int(16, "The number of requests to buffer")
req_size_b = Param.Int(16, "The number of requests to buffer")
resp_size_a = Param.Int(16, "The number of requests to buffer")
resp_size_b = Param.Int(16, "The number of requests to buffer")
to
req_size_a = Param.Int(64, "The number of requests to buffer")
req_size_b = Param.Int(64, "The number of requests to buffer")
resp_size_a = Param.Int(64, "The number of requests to buffer")
resp_size_b = Param.Int(64, "The number of requests to buffer")
but it still gives me the same error. Since I am not familiar with buses and
bridges, please help me. Thanks!
Best Regards,
Teng Lu

Subject: [gem5-users] How to increase the bridge buffer?
Hi all,
When I simulate 64 core system, a panic comes out:
panic: Need to implement cache resending nacked packets!
@ cycle 200215000
[recvTiming:build/ALPHA_FS/mem/cache/cache_impl.hh, line 1638]
Memory Usage: 861708 KBytes
Program aborted at cycle 200215000
Aborted
Based on previous threads such as
http://www.mail-archive.com/[email protected]/msg01370.html and
http://www.mail-archive.com/[email protected]/msg02117.html, this prolem is
caused because the bridge buffer size is not large enough. However, I didn't
find any code in src/mem/bridge.hh or src/mem/bridge.cc regarding buffer size.
Could anybody tell me how to increase the buffer size? Thanks a lot!
Best Regards,
Teng Lu
