Hi Niloofar,
I suspect the num-l2caches does not have any effect. Check the system diagram
in m5out/config.dot.pdf and make sure it looks as you expect.
If there is only a single L2 I see how there might be issues for this cache to
get rid of the responses. The panic is essentially because the port itself has
now become a significant buffer (which it never should be).
As a side not, I think the num_dirs only applies to Ruby.

Subject: [gem5-users] running Gem5 on 64 cores in cpu detailed mode for dedup
benchmark
Hi,
I am trying to run gem5 on dedup benchmar for 64 cores and it will give me the
following error:
Global frequency set at 1000000000000 ticks per second
info: kernel located at:
/net/grads/nhezarja/Desktop/m5_system_2.0b3/binaries/vmlinux
warn: Sockets disabled, not accepting terminal connections
0: system.tsunami.io.rtc: Real-time clock set to Thu Jan 1 00:00:00 2009
warn: Sockets disabled, not accepting gdb connections
**** REAL SIMULATION ****
info: Entering event queue @ 0. Starting simulation...
panic: Packet queue system.l2.cpu_side-CpuSidePort has grown beyond 100 packets
@ cycle 160000
[schedSendTiming:build/ALPHA/mem/packet_queue.cc, line 120]
Memory Usage: 974404 KBytes
Program aborted at cycle 160000
Abort (core dumped)
I used this command:
./build/ALPHA/gem5.opt configs/example/fs.py -n 64 --caches --l2cache
--num-l2cache=64 --l1d_size=32kB --l1i_size=32kB --l2_size=64MB --num-dirs=64
--cpu-type detailed --script=configs/boot/dedup_64c_simmedium.rcS
I can run it for 16 cores but I have problem for 64. It is giving me the same
error even for fft.
I increased size of memory in benchmark.py still same error.
any thoughts on this?
Thanks in advance,
Niloofar
