Dear Nilay
Sure. But, arguments? what arguments?
You mean the arguments for execution like
"./build/ALPHA_SE/gem5.debug configs/spec2006/spec2006_se.py -n 16 --bench
test -t --l1i_size=32kB --l1d_size=32kB --l2_size=16MB --num-l2caches=16
--topology=Mesh --num-dirs=16 -I 2000000 --ruby --garnet-network=fixed
--mesh-rows=4"
??
or
You mean
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff643ed30 in memcpy () from /lib/libc.so.6

vi build/ALPHA_SE/mem/ruby/common/DataBlock.cc:95
95 : memcpy(m_data, obj.m_data, RubySystem::getBlockSizeBytes());
Anyway, Now, I compiled debug mode.
If I used 15GB memory, it works well,
but if I used 16GB memory, it doesn't work and show segfault
Help me, please

Can you compile gem5.debug and provide the arguments that cause memcpy() to
result in a segmentation fault?
