[gem5-users] Running pthread Application Binary on gem5

[Abhishek Singh]

Hello Users,

I am trying to run BWA(https://github.com/lh3/bwa) its an application to
align DNA sequence, one can think of as string matching type of program.

The command line I use is:

*/home/abs218/baseline/gem5/build/X86/gem5.opt
/home/abs218/baseline/gem5/configs/example/se.py -c /home/abs218/bwa/bwa -o
"mem ../genome/test/ref.fa ../genome/test/test_PE1.fa" --caches --l2cache
--l1d_size=32kB --l1i_size=32kB --l2_size=256kB --l1d_assoc=8 --l1i_assoc=8
--l2_assoc=8 --cacheline_size=64 --cpu-type=DerivO3CPU
--mem-type=DDR4_2400_8x8 --mem-size=8GB --sys-clock=2.6GHz
--cpu-clock=2.6GHz -n 8*


I use more than 1 core because the "BWA" application uses pthreads.


The error I encounter is "panic: Tried to read unmapped address
0x8000000000255298."


Is there a way I can overcome the error?

Best regards,

Abhishek

Use full system instead if you don't find a solution, it's more reliable.
