Hi all,
I am trying to simulate PageRank in full system simulation. The application
generates a kronecker graph at the beginning (e.g. ./pr -g 10 generates a
kronecker graph witih 1024 nodes). The problem is that when I try to
simulate the whole application with KVM, I get the correct result but when
I switch to a detailed cpu (atomic, o3 or timing) just before the
application starts, it cannot generate the graph properly.
def writeBenchScript():
file_name = '/home/muhammet/Desktop/run_pr'
with open(file_name,"w") as bench_file:
bench_file.write('m5 exit\n')
bench_file.write('/home/gem5/gapbs/pr -g 4 \n')
bench_file.write('sleep 30 \n') # to print to console.
return file_name
The code above creates the script.I am using this
<https://github.com/darchr/gem5art/blob/master/docs/disks/npb/runscript.sh>
runscript to send the file create above to the guest and my run config file
is like this:
boot_linux()
m5.stats.reset()
if not cpu_name == "kvm":
system.switchCpus(system.cpu, system.detailed_cpu)
run_gap_benchmark()
m5.stats.dump()
finish_the_rest
What I normally should get is something like this:
Generate Time: 0.00023
Build Time: 0.00016
Graph has 16 nodes and 67 undirected edges for degree: 4
But I am getting:
Generate Time: 0.00000
Build Time: 0.00000
Graph has 14 nodes and 0 undirected edges for degree: 0
What is the problem that I am missing?
Best,
Muhammet
