Model:cluster v.1 (CTMC)
Parameter(s)N = 128, T = 2000, t = 20
Property:qos1 (prob-reach-time-bounded)
Invocation (default)
perl ./convert.pl cluster.props label qos1 T 2000
./stamina/stamina/bin/stamina cluster.prism newcluster.props -kappa 1e-9 -const N=128,T=2000,t=20
Execution
Walltime:215.83099675178528s
Return code:0, 0
Note(s):The tool result '5498880147078249/4611686018427387904' is tagged as incorrect. The reference result is 'OrderedDict([('lower', 0.001072402434), ('upper', 0.001072402634)])' (approx. OrderedDict([('lower', 0.001072402434), ('upper', 0.001072402634)])) which means a relative error of '0.1118767546219302' which is larger than the goal precision '0.001'.
