The following codes were run with a limit of 2 hours on the MIPLIB2010 benchmark set with the MIPLIB2010 scripts on two platforms. 1/4 threads: Intel i7-2600, 4 cores, 16GB, 3.4GHz, available memory 12GB 12 threads: Intel Xeon X5680, 12 cores, 32GB, 3.33Ghz, available memory 24GB These are updated and extended versions of the results produced for the MIPLIB2010 paper.

CPLEX-12.6.0: CPLEX
GUROBI-5.6.0 GUROBI
ug[SCIP/cpx/spx]-3.1.0: Parallel development version of SCIP (SCIP+CPLEX/CLP/SOPLEX on 1 thread)
CBC-2.8.10: CBC
XPRESS-7.7.0: XPRESS

Table for single thread, Result files per solver, Log files per solver

Table for 4 threads, Result files per solver, Log files per solver

Table for 12 threads, Result files per solver, Log files per solver

Statistics of the problems can be obtained from the MIPLIB2010 webpage.
