Machine Specifications

The competition will run on the StarExec cluster of machines at the University of Iowa.

The machines have these specifications:

# Starexec stats nodes 0 - 32:
Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz (2393 MHZ)
    10240  KB Cache
    129022 MB main memory

# Starexec stats nodes 33 - 192:
Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz (2393 MHZ)
    10240  KB Cache
    258294 MB main memory

# Software:
OS:     Red Hat Enterprise Linux Server release 7.2 (Maipo)
kernel: 3.10.0-327.10.1.el7.x86_64
glibc:  gcc-4.8.5-4.el7.x86_64
        glibc-2.17-106.el7_2.4.i686

A StarExec virtual machine image is available here.

The machines have 2 processors each and 4 cores per processor. For the competition, two job-pairs will be run on a given machine at a given time (one on each processor, with 4 cores available), and the available memory will be capped at 61440 MB.

We reserve the right to make software and configuration changes before the competition. Please exercise your solver(s) on a few benchmarks to ensure that they run successfully!
