CPUTEST
stresscpu2 v1.0.1 (Processor Benchmarks)
This test runs a series of GROMACS inner loops hand coded in assembly for speed and efficiency on SSE units. The short run lengths are only useful for heating up your CPU, for a proper test, use the 6 or 12 hour run length. This test will cause unstable hardware to stop responding and require a hard reboot.
