Performance

Single processor performance

As a basic performance test we run the simulations in the test directory with these commands (on Linux):

cd testjobs
time ./calc_testjobs

• We report the user time.
• CPU properties are found with

  cat /proc/cpuinfo

  and model names from List of Intelmicroprocessors for Intel (also see the detailed lists of Intel x86 CPUs) and List of AMD microprocessors for AMD cpus (also see the detailed lists of AMD CPUs).
• Also report the binary used (hippo or hippo_p3) and the revision.
• Note that these tests only utilize a single core.
• These results only give a rough idea of the relative performance of different architectures.

Please add your own results.

(You don't have to link to the CPU wikipedia page; just put down whatever you got and even if you're unsure. If in doubt just put the output from

cat /proc/cpuinfo | \
  awk 'BEGIN {FS=":"}; \
      /vendor_id/ {vendor=$2}; \
      /model name/ {model=$2}; \
      /cpu MHz/ {GHz=$2/1000}; \
      /siblings/ {cores=$2}; \
      END {printf("|-\n| %s\n| %s\n| %.1f\n| %d\n| TIME\n| ?\n| ?\n", vendor, model, GHz, cores)}'

into the wiki table and replace TIME by what you measured.

Scaling

All tests were run with Hippo beta rev35 on empty systems. See remarks on the test methodology.
