Revision as of 14:51, 21 November 2008
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_Intel_microprocessors 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.
