Revision as of 15:57, 14 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.
| vendor | model | GHz | cores | time/min | binary | revision |
|---|---|---|---|---|---|---|
| Intel | Quad Core Xeon L5410 | 2.33 | 4 | 1:27 | hippo | rev32 |
| Intel | Quad Core Xeon L5410 | 2.33 | 4 | 1:31 | hippo_p3 | rev32 |
| Intel | Core Duo T2300 (Mac Mini) | 1.66 | 2 | 2:41 | hippo_p3 | rev32 |
| Intel | Xeon 2.4 | 2.4 | 1 | 3:03 | hippo_p3 | rev26 |
| AMD | Athlon XP 1800+ | 1.53 | 1 | 4:30 | hippo_p3 | rev26 |
(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| hippo\n| ?\n", vendor, model, GHz, cores)}
into the wiki table and replace TIME by what you measured.
