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

Please add your own results.

Benchmark (single core) and scaling results on multiple cores/cpus. cores indicates how many cores are available to the user on this cpu or the maximum number of cores on the node that were used for benchmarking scaling.

(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.

In the table below, # cpus really means how many independent cores are available.
