Notes

  • according to Mike's email mesh should be around 100k vertices
  • Metric Input Data available at https://github.com/UGAWG/parallel-adapt-results
  • Input surface is the coase mesh available at https://github.com/UGAWG/solution-adapt-cases
  • The experiments performed on a DELL workstation with Linux Red Hat Enterprise, 24 hardware cores Intel® Xeon® CPU E5-2697v2@2.70 GHz, and 757 GB RAM
  • Memory is measured at the end of Mesh refinement and thus it may reach a slightly higher value before the point of measurement
  • parameters --brec=2 --met=1 --meval=3 --mrecm2=1 --mrec4=1 --nadapt=2 --malign=0 --mpp=2 --ndfs=0 --nthreads=$THREADS --nbuckets=20*$THREADS --nthreadsaf=20*$THREADS --nbucketsaf=20*${THREADS} --blockmul=500000 --nqual=0 --nminpts=30 --ordt=0 --pardeact=1 --mdse=0
