FEM

To Do List

successfull login to hosts skylakesp2 and naples and first run of likwid-bench
In core performance model for vector triad
Measuremtn of vector triad on Emmy (checked the performance model)
OpenMP parallelization of vector triad on Emmy
Scripts for running and plotting created
Created Latex slides template

for skylake/epyc execution:
- ssh testfront - pbsnodes -a - qsub -I -l nodes=skylakesp2:noturbo,walltime=00:10:00
skylake set frequency:
- module load likwid
- likwid-setFrequencies -l for a list of possible frequencies
- likwid-setFrequencies -p for a list of all core and uncore frequencies
- likwid-setFrequencies -f 2.4 set all cores to 2.4 GHz
- likwid-setFrequencies --umin 2.4 set uncore min frequency to 2.4 (same as max uncore frequ)
- likwid-pin -s 0x0 -c E:N:1:1:2 ./triad 900 pin thread to first core
to use likwid perfctr:
- module load likwid
- likwid-perfctr -C S0:1 -s 0x0 -g L3 -O -m ./read <elements> <allig> <num reads> to do measurements in L3 for example, thread pinned to second core on Socket 0 and skip shepard thread (0x0)
- qsub -l nodes=X:ppn=40:likwid -l walltime=XX:XX:XX <batch-script> you have to set the property likwid when requesting a job
