Plots¶

Power as a function of the logical core usage¶

mendevi plot '<multithread.db>' -x cores -y power -c '(profile, hostname)' -m encoder

Logical core usage as a function of the provided number of threads¶

mendevi plot '<multithread.db>' -x threads -y cores -wx encoder -wy profile -c effort -m quality -f '"aerial" in name'

Final energy as a function of the provided number of threads¶

mendevi plot '<multithread.db>' -x threads -y energy -wx encoder -wy profile -c effort -m quality -f '"aerial" in name'
