Open forum for general discussions relating to PLASMA.
I would like to understand this behavior here. I've run time_dgemm and time_dgemm_tile on my machine (Xeon X5650 4CPUx6Cores 48GB ). See the result below
Why is that happening? Any ideas would be much appreciated.

So you probably know that dgemm_tile is faster than dgemm, because it skips the layout translation.
So, your question is about the drop-off when exceeding 12 cores.
The first thing on my mind is a NUMA effect.
Try using numaclt --interleave=all
