Incomplete CPU usage in Ilastik


I am batch processing in Ilastik (version 1.3.3.post2) and my CPU is not used completely. I have trained a couple of 3D stacks with autocontext and want to batch the rest of my files now. I am exporting to hdf5. Somehow, CPU usage stays around 20% and sometimes spikes to 40% before it goes down to 20% again.

I am running this in Ilastik 1.3.3.post2 on a Windows machine with Windows 10, 64GB RAM and Intel® Xeon® Silver 4110 CPU @ 2.10GHz, 2095 Mhz, 8 Core(s), 16 Logical Processer(s).

Are there known issues or a way to maximize CPU to 100% to speed things up?


Hi @Sreusch,

if I only could get my hands on a beefy windows machine… In any case. Have you set the LAZYFLOW_THREADS environment variable as described in our docs? That could give you a little push.

Are your input files hdf5 as well?

Otherwise it would be get to get more accurate statistics on the CPU utilization for the process… On linux there is the time command. But it seems there is no proper replacement for this on windows, afaik.
