tesseract-4 (pdfsandwich) and high load average/CPU load
Hya,
I'd appreciate expert opinion.
System: Core i3 (quad core), debian amd64 buster
While preparing search-able pdf file, with pdfsandwich and tesseract-4, load average goes as high as 16 with all cpu's have 100% load. Only one thread of pdfsandwich.
I know with -nthreads option, I can restrict tesseract threads. But still load average goes insanely high. (8 with two threads, with all 4 CPU's 100% load)
I somewhat worry whether context switch (or whatever) is wasting resources. It is slower than old system (with tesseract-3)
Is there any easy thread/load control? This is a computation node in my cluster, it usually runs headless.
syg00: Thanks, the trick in that link works. (env OMP_THREAD_LIMIT=1) I may need further optimization, but it runs within acceptable time, (20 sec, used to be almost an hour)
