A lot of file opens and closes?

Dear developers,

I am running the standalone I-TASSER v5.1 on a shared computer cluster. I typically request 10 CPUs and a single node, and run the software in the Linux system with the these extra parameters: -homoflag real -light true -runstyle gnuparallel.

I was reported by the administrators that there were 7000 file opens and closes in the span of 10 seconds for the job I submitted. And it seems this consistently happens in all the jobs I submitted for I-TASSER. Is it a typical part of the pipeline?
