Only process number 1 has the actual underlying file handle. Therefore all
other workers, when trying to read, report that the file is unaccessible.
You could try to designate one worker for the reads, i.e. use something along
the lines of
@fetchfrom 1 dset=fid["punkty"*string(i)]
You could alternatively try to open the file on all workers - which should be
ok if all accesses are read only.
