Dear Nata,
Can you send me your script? Further, I would like to tell you my problem that is, I am currently trying to read a bunch of *.sdf files from IDL and then doing post-processing. The problem is since the data size is huge, my IDL script is taking an enormous time.

Hence, can you kindly advise me as of how should I write a parallel IDL script which can read the file in parallel mode and finishes quickly?
Thanking you in advance!

Looking forward to a positive for a positive responce.
