Hello, I want to learn about hashing and parallel processing in SAS. Somehow I am not getting any proper documentation where I can get all information and some practice question. can someone please help.
Thanks a ton!
For Hashing - I'm guessing you mean "using hash tables" - go to www.lexjansen.com and search for articles by Paul Dorfman ( @hashman ) or Don Henderson ( @DonH ) or them both, e.g.:
https://www.lexjansen.com/cgi-bin/xsl_transform.php?x=ad&c=SUGI#paulfman
https://www.lexjansen.com/cgi-bin/xsl_transform.php?x=ah&c=SUGI#donhrson
For Parallel - if you think about parallel processing in Base SAS - I did this "almost tutorial" of using "XCMD & systask" for parallel processing, you could try to play with it: https://pages.mini.pw.edu.pl/~jablonskib/SASpublic/Parallel-processing-in-BASE-SAS.sas

Barteku, wielkie dzięki za plug. Also, the uniform splitting into key-exclusive segments (applicable to any data processing) can also be used to create a bunch of parallel jobs to be processed by your xcmd and systask.
OTOH, the question might be about whether or how the hash object works with multithreading, in which case methinks DS2 would be the right direction to look at since it allows hash processing to be multithreaded.
Pozdrowienia,
Paul Dorfman
Pavle,
it may be DS2 or maybe it's about that "parallel datastep" in SAS Vyia?
Pozdrowienia

Had you not told me, I wouldn't know.
Odpowiednio, dziękuję bardzo!
