What SAP Said About Parallel Processing Working in SNP
For years SAP included a parallel processing field in the SNP optimizer, giving the impression that one could choose how many processors to address in the optimization.
The Truth About Parallel Processing Working in SNP?
After roughly 5 years using the parallel processing setting in SNP, we decided to test the performance of the optimizer with using one processor versus using multiple processors. What we found was there was no difference in the runtime! We covered this in detail in the article How the Parallel Processing Function for the SNP Cost Optimizer Does not Work.
“This is amazing that SAP has had this setting available on the optimizer profile and that the parallelization functionality has either never worked correctly or at some point stopped working properly back in 2003, at least the OSS notes go back to 2003. Secondly, as I am running into problems with it documented as not working in 2013, this means that SAP has not fixed the problem in a decade. I wonder if parallelization has been removed from SAP’s sales presentations on the SNP optimizer. I can’t say for sure – but I have a feeling SAP salesmen have not been telling potential customers that parallel processing is broken.”
The issue is that parallelization of problems is tricky, so SAP simply gave up…..but they never removed the field, giving SAP configurators and testers the impression that it worked.
Conclusion and Calculation
SAP receives a 0% accuracy rating for parallel processing in SNP working.
