Problem Note 61839: You might encounter slow performance, high-memory usage, or long run times when you run a Delta-Normal analysis in SAS® High-Performance Risk

DetailsHotfixAboutRate It

In SAS High-Performance Risk, if you run a Delta-Normal analysis, you might encounter slow performance, high-memory usage, or long run times.

This problem occurs in Delta-Normal analysis because a block of memory that is allocated for derivatives might become very large. This memory block becomes large because of how its size is calculated:  

number of positions * number of risk factors * size of a double (8 bytes) 

However, such large amounts of memory are typically not needed.
