i'm running a proc nlin on a large data set, it takes forever to complete.
it runs on a big unix server with 32gb memory.
on the unix performance monitor i see that it is using full i/o and almost no memory, only 27mb.
i would expect proc nlin to be memory intensive and use a lot of it when available. is this assumption correct?
are there suggestions for performance tuning?
proc options group=memory; run;
Size parameter for sort
SUMSIZE=0 Upper limit for data-dependent memory usage during summarization
Maximum amount of memory returned when inquiring as to available space
LOADMEMSIZE=0 Suggested memory limit for loaded SAS executables
Specifies the limit on the total amount of memory to be used by the SAS System
Limit on the total amount of real memory to be used by the SAS System
