Comments: To: Ya Huang <ya.huang@AMYLIN.COM>

a difference I observed, but not documented is that some procedures that are
not multi-threaded in PC SAS actually can leverage multi cores in a server
version.

I tried PROC PRINCOMP to conduct a PCA on a moderate size, 1000-by-1000,
real matrix. When the commands were executed on our server, the CPU time is
larger than real time, which means mutli-threading or multiple cores are
involved in the analysis; but on our workstation which has PC SAS, the real
time is larger than the CPU time, which definitly is single threaded.

SAS Doc didn't mention PRINCOMP in their list of procedures that can use
multi-threading or multi-cores, however. I guess PROC FACTOR may also be
improved.

Overall, I am so far satisfied with the server environment for analysis,
comparing to the PC enviornment in my previous company
