hpl benchmark result of Sun V210 cluster solaris9

Hi,

I run hpl benchmark program on Sun V210 cluster ;48 computation node , O.S
solaris 9.0. performance result is very bad approximately 10 percent of
peak performance. I couldn't define the reason of this situation .is it
possible to improve it?

optimization of blas library effects the HPL results very high. I use
-xlic_lib=sunperf for linking blas lib.are there any options for more
optimized blas lib for sun solaris 9.0. Also I use -fast -xO5 -xarch=v9b
-xchip=ultra3 optimization flags.


Any idea to help,please?
thanks
