ScaLAPACK functions in the MKL and Ethernet network

Hello.
In our class there are 20 computers, Intel Core 2 Duo in each. They are interconnected by simple 100Mbit Ethernet network using one Ethernet switch and twisted-pair.
The question is: is it reasonable to use ScaLAPACK functions (e.g. pdgetrf) at this network and 20 computers? Or I have to use just LAPACK functions (e.g. dgetrf) at single computer?
Thanks!

Hello,
depends the task size. if the task size match with RAM available on single computer then please use Lapack version of dgetrf if not then -ScaLapack.

Thanks for your answer!
Yes, the taks's data can be stored in one RAM on single computer.

Another question - is there any solution (may be not Intel :)) that will yield some performance in such Ethernet network?
