It is not on your path.
Use the full path name, which should be /vti/bin/... or similar
if you did install it in /vti.

Remember, "locate" is your friend!

Are you talking about the Netlib HPL-2.0?
http://netlib.org/benchmark/hpl/

Are your computers i386 (32-bit) or x86_64/em64t (64-bit)?
"uname -a" will tell.

Anyway, read their INSTALL file for where to find
template Make.arch files!

I may have sent you the Intel MPI Benchmark link already.
Google will find it for you.

I wouldn't spend too much time benchmarking
on standard Ethernet TCP/IP.
Did you try your own programs?
