Hi guys,
I am having some issues tuning the HPL.dat file for the Linpack benchmark test across 2 nodes. I am very new to this with minimal Linux experience, however i am trying my luck.
The specs for the two nodes are:

I read a command on every loop an execute it.
I check if the string equals the word stop to end the loop,but it say that I gave too many arguments to test.
For example echo hello.

dbd::gofer::transport::null
DBD::Gofer::Transport::null(3) User Contributed Perl Documentation DBD::Gofer::Transport::null(3)
NAME
DBD::Gofer::Transport::null - DBD::Gofer client transport for testing
SYNOPSIS
my $original_dsn = "..."
DBI->connect("dbi:Gofer:transport=null;dsn=$original_dsn",...)
or, enable by setting the DBI_AUTOPROXY environment variable:
export DBI_AUTOPROXY="dbi:Gofer:transport=null"
DESCRIPTION
Connect via DBD::Gofer but execute the requests within the same process.
This is a quick and simple way to test applications for compatibility with the (few) restrictions that DBD::Gofer imposes.
It also provides a simple, portable way for the DBI test suite to be used to test DBD::Gofer on all platforms with no setup.
Also, by measuring the difference in performance between normal connections and connections via "dbi:Gofer:transport=null" the basic cost
of using DBD::Gofer can be measured. Furthermore, the additional cost of more advanced transports can be isolated by comparing their
performance with the null transport.
The "t/85gofer.t" script in the DBI distribution includes a comparative benchmark.
