I was able to succesfully run xhpl using your HPL.dat file on 6 processors across 2 nodes.
The command used was:
(Note the "-mca btl tcp,self" is to avoid warnings and errors w.r.t. Infiniband, which we don't have here. If this is your problem, it's still your admin's fault!)
The machines file was as follows:
The HPL.dat file was identical to the one you posted here, with the exception of Q = 3 (since I have one 4-cpu host and one 2-cpu host). Also HPL.out was changed to 340 for speed reasons, but prior tests indicated it worked well to at least 2500 on my hosts. Large values of N may cause the system to run out of memory, but this would be a different error.
To compile the HPL program, I used the command "make arch=TIS" (my firm is called Tiscover) and the following Makefile (Make.TIS). For your admin's sake, I have hilighted some important changes:

whereis
whereis(1B) SunOS/BSD Compatibility Package Commands whereis(1B)NAME
whereis - locate the binary, source, and manual page files for a command
SYNOPSIS
/usr/ucb/whereis [-bmsu] [ -BMS directory... -f] filename...
DESCRIPTION
The whereis utility locates source/binary and manuals sections for specified files. The supplied names are first stripped of leading path-
name components and any (single) trailing extension of the form .ext, for example, .c. Prefixes of s. resulting from use of source code
control are also dealt with. whereis then attempts to locate the desired program in a list of standard places:
etc
/sbin
/usr/bin
/usr/ccs/bin
/usr/ccs/lib
/usr/lang
/usr/lbin
/usr/lib
/usr/sbin
/usr/ucb
/usr/ucblib
/usr/ucbinclude
/usr/games
/usr/local
/usr/local/bin
/usr/new
/usr/old
/usr/hosts
/usr/include
/usr/etc
OPTIONS
The following options are supported:
-b Searches only for binaries.
-B Changes or otherwise limits the places where whereis searches for binaries.
-f Terminates the last directory list and signals the start of file names, and must be used when any of the -B, -M, or -S options are
used.
-m Searches only for manual sections.
-M Changes or otherwise limits the places where whereis searches for manual sections.
-s Searches only for sources.
-S Changes or otherwise limit the places where whereis searches for sources.
-u Searches for unusual entries. A file is said to be unusual if it does not have one entry of each requested type. Thus
`whereis -m-u *' asks for those files in the current directory which have no documentation.
EXAMPLES
Example 1: Finding files
Find all files in /usr/bin which are not documented in /usr/share/man/man1 with source in /usr/src/cmd:
example% cd /usr/ucb
example% whereis -u -M /usr/share/man/man1 -S /usr/src/cmd -f *
FILES
/usr/src/*
/usr/{doc,man}/*
/etc, /usr/{lib,bin,ucb,old,new,local}
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWscpu |
+-----------------------------+-----------------------------+
SEE ALSO chdir(2), attributes(5)BUGS
Since whereis uses chdir(2) to run faster, pathnames given with the -M, -S, or -B must be full; that is, they must begin with a `/'.
