Hi guys. I am trying to test my universities cluster using the Intel Linpack Benchmarking software. Let me say from the get-go that i am a Linux novice, and only recently learnt some Linux commands to have a play around, so if you can please keep the language simple
I have run a Linpack test as can be seen from the below terminal copy and paste. However, the test that i have currently run, i believe is just testing the avg GFLOPS for the current node i am on. What if i want to test the strength of a cluster of 3 nodes all working together? Would anyone happen to know what i would need to type in the command line in order to run a test on 3 nodes that i have logged into (all clustered by the university already). The nodes are all Xeon 64's, with 4 Gigs of ram each. Would really appreciate any help.

Hi everyone,
I'm working on one HP-Unix application which we have to port completely onto Windows xp. Before that I have to compare performance of two different machines. My HP-Unix is running on HP-C8000 workstation and windows XP machine is intel Xeon. Now the problem is to evaluate the... (0 Replies)

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:

Good morning,
for the impatient: I have a new backup-server and need to monitor, what the machine can do, what's the best way of finding that out?

RNGTEST(1) General Commands Manual RNGTEST(1)NAME
rngtest - Check the randomness of data using FIPS 140-2 tests
SYNOPSIS
rngtest [-c n | --blockcount=n] [-b n | --blockstats=n] [-t n | --timedstats=n] [-p | --pipe] [-?] [--help] [-V] [--version]
DESCRIPTION
rngtest works on blocks of 20000 bits at a time, using the FIPS 140-2 (errata of 2001-10-10) tests to verify the randomness of the block of
data.
It takes input from stdin, and outputs statistics to stderr, optionally echoing blocks that passed the FIPS tests to stdout (when operating
in pipe mode). Errors are sent to stderr.
At startup, rngtest will trow away the first 32 bits of data when operating in pipe mode. It will use the next 32 bits of data to boot-
strap the FIPS tests (even when not operating in pipe mode). These bits are not tested for randomness.
Statistics are dumped to stderr when the program exits.
OPTIONS -p, --pipe
Enable pipe mode. All data blocks that pass the FIPS tests are echoed to stdout, and rngtest operates in silent mode.
-c n, --blockcount=n (default: 0)
Exit after processing n input blocks, if n is not zero.
-b n, --blockstats=n (default: 0)
Dump statistics every n blocks, if n is not zero.
-t n, --timedstats=n (default: 0)
Dump statistics every n seconds, if n is not zero.
-?, --help
Give a short summary of all program options.
-V, --version
Print program version
STATISTICS
rngtest will dump statistics to stderr when it exits, and when told to by blockstats or timedstats.
FIPS 140-2 successes and FIPS 140-2 failures counts the number of 20000-bit blocks either accepted or rejected by the FIPS 140-2 tests.
The other statistics show a breakdown of the FIPS 140-2 failures by FIPS 140-2 test. See the FIPS 140-2 document for more information
(note that these tests are defined on FIPS 140-1 and FIPS 140-2 errata of 2001-10-10. They were removed in FIPS 140-2 errata of
2002-12-03).
The speed statistics are taken for every 20000-bit block transferred or processed.
EXIT STATUS
0 if no errors happen, and no blocks fail the FIPS tests.
1 if no errors happen, but at least one block fails the FIPS tests.
10 if there are problems with the parameters.
11 if an input/output error happens.
12 if an operating system or resource starvation error happens.
