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:

eurephia_init(7)eurephia_init(7)NAME
eurephia_init - Initialisation utility for the eurephia OpenVPN plug-in.
SYNOPSIS
eurephia_init [-V|--version] [-h|--help] [-l|--log <filename>] [-L|--log-level <log level>] [-N|--hash-threshold-min <ms>]
[-M|--hash-threshold-max <ms>] [-D|--database-driver <path>] [-d|--database-args <args>]
DESCRIPTION
This utility is only supposed to be used when installing eurephia. The purpose is to initialise the database eurephia will use, by setting
up some standard configuration values and create an administrator account
OPTIONS
Arguments used by eurephia_init:
-V | --version
Show version information
-h | --help
This help screen
-l | --log <filename>
Log file for debugging
-L | --log-level <log level>
Sets the log level
-N | --hash-threshold-min <ms> : Benchmarking parameter, see below. Default 95ms
-M | --hash-threshold-max <ms> : Benchmarking parameter, see below. Default 200ms
-D | --database-driver <full path>
Full path to the database driver (Required)
-d | --database-args <arguments>
Required database arguments for the driver (Required)
BENCHMARKING
During the initialisation this utility will benchmark the CPU power by doing multiple SHA512 hash calculations. This is to determinate the
optimal rounds the password hashes should use on the current computer. To make it more difficult to brute force passwords, eurephia imple-
ments dynamic password hash rounds, based on a random number within in a given range. This benchmark will suggest an optimal range. To do
this, two limits are defined, the shortest time and the longest time to be used for calculating a hash. The default values are 95ms and
200ms.
If you want to modify those thresholds, you can do so with the --hash-threshold-min and --hash-threshold-max options. By increasing these
numbers, you will allow the number of rounds to be increased.
