What does high performance computing mean?
Sorry, I am not really from a computer science background. But from the subject of it, does it mean something like multi processor programming? distributed computing? like using erlang? Sound like it, which excite me. I just had a 3 day crash course in erlang and "Cocurrency oriented programming" sounds like the edge we need today. I will be very happy to see more activity in here.

NAME
tsung - A distributed multi-protocol load testing tool.
SYNOPSIS
tsung [ -f configuration file ] [ -l log dir ] [ -m filename ] [ -r command ] [ -v ] [ -6 ] [ -h ] [ start|stop|debug|status ]
DESCRIPTION
tsung is a distributed load testing tool. It is protocol-independent and can currently be used to stress and benchmark HTTP, WebDAV, LDAP,
PostgreSQL, MySQL and Jabber/XMPP servers.
It simulates user behaviour using an XML description file, reports many measurements in real time (statistics can be customized with trans-
actions, and graphics generated using gnuplot).
For HTTP, it supports 1.0 and 1.1, has a proxy mode to record sessions, supports GET and POST methods, Cookies, and Basic WWW-authentica-
tion. It also has support for SSL.
Several config examples can be found in /usr/share/doc/tsung/examples/.
start start tsung load testing
debug start tsung with an interactive erlang shell
stop stop tsung
status print current status of a running instance of tsung (must be run on the controller host)
MANUAL
A manual should be available at /usr/share/doc/tsung/user_manual.html. It is also available online at
