VNC on XWindows platforms creates a local virtual XWindow desktop that supports your choice of window managers, has low latency and can be viewed by a phelora of platform supporting viewers off your client machine of choice. I am using a JAVA viewer, as I lack local admin. The X tcp or unix sockets run inside the host for min laatency (unless you point off-host X clients to it), and a VNC socket connects the viewer. You can run the VNC tcp though an ssh tunnel for security.
Heterogenous clustering requires smarter load balancing and code compatability or porting. Java is portable, compared to C++/g++, which produces code specific to the CPU and O/S, but still is very widely available to compile locally compatible code.
VM makes sense. In practice, very few modern systems page much, and it makes the environment that much more robust. It can support huge sparse matrixes in an mmap()'d space, key to many problems.
Going highly parallel on cpu and ram suggest that net and file access will become bottlenecks, so yes, you need to put lots of work into making them as parallel as possible, too. Network fabric needs to be many path switches and high bandwidth. If you go fiber with either, remember that with its higher speeds comes higher latency, so problems may need to be structured to avoid that. Net and file have been becoming the same problem, as more and more file is remote from the host.

Hi Guys,
I'm busy building a LVS-NAT cluster on Red-Hat server 5.1 and I need a kernel that has LVS capabilities for a red-hat server 5.1. Is the anyone who can advise me where I can get this kernel. I have already visited the following site Ultra Monkey: and this has old kernels e.g. 2.4.20... (2 Replies)

NAME
bssh/bvnc/bshell - Browse for SSH/VNC servers on the local network
SYNOPSIS
bssh
bvnc
bshell
DESCRIPTION
bssh/bvnc/bshell browses for SSH/VNC servers on the local network, shows them in a GUI for the user to select one and finally calls
ssh/vncviewer after a selection was made.
If the binary is called as bssh only ssh servers will be shown. If the binary is called as bvnc only VNC servers will be shown. If the
binary is called as bshell both VNC and SSH servers are shown.
OPTIONS
-s | --ssh
Browse for SSH servers (and only SSH servers) regardless under which name the binary is called.
-v | --vnc
Browse for VNC servers (and only VNC servers) regardless under which name the binary is called.
-S | --shell
Browse for both VNC and SSH servers regardless under which name the binary is called.
-d | --domain= DOMAIN
Browse in the specified domain. If omitted bssh/bvnc/bshell will browse in the default browsing domain (usually .local)
-h | --help
Show help.
