Unix3 is due to be withdrawn in the near
future. A new machine unix0 / serlx27 is now available. Those authorised to have
access to unix3 also have access to unix0. A page in this format for Unix0 will
be written in the near future.

This machine is intended for use by those who need to run compute or memory intensive tasks. Use of the machine is restricted to Staff and Postgraduates. Postgraduates should get their supervisor to request access on their behalf. To get login access on this machine, you will need to contact the Computing Service Systems Group. In general, it will take overnight on any working day for access to be granted.
The specifications for this machine are:-
Compaq Alpha with 2x667MHz CPUs
1 Gigabyte RAM
100 megabit ethernet interface
Full details of what packages are available on this server can be found in the Software Catalogue.
Compaq Tru64 Unix (i.e. the same operating system as unix1 and our other older compute servers seralph1, seralph2, seralph3 and seralph4).
Compaq C/C++ compilers
Compaq Fortran F90 compiler
NAG 64bit Fortran libraries
Although the CPU speed may seem considerably less than current offerings from
Intel, the 64bit Alpha architecture typically results in much more efficient and
faster program execution speeds. Initial benchmarks indicate that this machine
is at least twice as fast as a PC with a single 600MHz CPU running a complex
fortran program (since the program was single-threaded, the second CPU was not
The machine can be used for running two types of programs
Compute intensive tasks - i.e. those (typically) requiring a long execution time.
Memory intensive tasks - i.e. those processing large data sets in-memory.
(or a combination of the above).
The machine should not be used for reading email, using the web or other network related activity. We reserve the right to remove access to those found misusing this resource in this manner.
Please note that we only allow access to this machine via SSH. Details on
obtaining and installing SSH are available at http://www2.essex.ac.uk/cs/services/ssh/ssh.htm.
