From December 9th, the family of public computing clusters in the computer centre will be expanded to include Linux services. There will be a new interactive cluster, LXPLUS, and also a new public batch cluster running Linux, LXBATCH. From December 9th, therefore, the following public services will be available.
|LXPLUS||15 dual CPU PCs (with 550MHz Intel PIII processors)|
|RSPLUS||15 dual CPU IBM 43P-240 workstations|
|HPPLUS||5 dual CPU HP J2240 workstations|
|DXPLUS||5 dual CPU DEC PWS500 workstations|
|LXBATCH||20 dual CPU PCs (with 550MHz Intel PIII processors)||5000 CERN Units|
|RSBATCH||15 IBM 43P-140 workstations (with one 332MHz PowerPC
18 IBM 43P-850 workstations (with one 166MHz PowerPC processors)
|2040 CERN Units|
The table shows clearly that these new services are a major addition to the public service family. The relatively low price of PCs has allowed us to significantly increase the available batch capacity and COCOTIME has agreed to increase the Linux based batch capacity to at least 10,000 CERN Units next year if there is a demand for this service. So, it may take a bit of effort to convert your programs to Linux but the rewards in terms of improved turnround and capacity should make the effort worthwhile!
The AIX based public interactive and batch services will be in the last year of their normal lifetime during 2000. The maturity of PC and Linux systems is such that we expect LXPLUS and LXBATCH to take over. But remember they are PCs, so please use your "Desktop PC" (in local mode) for Netscape, mail and other interactive applications.
Linux is a freely distributed multi-tasking multi-user Operating System that behaves like the UNIX operating system in terms of kernel behaviour and peripheral support. Linux has all the features of UNIX, plus several recent extensions that add new versatility to Linux. All source code for Linux and its utilities is freely distributed. Linux was designed specifically for the PC (Intel CPU) platform and takes advantage of its architecture to give you performance similar to high-end UNIX workstations. A number of ports of Linux to other hardware platform have also appeared, and they work much like the PC version. It has all the features you would expect in a modern fully-fledged UNIX, including:
Here, at CERN, Linux is now well supported and all the major
software including CERNLIB, AFS, LSF, GNU and the public domain
software from ASIS is available. In the past access to Linux was
restricted to experiments with dedicated servers. With the
introduction of the LXPLUS and LXBATCH services, all users have
access to a Linux platform. In particular, we hope that the
significant batch capacity will make these services attractive for
physics applications. The new services will be available from
December 9th; until then users who are willing to test the new
services can login into LXTEST.
