The goal of this page is to bring together links and documents on research projects as well as commercial products involving the use of Linux in these environments. Linux is a free POSIX-compatible UNIX clone which runs on 386/486/Pentium and Alpha-based systems. Because all of the source (including the kernel) is copylefted, it's an attractive operating system for people involved in operating systems and clustered-computing research. The complete operating system and thousands of applications are free, and it runs on inexpensive commidity PC hardware. I'd like to expose and promote Linux as an O/S alternative for research and teaching in high-performance systems. The Linux-HPC page is http://www.cs.cornell.edu/home/mdw/hpc/hpc.html If you're involved in parallel/networking systems work related to Linux, please feel free to contribute to these pages my sending e-mail to mdw@cs.cornell.edu.

I had really bad timing with the Linux mailing list creation ... Anyway, since you're so busy and quiet and since the PowerPC Linux page (http://speedy.redhat.com/ppc/) just had some really good news (Linux on PPC is now real) I thought about maintaining the one email/week traffic. In the latest reorg memo, TJ wrote (quote): "We will increase competitive pressure on other suppliers such as Sun and HP and Wintel based PC products by directly attacking their low-end workstation offerings with superior technology and better price-performance." This is revolutionary thinking at SGI. Moreover, it is a clear green light from up above to change the way we think. Free-software should be a part of that strategy. So, please take some time, and read the following: http://info.engr.sgi.com/~ariel/linux/free-software.html (the first one was written for those who are not familiar with free software, for you it may be obvious) And then, read some specifics in: http://info.engr.sgi.com/~ariel/linux/ Send me your comments.

Reply-to: Andrew.Tridgell@anu.edu.au David, I've managed to get Linux on our AP1000+ booting up to the stage where it detects a Viking MMU and dies. The main problem was that the machine has no prom at all, so all the calls to the prom routines needed amputation to get it to work. Instead of a prom the hardware has a mechanism for loading a image from the front end at 0xF0000000 and launching it. I wrote a small boot loader that runs at this address then pulls a vmlinux from the front end then jumps to it. I finally got this working today. I've also written an ap_printk() routine that uses lda/sta to write to the front end, and wired both prom_printf() and printk() to that. I'll let you know as I make more progress, meanwhile here are the first signs of life from Linux/AP+: @load aout vmlinux 488k load finished @jumping to 0xf0004000 @Hello from Linux! @got to line 0198 @got to line 0206 @ARCH: @SUN4M @Uh oh, IDPROM had bogus id_machtype value <0> @Ethernet address: 0:0:0:0:0:0 @Loading srmmu MMU routines @Viking MMU detected. The '@' symbols and from my monitor program - they helped debugging the protocol. Cheers, Andrew PS: In case you can't remember a AP1000+ is a SuperSparc based distributed memory multicomputer made by Fujitsu. Ours has 16 cpus each with 16MB of ram. We will soon be upgrading it to 32 cpus with 64MB of ram in each and 128GB of disk. ------- End of forwarded message ------- From owner-linux@cthulhu.engr.sgi.com Thu Mar 14 02:23:50 1996 Received: from cthulhu.engr.sgi.com by neteng.engr.sgi.com via ESMTP (950413.SGI.8.6.12/940406.SGI.AUTO) id CAA18142; Thu, 14 Mar 1996 02:23:49 -0800 Return-Path: Received: by cthulhu.engr.sgi.com (950511.SGI.8.6.12.PATCH526/911001.SGI) for linux-list id CAA16030; Thu, 14 Mar 1996 02:23:45 -0800 Received: from neteng.engr.sgi.com by cthulhu.engr.sgi.com via ESMTP (950511.SGI.8.6.12.PATCH526/911001.SGI) for id CAA16025; Thu, 14 Mar 1996 02:23:43 -0800 Received: from cthulhu.engr.sgi.com by neteng.engr.sgi.com via ESMTP (950413.SGI.8.6.12/940406.SGI.AUTO) for id CAA18137; Thu, 14 Mar 1996 02:23:43 -0800 Received: from sgi.sgi.com by cthulhu.engr.sgi.com via ESMTP (950511.SGI.8.6.12.PATCH526/911001.SGI) for id CAA16020; Thu, 14 Mar 1996 02:23:42 -0800 Received: from caipfs.rutgers.edu by sgi.sgi.com via ESMTP (950405.SGI.8.6.12/910110.SGI) for id CAA03175; Thu, 14 Mar 1996 02:23:41 -0800 Received: from huahaga.rutgers.edu (huahaga.rutgers.edu [128.6.155.53]) by caipfs.rutgers.edu (8.6.9+bestmx+oldruq+newsunq+grosshack/8.6.9) with ESMTP id FAA11619; Thu, 14 Mar 1996 05:21:17 -0500 Received: (davem@localhost) by huahaga.rutgers.edu (8.6.9+bestmx+oldruq+newsunq+grosshack/8.6.9) id FAA08455; Thu, 14 Mar 1996 05:21:16 -0500 Date: Thu, 14 Mar 1996 05:21:16 -0500 Message-Id: <199603141021.FAA08455@huahaga.rutgers.edu> From: "David S.
