Our lab has recently acquired a 48-node IBM SP configuration based on
4-way "Winterhawk-II" Power3-2 wide nodes with 8 GB memory. I see on the
Linuxppc site (boxes) that Linux is known to work on 9076-SP nodes
(ours). How difficult is the port? IBM does not support Linux on the
9076 but does on the newer Power4 pSeries units.

I've recompiled & run both 2.4-marcelo, 2.4-redhat, 2.4-suse (which are all very different) and 2.6-torvalds kernels on a 2-way power3 box and 'it just works'. I can't imagine why it wouldn't 'just work' on an SP. I'm guessing that the hard part for you will be to get the interconnect between the machines running. I assume this will need some funny device driver for whatever the interconnect technology is (which you didn't mention). --linas ** Sent via the linuxppc-dev mail list.

Getting the os on there may require some creativity, since sp nodes don't come with a removable media, so you'll have to net-boot&install, but iirc, these boxes basically do tftp, but I guess you still need a working control-workstation to be able to set the netboot. (I have never had the oppertunity to play with an sp-node at this level) as long as you don't need the sp switch (if you have one) all hardware is supported, ge, fe and even the scsi are quite common hardware, just with an IBM sticker&price-tag ;-) (I wish I had a few spare wh-II's to play with :) > Bill Noffsinger > bnoffsi@ufl.edu > > > > -- Met vriendelijke groeten, Remco Post SARA - Reken- en Netwerkdiensten http://www.sara.nl High Performance Computing Tel. +31 20 592 8008 Fax. +31 20 668 3167 "I really didn't foresee the Internet.

We've booted linux on winterhawks in the past, there was one weird problem where we allocated memory for RTAS too high but that should be fixed. As pointed out we have no support for the switch unfortunately. One of our build machines here is a nighthawk (16 way 9076) and it works nicely in case anyone has a cluster of these lying around :) Anton ** Sent via the linuxppc-dev mail list.

* how to read/write registers of CPU or Device from user space 2004-01-10 13:02 ` Remco Post @ 2004-01-12 2:20 ` John Zhou 0 siblings, 0 replies; 6+ messages in thread From: John Zhou @ 2004-01-12 2:20 UTC (permalink / raw) To: linuxppc-dev Hi, all, when debugging kernel or driver, we need to read/write registers of CPU and devices. I wanna use /dev/mem to do, is it possible? if need to do others things? is it better to write a driver for read/write CPU/device's registers by myself? Do you have any good advice? Thanks in advance! John ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/ ^ permalink raw reply [flat|nested] 6+ messages in thread
