RE: [BProc] Newbie questions

[YhLu <Yh...@ty...>]

Bproc doesnt need LinuxBIOS.  Beoboot will produce kernel and initrd.  You
can use that for PXE. 
 
As for LinuxBIOS you may use Etherboot in your rom.  Then you need
mkelfimage
 
At the same time you still can use Etherboot to produce .zpxe as your PXE
load so
 
Normal BIOS + PXE + tg3.pxe (Etherboot)+ elf ( from mkelfimage kernel +
initrd) = LinuxBIOS ( tg3.zelf = Etherboot in ROM) + elf ( Kernel + initrd).

Subject: [BProc] Newbie questions
 
Hi folks, 
I am trying to build a small 5-node cluster using RedHat 9.x base
installation, and the bproc and beoboot available at sourceforge. I was able
to successfully build and run the bproc-patched kernel and bproc (bpmaster,
bpstat, etc. However, I have problems building the beoboot. I have included
what I have done below (section E); and included the steps (step 28, steps
22, 27) I am having trouble with. Can any of you please help either by
telling me where I am screwing up or pointing out a good doc (I have already
looked at the doc at bproc home page; and a Bproc reference manual by Eric)?
Any help will be appreciated.
Thanks. 
Another option I am considering is using ClusterMatic 4.0, but it seems to
require LinuxBIOS to boot. Is LinuxBIOS REQUIRED on all (compute) nodes for
Clustermatic to work? Can I still use PXE/beoboot (with beoboot -1 image on
floppy on slave nodes)?
Thanks.

DETAILED ACTIONS TAKEN TO BUILD BPROC UTILITIES FROM SOURCEFORGE: 
A. DOWNLOAD KERNEL AND BPROC PATCH AND BPROC SOURCES. 
1. download linux-2.4.21.tar.gz from  <file:///\\www.kernel.org>
www.kernel.org to /home/vdeokar/kernel_sources 2. download
bproc-3.2.6.tar.gz from sourceforge.net to /home/vdeokar/kernel_sources
(BPROC sources and patch to kernel
 
B. PATCH, CONFIGURE & BUILD KERNEL 
3. Apply bproc patch to kernel sources unzipped at
/home/vdeokar/kernel_sources/linux-2.4.21 (gzip -dc ../bproc-3.2.6.tar.gz |
patch -p1)
        Failed in the end with following msg, but thats the last line of the
patch file, and really seems to have succeeded.
        "patching file arch/ppc/kernel/misc.S 
        patch unexpectedly ends in middle of line" 
4. Copy /boot/config-2.4.20-31.9 (exisiting kernel config file) to .config
in linux-2.4.21 5. make oldconfig (set CONFIG_BPROC=y) 6. Build kernel (make
dep; make bzImage) 7. SKIP - Build Bproc (as in BProc manual with
LINUX=/home/vdeokar/kernel_sources/linux-2.4.21)
8. make modules 
9. Become root 
10. make modules_install 
11. cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.21-bproc3.2.6 and System.map
and config file. 
12. mkinitrd /boot/initrd-2.4.21.bproc326.img 2.4.21 13. Edit GRUB file. 
14. Reboot with new kernel and login as root 
 
C. BUILD AND INSTALL BPROC 
15. Do step 7 (build bproc here). make
LINUX=/home/vdeokar/kernel_sources/linux-2.4.21 
16. Install (per PDF doc by Eric) from bproc dir. make
LINUX=/home/vdeokar/kernel_sources/linux-2.4.21 install. 
17. Reboot and login as root 
18. modprobe bproc (Install BProc) 
19. Run bpmaster (check /etc/beowulf/config). Ready for global process
sharing. 
20. Before bpstat I needed to create symlink (ln -s libbproc.so.2.5.0
libbproc.so.2) in /usr/lib 
 
D. DOWNLOAD, BUILD, INSTALL CMTOOLS 
21. Download cmtools1.2 from sourceforge bproc. 
???  22. Should I patch kernel? I did not since I do not have package mpi or
mpich installed....looked like all MPI library patches; and patch --dry-run
failed many HUNKS.
23. Build cmtools; had to introduce $CC environment variable to gcc. make
LINUX=/home/vdeokar/kernel_sources/linux-2.4.21
24. (Install cmtools) make LINUX=/home/vdeokar/kernel_sources/linux-2.4.21
install 25. Run ldconfig 
 
E. DOWNLOAD, BUILD, INSTALL BEOBOOT 
26. Download beoboot-cm1.5 from dourceforge bproc. 
??? 27. Did not patch as most seemed to be for 2.4.17 kernels. 
??? 28. Tried to build but needs libmodutils.a, libmodutilobj.a,
libmodutilutil.a, libz.a which is not on this machine. DO I need to get a
patch from somewhere else? 
28a. Modutils-2.4.28 rpm already exists (installed) on the systems. (No need
to download, make and make install modutils from  <file:///\\www.kernel.org>
www.kernel.org )
STUCK HERE 
TRIED FOLLOWING... 
28b. Need to do this before 28c - a force install of modutils: Download from
<file:///\\ftp.gnu.org> ftp.gnu.org bison, flex. configure, make and make
install.
28c. Download modutils-2.4.21.tar.gz. 
28d. If I change the Makefiles and proceed to force-build and install
beoboot, beoboot fails later when I am trying to create -1 and/or -2 images
with undefined references to insmod_main, rmmod_main, etc.:
I modified the 2 Makefiles to make it build to remove linkage from these
modutil* libraries. (make LINUX=/home/vdeokar/kernel_sources/linux-2.4.21 )
29. Install (make LINUX=/home/vdeokar/kernel_sources/linux-2.4.21 install
2>&1 | tee makebeobootinstall.log) 
F.Start using 
30. Reboot and login as root. 
31. Run "service beowulf start"
