RE: [BProc] Beoboot troubles

[Luiz O. de L. R. <ll...@st...>]

	Wilton,

	Yours aid with the PCI IDs was great and now the first and second
phase are in function.  However I am with another problem, is that boot of 1
phase does not obtain to load the archive of the one in the master, it looks
the archive in /var/beowulf/boot.img, and despite this archive being there,
it continues giving error and he does not obtain to load this image.  To
avoid this problem I am booting the slaves directly with the image of the
second phase.  

	Another one doubts is in relation to the access, in diverse
applications is used rsh to have access in the slaves, however these images
of boot does not load this service, as I must proceed then, in the case my
greater doubts is how much to the Lam-mpi, as I will make it to function
with the these in the slaves of the Beowulf.  

	The third doubts is how much the GLIBC, I compiled and installed the
Beoboot with the GLIBC without alteration, therefore I read in the
ReleaseNotes archive the following one:  

"Beoboot no longer requires a modified C library.  The dynamic linker patch
was only for demand loading of libraries which we're trying to get away
from." 

	I must really compile the original GLIBC or I can continue using
libs?  

	Thanks o lot!

	Luiz Otavio

	Wilton,

	Sua ajuda com os PCI IDs foi fundamental e agora tanto o boot da
primeira fase como o de 2 fase estao funcionado. Entretanto estou com outro
problema, e que o boot de 1 fase nao consegue carregar o arquivo do no
mestre, ele procura o arquivo em /var/beowulf/boot.img, e apesar desse
arquivo estar la, ele continua dando erro e nao consegue carregar essa
imagem. Para resolver esse problema eu estou bootando os nos escravos
diretamente com a imagem da segunda fase.

	Outra duvida e em relacao ao acesso, em diversas aplicacoes e
utilizado o rsh para acessar os nos escravos, entretanto essas imagens de
boot nao carregam esse servico, como devo proceder entao, no caso minha
maior duvida e quanto ao LAM-MPI, como farei ela funcionar com o esses nos
escravos do Beowulf.

	Uma terceira duvida e quanto a GLIBC, eu compilei e instalei o
Beoboot com a GLIBC sem alteracao, pois li no arquivo ReleaseNotes o
seguinte:

"Beoboot no longer requires a modified C library.  The dynamic linker patch
was only for demand loading of libraries which we're trying to get away
from." 

	Eu realmente tenho que recompilar a GLIBC alterdada ou poso utilizar
a original?

	Muito obrigado,

	Luiz Otavio

These id's can be extracted from a running system using the "lspci" command
as
well beoboot will list out the pci id's on the console if it fails to load a
module for the network.

Default driver information can be extracted from /usr/share/hwdata/pcitable
if 
you have the hwdata rpm installedi, be aware that the driver listed in this
file may not always be the best driver to use on you particular version of
hardware, for example there are two different drivers one can use for a
sym53c8xx scsi card, the default "sym53c8xx.o" hasn't worked very well for
us
causeing all sorts of problems with DMA, but if we use the "sym53c8xx_2.o" 
driver everything works flawlessly.

Also a current list of pci ids can be obtained from: 
http://pciids.sourceforge.net/
