    We have here a cluster which has a mixture ia32 
and EM64T cpu's. And as we already know it is
not possible to restart a job (even a 32bit one)
that started in an 64 bit node in a 32 bit one.

However, even defining in the default script 
for the queue system a default architecture to
prevent jobs started in one to continue in other,
one user ended up restarting in the wrong architecture
producing a KERNEL PANIC !!.

So, my suggestion is, if possible, to prevent cr_restart
to proceed if it realizes that the checkpoint is from
different architecture and deliver a corresponding error
message.

We are using blcr-0.5.0_b5-1 on the 64bit nodes and
blcr-0.5.0_b1-1 on the 32bit ones. Just for your information.


Best regards,

adolfo


P.S.: again, this is just a suggestion, for a minor thing.
