Question about BProc process migration/ Scyld.

[Todd Chapman]

Hi,

I have worked with Beowulf systems and MPI in the past, but am considering
diving into Scyld's tools to help build a cluster for a large company.

I'm a systems administrator, not a C programmer. After reading the BProc
documentation I am a bit confused. It mentions that the process migration
process is not transparent. Questions I have are:

1. Dou you need access the the program's source code to make modifications
for process migration?

2. Or, can a wrapper be written that is migrated and spawns the real
application?

If there is any documentation that explains this more plainly than the
Scyld documentation I would really be interested.

Thanks.
