Re: checkpointing architecture

[Arvind Purohit <arvind.purohit@wipro.com>]

Hi All ,

  First just give me two lines to introduce myself. I am Arvind from Bangalore,
India. I am a software engineer and very young as compared to industry standard
(just three years experience !!).

It was my willingness to be part of the forum/group/team which would decide the
future or the way futuristic machines/system would work. So I joined this group as
grid computing has enthused me right from day1 when I read about it.

But now looking at the very distinct and specialization which other people have got
on this group I am just wondering that should I be here in first place, or wait. As
looking at my current profile I can help once all things are finalized and we
intend to comeup with APIs. I would appreciate if some more documents/links can be
provided to help new members like me to learn more about check-point recovery
mechanisms in Grids.

Thanks all for your precious time,
Arvind
