Subject: Re: [OMPI devel] About Marshalling and Umarshalling

Now I get it.

Marshalling - the process of taking a collection of data items
and assembling them into a form suitable for transmission in
a message
Unmarshalling - is the process of disassembling them on
arrival into an equivalent representation at the destination

Santhosh,

I think Ralph wants you to give your definitions for "Marshlling" and "Unmashalling".
Otherwise, it is not clear to him or others exactly what you are asking, because there are multiple possible meanings for those terms.

I wanted to know how does OpenMPI achieve marshaling and unmarshalling? If not how does it communicate with various hosts with various architectures?

Could you provide a little more definition of your terms? Just want to ensure we are talking the same language as I don't immediately see the relationship between these three questions.

Hi All,
Does OpenMPI support Marshalling/Unmarshalling? If so does it use ideal style language? If not how does it support heterogenous hosts?
