Hello all,
I have 4 questions regarding the Chapel domain map framework and I tried
to put them in correct terms, If you find any mistakes feel free to ask me
to change.
1.) By the term "Every domain should have the associated domain map" the
domains which are not explicitly given the name of domain map. Like
const probelmspace = {1..6, 1..10} what domain map will the domain value
probelmspace has ?
2.) I find that " distributions are written by using layouts "
For example
block domain map has constructor parameters
* boundingbox which is a non-distributed
domain which in the sense it is a domain which follows layout
* target dom which in turn is a domain
following layout.
* On each global descriptor - this got used
like ( example in block dist global descriptor) each locale has local
descriptor which has a locdom which
is a
layout domain.
In global domain descriptor has the
non-distributed array of locdom.which is used by global array descriptor to
create a non-distributed array over
the locdom. By analyzing this the original
block array is stored has the collection of individual array mapped via
layout.\
3) I know we can dynamically extent / contract the domains. By doing so
whether the array declared over that domains get invalidated if their
elements (indexes) are destroyed ?
4.) this is more abstract : How the layouts defines the storage of
domains/arrays ?
Thanks
Pree
