! Subroutine: psb_icdasb
|
|
! Assemble the psblas communications descriptor: inner part.

|
|
! Arguments:
|
|
! desc - type(psb_desc_type). The communication descriptor.
|
|
! info - integer. return code.
|
|
! ext_hv - logical Essentially this distinguishes a call
|
|
! coming from the build of an extended
|
|
! halo descriptor with respect to a normal call.
