HydraVM: Low-Cost, Transparent High Availability for Virtual Machines - Hou, Kai-Yuan; Uysal, Mustafa; Merchant, Arif; Shin, Kang G.; Singhal, Sharad
Keyword(s): Virtualization, High Availability, VM Checkpointing, VM Restore, Shared Storage
Abstract: Existing approaches to providing high availability (HA) for virtualized environments require a backup VM for every primary running VM. These approaches are expensive in memory because the backup VM requires the same amount of memory as the primary, even though it is normally passive. In this paper, ...

addbddnode
ADDBDDNODE(3) BDD FUNCTIONS ADDBDDNODE(3)
NAME
addbddnode - adds a new bdd node in the bdd system.
ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
Paris, France.
Web : http://asim.lip6.fr/recherche/alliance/
E-mail : alliance-users@asim.lip6.fr
SYNOPSYS
#include "bdd101.h"
bddnode *addbddnode( BddSystem, Index, High, Low )
bddsystem *BddSystem;
bddindex Index;
bddnode *High;
bddnode *Low;
PARAMETERS
BddSystem The bdd system.
Index The bdd index.
High The bdd high pointer.
Low The bdd low pointer.
DESCRIPTION
addbddnode adds a new node with the index Index, High as HIGH pointer, and Low as LOW pointer in the bdd system BddSystem. If the bdd node
exist already addbddnode return its pointer. If a null pointer is given, the default bdd system is used.
RETURN VALUE
addbddnode returns a pointer to the resulting bdd node with its number of external reference incremented.
ERRORS
"index xxx out of range"
The Index parameter must be a valid index.
EXAMPLE
#include "bdd101.h"
bddsystem *BddSystem;
bddcircuit *BddCircuit;
bddnode *BddNode;
chain_list *Expr;
BddSystem = createbddsystem( 100, 1000, 100, 50000 );
BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
BddNode = addbddcircuitin( (bddcircuit *)0, "i0", 0, BDD_IN_MODE_FIRST );
BddNode = addbddnode( (bddsystem *)0, BddNode->INDEX, BddNode->LOW, BddNode->HIGH );
Expr = convertbddcircuitabl( (bddcircuit *)0, BddNode );
/* displays (not i0) */
viewablexpr( Expr, ABL_VIEW_VHDL );
freeablexpr( Expr );
destroybddsystem( (bddsystem *)0 );
destroybddcircuit( (bddcircuit *)0 );
