// FIXME(paddle-dev): Since the singleton of ProcessGroup in fluid is used in
|
|
// SyncBN, the fluid symbol will be dependent on external hardware access.
|
|
// Here, the part that depends on the fluid symbol is individually encapsulated
|
|
// as a temporary function to isolate external symbol dependencies.
|
|
// In the future, the dependence on the singleton in fluid in SyncBN needs
|
|
// to be removed.
|
|
// In principle, the PHI Kernel cannot use the global singleton internally,
|
|
// and the required members need to be passed in from the eucalyptus tree.
