Op che esegue un programma con aggiornamenti variabili sul posto opzionali.
Legge (facoltativamente) le variabili del dispositivo, carica ed esegue un programma TPU su un dispositivo TPU e quindi (facoltativo) aggiorna sul posto le variabili utilizzando gli output del programma, come specificato negli attributi device_var_reads_indices (indici di input del programma dalla lettura diretta delle variabili) e device_var_updates_indices (indici di output del programma utilizzati per aggiornare le variabili, -1 significa nessun aggiornamento/sola lettura). Tali output del programma vengono consumati da queste variabili e non verranno visualizzati nell'output dell'operazione. Per uso interno del compilatore TPU distribuito.
