Global Configuration

This page lists a number of global variables that can be used to set up the simulation engine.

They should be set before the simulation is run. Once the simulation begins they should be treated as readonly. Many of them can also be set via command line. Pass the –help argument for more information.

Setup

• g_total_lps total number of LPs
• g_num_chares total number of chares
• g_lps_per_chare number of LPs per chare (if constant)

Synchronization

• g_tw_lookahead event lookahead (conservative)
• g_tw_synchronization_protocol scheduler type
• g_tw_ts_end end time of simulation

Configuration

• g_tw_gvt_scheme GVT algorithm.
• g_tw_gvt_interval distance between GVT calls
• g_tw_gvt_trigger unit of the GVT interval (time or events)

Configuration

• g_tw_ldb_first first interval to call lb
• g_tw_ldb_iterval
• g_tw_max_ldb max number of times to call lb

Misc

• g_tw_print_interval
• g_tw_expected_events expected number of committed events
