| 8 | # Using the 'exit_at' feature to stop the simulation | |
| 9 | # | |
| 10 | # This explains how to enable and use the 'exit_at' feature | |

| 13 | [-] Enabling this Features: | |
| 14 | ||
| 15 | 1) Recompile legion | |
| 16 | You will need to compile legion with PERFORMANCE_CHECK=1. | |
| 17 | Edit your GNUMakefile in your legion build directory and | |
| 18 | re-compile legion. | |
| 19 | ||
| 20 | 2) Edit your config file | |
| 21 | Modify your legion config file and add the 'exit_at' value | |
| 22 | to your processor directive. | |
| 23 | ||
| 24 | Examples: | |
| 25 | processor "niagara" { | |
| 26 | clkfreq 5000000 ; | |
| 27 | cores 1; | |
| 28 | vthreads 1; | |
| 29 | nglobals 4; | |
| 30 | nwins 8; | |
| 31 | rstv 0xfff0000020; | |
| 32 | maxtl 7; | |
| 33 | exit_at 0x1234567; // stop legion when instn cnt >= 0x1234567 | |
| 34 | } | |
| 35 | ||
| 36 | [-] Output | |
| 37 | ||
| 38 | When running legion in this mode, the simulation will check for | |
| 39 | a match between instn_count and the exit_at value every 10000000 | |
| 40 | instructions. If your exit_at value is not a factor of this | |
| 41 | interval, legion will stop within 10000000 of your exit_at | |
| 42 | value. | |
| 43 | ||
| 44 | ||
| 45 | Example: | |
| 46 | ||
| 47 | fatal: Reached the value for exit_at in conf file 0x1234567, current icount=0x1312d00 | |
