@YUUU23 YUUU23 commented Jun 16, 2024

To introduce the --assert_all_regions_parallelizable flag (should exit with error when both UnparallelizableError and general exception are caught) and changing the original --assert_compiler_success flag to exiting with error only when general exceptions are caught (does not exit with error when UnparallelizableError are caught), the following were added:

  • compiler/orchestrator_runtime/pash_init_setup.sh, compiler/cli.py : set-up and add information regarding --assert_all_regions_parallelizable flag for pash to recognize

  • compiler/custom_error.py: introduce NotAllRegionParallelizableError to be raised when UnparallelizableError are caught in the compile.ir function in pash/compiler/pash_compiler.py ;

    • the NotAllRegionParallelizableError will be caught in compiler/pash_compilation_server.py when the compile.ir function is called; if this error is caught, the new variable all_region_parallelizable in compiler/pash_compilation_server.py will be marked false
    • to differentiate all regions not parallelizable from general error, a error_response with a different error message is saved in the compiler server
    • don't increase the running procs if assert_compiler_success flag is on and compile_success is false but all_region_parallelizable is true (some general exceptions caught) ; or assert_all_regions_parallelizable flag on and compile_success is false because of both general exceptions or unparallelizable region
  • compiler/orchestrator_runtime/pash_prepare_call_compiler.sh: marks variable pash_all_region_parallelizable if error_response contains message regarding regions not being parallelizable. We should exit on error when,

    • assert_all_regions_parallelizable flag on and runtime_return_code != 0 : general exception
    • assert_all_regions_parallelizable flag on and pash_all_region_parallelizable != 0 : some region is not parallelizable
    • assert_compiler_success_flag flag on and runtime_return_code != 0 and pash_all_region_parallelizable == 0 : general exception (and not error because some regions were not parallelizable)
  • evaluation/tests/test_evaluation_scripts.sh : when executing tests, change --assert_compiler_success to --assert_all_regions_parallelizable, since what assert_compiler_success originally does is now carried out by --assert_all_regions_parallelizable

Tested the above for expected behavior by running some intro scripts in the directory, and it does seem like we are exiting with error for --assert_compiler_success only when general exceptions are caught and not the unparallelizable ones. We are also exiting on error for both reasons when --assert_all_regions_parallelizable flag is on. When both flags are used at the same time, we follow the behavior of --assert_all_regions_parallelizable. PaSh testing scripts locally also seems to pass all tests.

Looks great, if you can do the small changes that I suggest we can merge :)

Maybe we can add a comment that this is strictly stricter than --assert_compiler_success

if compile_success:
response = server_util.success_response(
f"{process_id} {compiled_script_file} {var_file} {input_ir_file}"
)
elif not all_region_parallelizable:
# send specified message to say not all regions are parallelizable instead of general exception caught
response = server_util.error_response(f"{process_id} not all regions are parallelizable; failed to compile")

The response can be more specific, and slightly reworded. At this point we know precisely which region is not parallelizable, and we can respond with that (instead of a more generic "not all regions"). Also, the all_region_parallelizable flag could be renamed to current_region_parallelizable or parallelizability_success since it refers to a specific region and not all regions.

would it be okay to response with "current region" along with the process_id? I'm not entirely sure how to refer to a region
Thank you for the reviews!

…tion as old assert_compiler_success flag; new assert_compiler_success flag now will not exit with error when regions are unparallelizable and exit with error when general exceptions are caught
