Charm++ offers a variety of parallel debugging options,
from the extremely basic to the extremely sophisticated.
The traditional debugging methods, such as logging (via
the CkPrintf routine) and interactive debugging (via the
"++debug" command line option) are supported under Charm++.
In addition, Charm++ offers several additional features
designed to simplify application development. Linking
with "-memory paranoid" checks all dynamic heap allocation
calls for common errors, such as double-delete, random-delete,
read-after-delete, buffer over- and under-write errors.
Charm++, when compiled without "-DCMK_OPTIMIZE", contains
hundreds of assertations to catch invalid parameters and
unintialized data passed to API routines.
We are working on a sophisticated parallel debugger, with
the ability to set breakpoints, examine variables, objects,
and messages across the entire machine. The design of this
debugger is described in the paper below.
