HANDLE-SIGNALS

Syntax
HANDLE-SIGNALS <triplets of signal numbers>
Variable
VT_HANDLE_SIGNALS
Default
none in
libVTcs
, all in other fail-safe libs
Description
This option controls whether the Intel Trace Collector replaces a signal handler previously set by the application or runtime system with its own handler.
libVTcs
by default does not override handlers, while the fail-safe MPI tracing libraries do: otherwise they would not be able to log the reason for an abort by MPI.
Using the standard triplet notation, you can both list individual signals (Example:
3
) as well as a whole range of signals (
3,10:100
).
