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).
