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
).

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
