Description:
Multithreaded tracing library
FxT is a library and associated tools that can be used to analyze the performance of multithreaded programs which can potentially use a hybrid thread scheduler (i.e. a user-level scheduler on top of a kernel-level one). The Marcel thread library can take full profit from this library. . FxT is based on the offline analysis of traces (sequence of events recorded at run time). . This package contains static libraries and development headers.
