We have an implementation which we run simulation from one pthread, with
lots of SC_THREADS

And control and peek simulation from another threads. We do not face any
problem.

May be you have some memory corruption issue or not locking mutual
data-structure using mutexes.

Subject: [Systemc-forum] Quickthreads problems on Linux platform using
Pthreads

 

 

Has anyone had any success in getting SystemC threads (SC_THREADS) to
work on top of a system running Pthreads on Linux?  I know from the past
few years that there was an issue with the Linux Pthread library in its
handling of certain pointers on the stack that causes errors with
malloc.  We have a validation system where the base executable is
running Pthreads and this program kicks off other tools, one of which is
a SystemC design that has test threads in it.  The test threads seg
fault with malloc due to the incompatibility described above.  Does
anyone know if it is possible to reimplement the Pthreads library or any
other workaround so these two thread systems can coexist?

Thanks, 
Patrick Carey
