Hello,
I've noticed that with SystemC 2.3.3, when I spawn a dynamic process, there is a huge memory consumption.
Here' s the code generating the problem
#include "test_module.h"
void test_module::my_process(int temp) {
printf("thread spwned @ %.1f\n",sc_simulation_time());
wait(1000,SC_NS);
}
void test_module::test_thread(void) {
int temp=0;
while(true) {
printf("current time is %.1f\n",sc_simulation_time());
if (sc_simulation_time()>=100000000) {
printf("stop here\n");
wait();
sc_stop();
}
else {
sc_spawn_options my_thread;
sc_process_handle test_proc;
my_thread.set_sensitivity(&clock.pos());
test_proc = sc_spawn(sc_bind(&test_module::my_process,this,temp),NULL,&my_thread);
wait(10,SC_NS);
}
}
}
Basically, when I run the program I see the memory associated to the process steadily growing up second after second.
SystemC has been configured with the following switches:
--enable-shared=no
--disable-async-updates
and compiled as static library.
The host OS is ubuntu 16.04 and G++ version is 5.4.0 20160609
The same code compiled on an ubuntu 10.04 with SystemC 2.2.0 does not show any memory problem.
Any idea on why this happens?
Thanks
