Hi, Nathan: Thank you for your response. I think that I have no ability to implement the system calls. Therefore, I should try another alternative. I have also tried to run M5 in full system mode. However, when I put the executable binaries in the image and mount it in the simulated system, the programs always suffer "Killed" or "Segmentation fault". Not only the threaded executables encounters the problem, but also non-threaded version. In fact, I can not execute any benchmark in the SpecOMP in ALPHA full system simulation environment.
My steps are 1) compile the benchmarks of SpecOMP by the pre-compiled cross-compiler for ALPHA obtained from M5 website. 2) create a disk image and put the compiled binaries in the image. 3) run a full system simulation by ALPHA_FS/m5.fast with the disk image obtained from M5 website. 4) mount the benchmark image in the simulated system. 5) run the binaries in the simulated system. There is no error message in both the simulated system and M5 except "Killed" and "Segmentation fault". Does it mean that M5 full system simulation can not support OMP threaded applications? Or I do something by mistake. How can I obtain some additional error message besides "Killed" or "Segmentation fault" to know what is wrong in the simulated system?
