Hello to all, We are trying to generate checkpoints from already created SimPoints, taken from SPEC CPU2006. Although we have followed the instructions shown in the MARSSx86 wiki page, it does not seem to work properly. The image is downloaded from the wiki (ubuntu-natty.qcow2) and the benchmarks are built in the same image. As a result, a couple of checkpoints are created and then the image freezes unexpectedly. Sometimes, it generates all the checkpoints, but unfortunately they are wrong, that is, they were taken in almost the same instructions. Below is the procedure that we followed: 1. Booting MARSSx86, using default configurations: qemu/qemu-system-x86_64 -vnc :10 -m 4096 -hda /opt/images/ubuntu-natty.qcow2 2. By using of "create_checkpoint" binary (provided by ubuntu-natty.qcow2), we created the initial checkpoint at the beginning of the benchmark: e.g.: ~/create_checkpoint bzip2; ./bzip2_base.gcc43-64bit chicken.jpg 30 > /dev/null; ~/stop_sim 3. Rebooting MARSSx86 using the last created checkpoint: qemu/qemu-system-x86_64 -vnc :10 -m 4096 -loadvm bzip2 -simconfig simconfig.cfg -hda /opt/images/ubuntu-natty.qcow2 where simconfig.cfg file have the contents exactly as shown bellow: -simpoint /opt/simpoints/401.bzip2/t.simpoints -simpoint-interval 100M -simpoint-chk-name bzip2 Do you have any idea about what might be wrong? Thanks in advance, George
