[m5-users] AttributeError: 'function' object has no attribute 'cpu'
Hi guys, I am interested in M5 for architecture simulating. I tried to build an ALPHA_FS version of the M5 simulator in my x86-64 computer, downloaded and installed the full-system binary and disk image files. Then I passed all the quick tests. The troubles arose when I tried to run the full-system using fs.py in m5/configs/examples. Can any of you give me some hints please? Or, should I do some work to modify the default fs.py to generate a new one before any simulating job? Thank you very much.

This bug was in the development repository briefly but has been fixed. If you pull the new changes it should go away.

[m5-users] Linux v2.6.27 limits the number of cores to 32
Hi, I am running into an issue with running applications in ALPHA_FS on more than 32 cores. The cores of index greater than or equal to 32 sit and spin, as indicated by their uniformly small number of committed instructions, during parallel sections of benchmarks with more than 32 threads. The problem exists in kernel v2.6.27, which we built using the method described on the M5 site. I have done some testing, and I have identified that our kernels, v2.6.13 and v2.3.16, both schedule threads on all 64 cores. Further, the file, `.config.m5' contains a line to configure the maximum number of cores, which is different for different linux versions: 2.6.13, 2.6.16: CONFIG_NR_CPUS=64 2.6.22, 2.6.27: CONFIG_NR_CPUS=32 I've tried building a few different versions, and each asks Use M5 64 Processor Tsumani Modification (BIG_TSUNAMI) [Y/n/?], but setting this doesn't seem to have an affect on kernels 2.6.22 or 2.6.27. The config script restricts the CONFIG_NR_CPUS flag to 2-32 cores for kernel versions 2.6.22 and 2.6.26. Can someone give some insight into how to fix this so the v2.6.27 scheduler works with 64 cores?
