Hi Pritha, Just to clarify, the -caches and -l2cache flags are not used by Ruby. Also you might want to specify the -num-dirs=4 to create a symmetric system, but if you don't, I believe the default of 1 directory should still work. There are a couple things I would like you to try:
1. Could you compile the m5.debug version of MOESI_hammer and see if you can gather any additional information. 2. Could you run with the classic memory system using fs.py and timing mode and see if you encounter problems.

I'm happy to help you out and determine what the problem may be. However, be warned that I might not be able to immediately create and push in a fix. Could you send me the specific command line you ran? Also could you confirm that the MOESI hammer protocol with 4 processors works and that your problem is isolated to the MESI CMP directory protocol.

It seems to be functioning properly with 1 processor and 2 processors. But when I tried to run 4 processors, am getting the error: SMP: Processor 1 failed to start. SMP: Processor 2 failed to start. Therefore only 2 processors are getting launched, and even after that its not executing properly, am getting the following error repeatedly after sometime hda: dma_timer_expiry: dma status == 0x64 hda: DMA interrupt recovery hda: lost interrupt Could someone help me regarding this? I am not sure where to look into for trying to understand the reason of the problem...
