Hello all ,

I am trying for simulating  for   I  NUCA protocol. I use

Error: Could not open network file:

Network_Files/NUCACOL_Procs-8_ProcsPerChip-8_L2Banks-256_Memories-8.txt
Probably no network file exists for 8 processors and 8 procs per chip

There is already a file in  /home/nilufar/gems/ruby/network/simple/Network_Files//NUCACOL_Procs-8_

ProcsPerChip-8_L2Banks-256_Memories-8.txt and it contains some valid data. But I can not understand why it is showing error. Please help me. Thanks a lot!

Thanks!
