hi,
We are using 64-bit machine with 16GB memory and SPEC CPU 2000 benchmarks.
Please read the part of the configuration file attached below, My
understanding is that in the configuration file we have total 10GB physical
memory for one simulation with 8-core (1-thread per core) , am I right?
I have checked that memfree+swapfree in our system is about 14GB memory
(13144704 KB + 2031608 KB), which is greater than 10GB. It seems that there
is enough memory, but the error message is "out of memory". Do you think
anything wrong with the configuration setup itself?
===================================================================================
np = 8
num_thrds_per_cpu = 4
system = System(cpu = [CPUClass(cpu_id = i) for i in xrange(np)],
physmem = PhysicalMemory(range = AddrRange("10GB")),
membus = ToMemBus(), mem_mode = test_mem_mode)
====================================================================================
