The physical memory of the guest is allocated from the memory on the
host. If you're on a 32 bit machine you definitely can't allocate 4GB
of memory since that's the whole address space, and on a 64 bit
machine you may not be able to depending on how much memory/swap you
have. Static linking is only a requirement for SE mode. I don't know
anything about running SPEComp under gem5 so I don't know whether it's
known to work or not.

Hi Gabe,
Whenever I attempted to run SPEComp benchmark (e.g., 310.wupwise_m), the
process always got killed ("Killed" was shown in my telnet terminal). I
think the problem is that the memory size of ALPHA_FS is too small (default
is 128MB). I tried to increase the size but the size cannot be as large as
4GB (512MB is okay though). Have you seen this kind of problem before? I
noticed that someone run the test on ALPHA_SE with static loading. Is this
the only way I can do (is it impossible in ALPHA_FS?)
Thanks a lot in advance.

Subject: Re: [gem5-users] running SPEComp on ALPHA_FS
Are you sure the simulator is actually using the image file you modified?
You might want to double check that.

Dear all,
When I tried to run SPEComp2001 on ALPHA_FS mode, I was stuck at how
to add the benchmark to the image. Actually, I have created an empty
image (120M, named "linux-latest-specomp.img") by gem5img.py. And I
did the following things to add the benchmarks.
1. Copy all directories in the original "linux-latest.img" to
"linux-latest-specomp.img".
2. Copy the "alphaev67-unknown-linux-gnu/lib" directory from the
cross
compiler to the "/lib" directory in "linux-latest-specomp.img".
3. Copy the SPEComp benchmark directory (including 8 benchmarks with
exe and data subdirectory) to the "/benchmarks" in
"linux-latest-specomp.img".
4. Unmount "linux-latest-specomp.img".
After the above steps, the benchmarks should be added to the image.
Unfortunately, when I started the simulator, I didn't see the new
directory under "/benchmarks". I also tried to paste the SPEComp
benchmark to the root directory. But I failed again. Anyone can help me to
fix it?
Thank you very much!
