[parsec-users] Dedup, Memory allocation failed

Dedup simply needs a lot of memory. I'm working on a more efficient version
but for now you should expect to provide a lot of memory. 8 GB works for me.
We will provide a completely overworked version of dedup with PARSEC 3.0.
It'll have a lot of features to make the program more efficient. However,
it's currently not finished.

Are you compiling this for x86_64 perchance? If so, I am seeing the same
error when running dedup in the M5 simulator under X86_FS, so I can confirm
Any ideas what it is? Which memory allocation in the program?

For Dedup, I get a memory error for all of the data sets. Here is an
bash-3.00# ./dedup -i hamlet.dat -o hamlet.out -t 1
PARSEC Benchmark Suite Version 2.1
[HOOKS] PARSEC Hooks Version 1.2
[HOOKS] Entering ROI
[DataProcess] Memory allocation failed.

I increased the memory from 512MB to 1GB and still get the same error.
