result on 32 bit and 64 bit

Hello,

I'm using METIS 4.0 for graph partitioning.
My question is why the result of edgecut number in METIS_PartGraphRecursive function
is different between 32bit run and 64bit run.
I used the same example on the two platforms.

Thanks a lot

This is probably due to the difference in the random number generator between the architectures.

Thanks a lot for this feedback
There is any solution to fix this problem.
I need to have same results on differents
architectures.

Thanks

RE: Not sure. You may want to

Not sure. You may want to use the -seed option to specify the same seed and then hope that the underlying random number generators on these architectures will produce the same sequence of random numbers.
