Bug for balanceddatapartition

Describe the bug
I tried to use Release/balanceddatapartition to partition the dataset by the following command.
./balanceddatapartition -d 420 -v float -f XVEC -i msong/msong_base.fvecs -c 200 -m L2
Then, I got the following output.

[1] Using AVX512 InstructionSet!
Authorization required, but no authorization protocol specified
Authorization required, but no authorization protocol specified

[1] rank 0 init centers
[server:3290477] *** Process received signal ***
Segmentation fault (core dumped)

After add -t 1, the I got more error messages.

I am not sure if I can use the Release/balanceddatapartition program for partitioning the data. Or can you please offer me some alternative choices to partition the dataset. The python binding seems to work well.

Thank you.

Start by reproducing the reported command with Release/balanceddatapartition, first with the default thread count and then with -t 1, and inspect the recorded segmentation-fault stack trace. Compare this behavior with the Python binding, which the report says works. Done means identifying and fixing the crash or documenting a working partitioning alternative.
