To specify cores, use `options("mc.cores" = 8)`

Dear Dr. Mike Jiang,

I am Luca Zoccarato, postdoc at the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Berlin.
I am using your R package flowClust to identify coherent populations of microorganisms in environmental samples.
The algorithm is performing very well however I cannot succeed in having it to work in parallel.
I recompile it several times using different BLAS libraries associated with R. R itself is running properly with the additional BLAS library (now I am using openblas and nvblass) but flowClust somehow do not exploit them.
When I run it with K=1, it prompts "Using the serial version of flowClust"; while when set the number of cluster > 1 it uses two CPUs out of 8 that I have.
What can I do to fix this issue?

Best regards,
Luca
