many thanks, you were right.

That's the current state:

I now call R with:
taskset 0xffffffff R
which allows all cores to be used by R.
Actually I set
alias R='taskset 0xffffffff R'
The combination of a snow (socket) cluster and Sys.setenv 
(`GOTO_NUM_THREADS`=XXX)) works as expected and allows to change the 
number of workers and adjust the number of threads used by the BLAS 

Using multicore, one core per mc.cores is used as the name of the 
parameter suggests.

Best and many thanks,
