# When multithreading, OpenBLAS needs to use a memory buffer for communicating
# and collating results for individual subranges of the original matrix. Since
# the original GotoBLAS of the early 2000s, the default size of this buffer has
# been set at a value of 32<<20 (which is 32MB) on x86_64 , twice that on PPC.
# If you expect to handle large problem sizes (beyond about 30000x30000) uncomment
# this line and adjust the (32<<n) factor if necessary. Usually an insufficient value
# manifests itself as a crash in the relevant scal kernel (sscal_k, dscal_k etc)
