#
# Troubleshooting
#
# For automatical checking of order of the output elements in
# the pipelined sorters stxxl::stream::sort and stxxl::stream::merge_runs
# use -DSTXXL_CHECK_ORDER_IN_SORTS compile option
#
# if your program aborts with message "read/write: wrong parameter"
# this could be that your kernel does not support direct I/O
# then try to set it off recompiling your code with option
# -DSTXXL_DIRECT_IO_OFF (the libs must be also recompiled)
# The best way for doing it is to modify the STXXL_SPECIFIC
# variable (see above).
# But for the best performance it is strongly recommended 
# to reconfigure the kernel for the support of the direct I/O.
