cd NEKCEM/trunk/examples/cylwav (serial) ../../bin/makenek cylwave
cd NEKCEM/trunk/examples/cylwav (parallel) ../../bin/makenekmpi cylwave
cd NEKCEM/trunk/examples/cylwave ../../bin/nek cylwave (serial)
cd NEKCEM/trunk/examples/cylwave ../../bin/nek cylwave #np (parallel)
Note: on Intrepid, #np is the number of node (total number of cores will be #np*4) Note: on Jaguar, do ../../bin/nek cylware #np1 #np1, where #np1 is the actual core number you need, and #np2 is the core number you request from system, which has to be a multiple of 16.
