Hi, I am new to linux cluster environments. Recently we have ported some C programs to a linux cluster of 3 nodes running the Red Hat Scyld OS. Currently, our programs do not employ any special parallel libraries like PVM or MPI. Does Scyld parallelize the programs by default, atleast upto some extent without using the specialized libraries? Can I still use GCC -O / -O1 / -O2 .. flags to compile these files. Does this still increase the performance or does this have any side effects? Could someone please help me out. Thanks, Sashi. __________________________________________________ Do you Yahoo!? HotJobs - Search new jobs daily now http://hotjobs.yahoo.com/
