Compilation FAQs
How do I compile my old 32-bit code under the new 64-bit environment?
You should be able to recompile your code using the same compiler as you did on the old cluster. However, some compiler options may need to be 'tweaked'. For starters try using as few options as possible. For example, remove optimizations, check and debugging options. Investigate possible data alignment issues. If the code worked before, you shouldn't be too far from a solution. For new public domain codes, the task can be a much larger effort.
Where can I find some C++ info?
There are many internet resources. Try the compiler vendors first. Otherwise try:
C++
What recourse do I have if my old 32bit codes can't run on the cluster?
Contact us for access to a legacy 32bit linux node(iridium.uit.tufts.edu) with gcc compilers.
