VPR memory corruption while writing packing results (.net) file for large benchmark #78

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Run VPR packing on the linked blif file and architecture

The directrf benchmark seems to pack successfully, but encounters memory 
corruption while writing out the packing results (.net) file.  

Looking at the .net file in the linked archive, you can see that it was only 
partially written, while the log file shows glibc detecting memory corruption.

This may be difficult to debug, since the benchmark requires >64GB of RAM.

Yes, this test case is too big for the machines that I have access to.  
However, the most fragile part of the packer code has been (finally) replaced, 
today, by more robust code that is both faster and uses less memory.  Kevin, 
can you try this out and see if the new code in the trunk takes care of your 
problem?
