Why does it say ERROR: Copying executable failed?
I got this strange, difficult to reproduce message: ERROR: Copying executable to run directory FAILED or ERROR: Copying executable from build dir to exe dir FAILED! along with the bit about hashes not matching from the previous question. Why? a. Perhaps you have attempted to build the same benchmark twice in two simultaneous jobs. On most operating systems, the SPEC tools don’t mind concurrent jobs. They use your operating system’s locking facilities to write the correct outputs to the correct files, even if you fire off many runspec commands at the same time. But there’s one case of simultaneous building that is difficult for the tools to defend against: please don’t try to build the very same executable from two different jobs at the same time.
