P.S. A lot of other builds would have failed using today's timeout. Check for example build #176 and #177 of the Nightly (end of December)
This makes a lot of sense as these days overlap with the Compiler-Checks run. In fact, almost every time we run Compiler-Checks the Nightly takes more than a day to complete Kind Regards Giacomo > -----Original Message----- > From: Giacomo Travaglini via gem5-dev <gem5-dev@gem5.org> > Sent: 27 January 2021 22:23 > To: gem5 Developer List <gem5-dev@gem5.org> > Cc: Giacomo Travaglini <giacomo.travagl...@arm.com> > Subject: [gem5-dev] Re: Some evidence build times have substantially > increased on Jenkins > > Hi Bobby, > > While I agree there might be something wrong with it, It can be partly > explained with the sheer amount of patches which is being reviewed and > merged in these days.
