--- Comment #8 from Jure Pečar <jurij.pe...@embl.de> --- Keen eyes in easybuild community noticed that cpuid.d uses ubyte for numcores in a couple of places. For example, function getcacheinfoCPUID4 uses uint for numcores, but function getAMDcacheinfo uses ubyte. It also doesn't differentiate between cores and threads so I assume it walks all logical cpus there in the loop on lines 633-641. Bergamo has 128 cores, 256 threads, ubyte rolls over and then on line 659 you divide something by numcores. Boom. To test this hypothesis, I disabled SMT on one of the Bergamo nodes. Indeed, LDC then works as expected: # ldc2 Error: No source files So I'd say the fix is to just s/ubyte/uint/g on cpuid.d. And check if you do any similar things elsewhere. Thanks, --
