Hi all, I've got some very basic questions about building Julia from source on an hpc cluster. I got it to build fine a month ago, but now the makefile changed. I was partially succesful this time as well (my test runs), but some strange things happen and there's a lot of stuff in that makefile I dont' understand.
- I can't get Make.user to work. My understanding was that i `cp Make.inc Make.user`, then change the options I want changed, then `make`? Nothing happens. Do I have to delete Make.inc after having made my copy? - I needed to set `JULIA_CPU_TARGET=core2` when I last got it to build. The cluster is built out of several different CPU types, so not setting this resulted in target mismatch errors. I can't find that line anymore in the current Make.inc, so I changed https://github.com/JuliaLang/julia/blob/master/Make.inc#L345 from JULIA_CPU_TARGET ?= native to JULIA_CPU_TARGET = core2 - Is this still recommended practice or should I not touch this at all? - the openblas default build failed. I set this: - OPENBLAS_DYNAMIC_ARCH=0 - OPENBLAS_USE_THREAD=0 - OPENBLAS_TARGET_ARCH=BARCELONA - It says in the trouble-shooting section on https://github.com/JuliaLang/julia/readme.md that a possibel solution to problems is to set the last variable to BARCELONA for AMD and NEHALEM for Intel. What if I have both CPUs? Does it matter? - With those settings it compiles, and my little test script runs. However, I get this error/warning from all workers: - ./julia: /lib64/libz.so.1: no version information available (required by /data/uctpfos/git/julia/usr/bin/../lib/libjulia.so) - In case this is helpful, my `cat /proc/version` is: - Linux version 2.6.32-279.19.1.el6.x86_64 ([email protected]) (gcc version 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC) ) #1 SMP Tue Dec 18 17:22:54 CST 2012
