Good news: Radiance can be compiled on: Intel C++ Compiler XE version 12 Update 5 Linux version (released 29 of July). (Please make sure to download this version as the Parallel processing suite contains an older version, that probably does not work). The following line in the makefile Case 2: set extras=CC=gcc has to be changed into set extras=CXX=icpc (This invokes the Intel C++ compiler (icpc), the Intel C compiler (icc) doesn't work (segfaults)). For compile options I used -O3 and I ran Mark Stock's benchmark with rpict. (I still need to try all other programs). The time needed was 21m 4.674s. (System Intel 2600K @3.8GHZ, 64-bits Linux (Kubuntu)) Other Compilers able to compile Radiance: Note: I only tried the C Compiler, maybe the C++ compilers perform even better. Oracle Solaris Compiler Suite v12.2 with -O5 rpict time 20m 59.109s AMD Open64 Compiler v4.2.5.2 Generates internal compiler error with anything higher than -O1 (filled in a bug report for AMD to fix). rpict time 40m 33.7s The Solaris Compiler seems to be a little bit faster, but maybe some extra optimizations can be set for the Intel compiler. Also I have to compare these results with GCC and maybe the PGI compiler. Best Regards, Guy
