Hi I've tried the code here and then I had a strange issue. My computer is : Linux 2.6.26.6-79.fc9.x86_64 SMP Athlon 64 X2 Dual Core 4000+ When i set everything and tried to run the code, (also in compiling and linking stage) i got no errors. Here is the output: 0 : NCPUt= 2 0 : NTHRt= 2 0 : NPRt=1 O : hello multicore user! I am thread 0 out of 1 do you have any idea? Thanks »
