Greetings, dealers! I have the following problem with multi-threading. I've followed tutorial 9 and changed my program completely in the same way - I use multi-threading to speed up the assembly procedure. Everything compiles and runs well with 1 or 2 threads. But when I run this problem on our cluster node with 8 cores/threads solution is different!
One could see difference after 3-4 time steps, and it is in the 5-6th digit. Does anybody faced the same problem or have an explanation of what is happening? As I understand nothing should change at all. P.S. When I manually set the number of threads equal to 8 on my dual-core machine I get the same "different" results.
