thank you for your timely response and for the good news regarding Xeon 3500.
In an attempt to be able to use PAPI for programs running on more than just 4 cores, I will need to install PAPI on a smaller Linux cluster. The processor types vary among the nodes, but they all come down to:
Intel Xeon CPU 3.06GHz with 1.5GB memory (4 CPU cores), cpu family: 15, model: 2
Intel Xeon CPU 3.60GHz with 2.0GB memory (4 CPU cores except one node that has only 2 cores), , cpu family: 15, model: 4
Pentium III 1.4GHz with 0.5GB memory (single CPU), , cpu family: 6, model: 11
I don't know what Linux & kernel version they are running. Looking on PAPI's currently supported platforms, I believe Pentium III will be supported, but I am not 100% sure about the other two Xeon models. Do you know if PAPI supports these models?
