Dear All, I am a graduate student working on molecular dynamic simulation. My professor/adviser is planning to buy Linux based clusters. But before that he wanted me to parallelize a serial code on molecular dynamic simulations and test it on a intelcore 2 duo machine with fedora 8 on it. I have parallelised my code in fortran 77 using MPI. I have installed OpenMPI and compiling the code using mpif77 -g -o code code.f and running it using mpirun -np 2 ./code. I have a couple of questions to ask you: 1. Is it possible to use a duo core or any multi core machine for parallel computations? 2. Is that a a right procedure to run a parallel job as explained above?(using mpif77 -g -o code code.f and running it using mpirun -np 2 ./code) 3. How do I know my code is being run on both the processors.(I am a chemical engineering student and new to computational aspects) 4. If what I have done is wrong can anyone please explain me how to do it?
Here is my CPU details: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Duo CPU E6750 @ 2.66GHz stepping : 11 cpu MHz : 2000.000 cache size : 4096 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall lm constant_tsc arch_perfmon pebs bts rep_good pni monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr lahf_lm bogomips : 5322.87 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Duo CPU E6750 @ 2.66GHz stepping : 11 cpu MHz : 2000.000 cache size : 4096 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall lm constant_tsc arch_perfmon pebs bts rep_good pni monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr lahf_lm bogomips : 5319.97 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: Thank you Ramesh
