Hello, This is Lei Yang (at Guang Zhou, China) I am trying to install MPICH or MPICH2 on our cluster, but many errors came up, please help me!! attached c.txt, m.txt, mi.txt are for configuration, make and make install results. (i has been trying to install this for days, please do help!!~) I think the main issue is that it didn't pass configure test, and showed 'can't find -lfmpich' I use intel fortran compiler. my .bashrc file is like this export F90=/opt/intel/fc/10.0.023/bin/ifort export FC=F90 export CC=gcc export F77=F90 and my cluster information is: Processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Xeon(R) CPU E5430 @ 2.66GHz stepping : 10 cpu MHz : 2660.002 cache size : 6144 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 4 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush d ts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm constant_tsc pni monitor ds_cpl vmx est tm2 cx16 x tpr lahf_lm bogomips : 5323.69 clflush size : 64 cache_alignment : 64 address sizes : 38 bits physical, 48 bits virtual power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Xeon(R) CPU E5430 @ 2.66GHz stepping : 10 cpu MHz : 2660.002 cache size : 6144 KB physical id : 0 siblings : 4 core id : 2 cpu cores : 4 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush d ts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm constant_tsc pni monitor ds_cpl vmx est tm2 cx16 x tpr lahf_lm bogomips : 5320.00 clflush size : 64 cache_alignment : 64 address sizes : 38 bits physical, 48 bits virtual power management: processor : 2 vendor_id : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Xeon(R) CPU E5430 @ 2.66GHz stepping : 10 cpu MHz : 2660.002 cache size : 6144 KB physical id : 0 siblings : 4 core id : 1 cpu cores : 4 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush d ts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm constant_tsc pni monitor ds_cpl vmx est tm2 cx16 x tpr lahf_lm bogomips : 5320.06 clflush size : 64 cache_alignment : 64 address sizes : 38 bits physical, 48 bits virtual power management: processor : 3 vendor_id : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Xeon(R) CPU E5430 @ 2.66GHz stepping : 10 cpu MHz : 2660.002 cache size : 6144 KB physical id : 0 siblings : 4 core id : 3 cpu cores : 4 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush d ts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm constant_tsc pni monitor ds_cpl vmx est tm2 cx16 x tpr lahf_lm bogomips : 5320.01 clflush size : 64 cache_alignment : 64 address sizes : 38 bits physical, 48 bits virtual power management: Thanks very much!!! ~ ------------------------------------------------------------ LED The South China Sea Institute of Oceanology, CAS Guangzhou, China, 510301 Tel:86-20-89023199
