Hi, I have a problem running my parallel program using MPICH2. I was wondering if you could help me! When I run mpiexec I get this error: ERROR:Connect on sock (host=ZANA-PC 192.168.1.13 , port=1472) failed, exhaused all end points SMPDU_Sock_post_connect failed. I will appreciate any help, Thanks in advance, Zana, -- ------------------------------------------------------------------------------------------- ------------------------------------------------------------------------------------------- *Zana Karimi* Graduate Research Student, University of Colorado at Boulder Email: [email protected], [email protected]
