on cygwin running on localhost on standalone computer I noticed a large time discrepancy when the computer is connected or not to the network.
Physical Connected: marco@MARCOATZERI /pub/devel/openmpi/examples $ time mpirun -n 4 ./hello_c.exe Hello, world, I am 0 of 4 Hello, world, I am 1 of 4 Hello, world, I am 2 of 4 Hello, world, I am 3 of 4 real 1m14.568s user 0m1.496s sys 0m2.602s NOT connected (all interface down) $ time mpirun -n 4 ./hello_c.exe Hello, world, I am 0 of 4 Hello, world, I am 2 of 4 Hello, world, I am 1 of 4 Hello, world, I am 3 of 4 real 0m3.323s user 0m1.480s sys 0m2.118s I guess the 1 minute is due to some time of timeout. Is such delay present on any other platform ? Any workaround to remove it ? Regards Marco
