Sadly, none of these solutions worked for me on my RPi: - pi@raspberrypi ~/openmpi-1.6.3/opal/asm $ make CCASFLAGS=-mcpu=arm1176jzf-s CPPAS atomic-asm.lo atomic-asm.S: Assembler messages: atomic-asm.S:7: Error: selected processor does not support ARM mode `dmb' atomic-asm.S:15: Error: selec

That's a weird one -- it looks like having too many open files on your system is causing a cascading set of failures. Are you saying that your program runs for a while and then on iteration 32, it fails with errors like this? If so, I'd like for a file descriptor leak in your program. On J

Mmmm. Let's rope in our ARM expert here... Leif, do you know what the issue is here? On Jan 3, 2013, at 4:28 AM, Lee Eric wrote: > Hi, > > I am going to compile OpenMPI 1.6.3 in Raspberry Pi and encounter following > errors. > > make[2]: Entering directory `/root/openmpi-1.6.3/opal' > CC
