We normally install and run the Intel MPI compiler for Linux on RedHat systems. When building and installing the compiler for a SLES 10.2 system, we encountered the following warning message:
WARN: Either the device /dev/shm was not found on your system or a mount entry wasn't found for it in the /etc/fstab file. Before using Intel MPI Library, Development Kit for Linux* OS, please make sure this device is present.
Sure enough, no mount point for /dev/shm is defined in /etc/fstab (RedHat defines a mount point like this: tmpfs /dev/shm tmpfs defaults 0 0). The simplest test on the SLES 10.2 system seems to run (I'm only a sysadmin, so my knowledge of MPI programming is very limited). However, this does not give me a warm feeling (a real MPI pgm might notice the difference).
My question is: has anyone installed the Intel MPI compiler on SLES 10, and if so what (if anything) has to be done to define the /dev/shm mount point?
Thanks in advance
