Hi, Zaheerul Arefeen wrote: > what would be solution for my problem? I dont like to You need to pass the location of the configured kernel source tree (or configured kernel headers) when configuring GM with the "--with-linux=<path>" flag, the default location being /usr/scr/linux. If you compile GM for a given kernel, it will not work on a different one (it may be safe, but there is no way to know for all kernel versions, so it is restricted by precaution). So, if your front-end does not have Myrinet, that's easy: either mount or copy the 2.4.18 kernel source tree on the head node and use it to compile GM: it will work on all of the compute nodes. If the front-end does have Myrinet, you can either get the front-end and the compute nodes with the same kernel (not only versions, but some settings like bigmem, smp, etc, must be the same) and you build one GM for all, or you build one GM for the front-end and one for the compute nodes passing the right kernel source location at configure.
