We recently added a Dell Poweredge R420 to our compute server mix. Because of the newer hardware we had to install Windows Server 2012 STD. To which we added the HPC addon to make it similar to our other compute servers running Windows 2003 Compute Cluster Edition.
Our existing software built with Intel Visual Compiler XE 18.104.22.168 runs without problems on the older setup. But on the new configuration we get an IO error at what seem to be random (maybe load dependent). If the application writes a very large file followed by a close then open it again we get an IOSTAT=30. The writes are to a local raid 1 disk with a controller with 1GB cache. Which is similar to our older compute servers.
Is there a compatibility issue between Visual Fortran and Windows Server 2012.
