Source files in accessible on PVFS2 filesystem using icc 10.X

[mtmoore]

I opened a case, 607577, related to problems reading source files when using icc from a PVFS2 filesystem. I was hoping to receive some adiditional information regarding the case.

Currently, I am able to compile using icc when reading source files from a PVFS2 filesystem using Intel Compiler 11.1 however version 10.1 and 10.0 exit with errors indicating they were unable to read the source files. I have no problems in any version using the fortran compilers. The last information I received indicated this was a 'feature request' in future versions.

Can someone please provide an update on the case and information regarding what about the filesystem is causing icc problems in the earlier versions.

Thanks,
Michael

You indicated that 11.1 is working with PVFS. Is there any reason to use Older version of the compiler?

The Intel compiler is not validated using PVFS file system. The compiler is validated using Linux file system and the specific Linux versions are mentioned in compiler "Release Notes".

A bleeding-edge filesystem implementation such as PVFS2 may have bugs that become exposed by running a particular software package, e.g., ICC10.x.

If it is the case that ICC10.x works error-free on, say, EXT2 but fails on PVFS2, I'd consider that an indication of PVFS2 failing to maintain compatibility with standard Linux filesystems, and the problem is one of debugging PVFS2.
