BAH, The error persisted when doing the test to /tmp/ (local disk) I rebuilt the library with the same compiler and all is well now. Sorry for the false alarm. Thanks for the help and ideas Jeff. Brock Palen www.umich.edu/~brockp CAEN Advanced Computing XSEDE Campus Champion bro...@umich.edu (7

Brock and I chatted off list. I'm unable to replicate the error, but I have icc 14.0.1, not 14.0. I also don't have Lustre, which is his base case. So there's at least 2 variables here that need to be resolved. On Jan 9, 2014, at 11:46 AM, Brock Palen wrote: > Attached you will find a small

Afraid I don't have access to Intel compilers (oddly enough), but my immediate thought would be that there is some variable size difference - possibly a default change between 64 and 32 bit for "int"? Your output offset just looks to me like you wrapped the field. I believe the MPI interfaces a

I never saw any replies on this. Has anyone else been able to produce this sort of error? It is 100% reproducible for me. Brock Palen www.umich.edu/~brockp CAEN Advanced Computing XSEDE Campus Champion bro...@umich.edu (734)936-1985 On Jan 9, 2014, at 11:46 AM, Brock Palen wrote: > Attached

Attached you will find a small sample code that demonstrates the problem but ether MPI_File_seek() or MPI_File_get_position() is screwing up on me. This only happens with this version of the intel compiler: Version 14.0.0.080 Build 20130728 You can compile and run the example with: mpicc -g -
