Dear all, <div>I've also started getting a lot of IOTK errors recently using the CVS version. </div><div>I've got two possible candidates, </div><div>1)highly asynchronous file system (i.e. a parallel system that is not robust in the sense of NFS, and highly overloaded) </div>
<div>2) a conspiracy going on with the newest intel compilers running in an environment that is not-so-new. </div><div>Since this error is annoyingly frequent but not replicable at will, could you please contact me if you are using a asynchronous file system with the compilers you are using? ,</div>
<div>Best,</div><div>Baris Malcioglu</div><div> P.S. The parallel file systems optimized for performance tend to be asynchronous, full list can be found here:</div><meta http-equiv="content-type" content="text/html; charset=utf-8"><div>

no. This is the fix for a very specific case, and the only one I remember in<br>
which an error was issued by iotk for a good reason (i.e. a variable was<br>
written with one name and read with another). All other instances of iotk<br>
errors I remember are related to miscompilation.<br>
<br>
Try first of all to compile iotk with reduced optimization (e.g. using<br>
$(MAKE) FFLAGS="$(FFLAGS_NOOPT)" )<br>
