Hi all, I am using MKL DSS to solve a sequence of systems of equations in a finite element calculation. The structure of the systems is always the same, and so, DSS_CREATE, DSS_DEFINE_STRUCTURE DSS_REORDER are called only once, while DSS_FACTOR_REAL DSS_SOLVE_REAL are called as many times as needed. The point is that, when running a compilation with Intel Composer version 2013.4.190, everything was OK, and the memory usage remains almost constant during all process. However, after upgrading to version 198, and now to 2013_sp1.0.103, I have verified that for some reason memory usage increases each time DSS_FACTOR_REAL and DSS_SOLVE_REAL are called. It seems that a new memory space is being allocated and nor released each time. Of course that, after a few calls, error “MKL-DSS-DSS-Error, Out Of Memory” happens… If I remember well, a similar problem had occurred in a former version and meanwhile corrected. I already tried to CALL mkl_free_buffers, but the problema remains. Any tip? Thanks!!!! Luis

Luis, I was able the standalone example which shows the problem with DSS API. The memory leak happens during factorization stage. the problem is escalated. the fix of the problem, the mose probably, would be available the next update. I will update this record as soon as this fix would be released.

regards, Gennady
