I have a CFD code that does a lot of element-wise (A(i,j)*B(i,j)) math with large arrays. roughly 500x500 R*8s, with most sections of the code using a half dozen of these (1.5MB) arrays at a time.

To clean up the code, and in a naive hope that IFC would figure out the best way to manage the work, we vectorized most of the code.

VTune still shows a lot of time wasted with various stores, even with higher optimizations.

I tried to compile and linkzgetrsx.f in the lapack example. When I used
link zgetrsx.obj mkl_s.lib
there was an error message:

zgetrsx.obj : error LNK2019: unresolved external symbol _X04DBF referenced in function _MAIN__
zgetrsx.exe : fatal error LNK1120: 1 unresolved externals

Do you know what's wrong?

We recently "upgraded" to MKL v7.2 and our application no longer runs on the Celeron CPU. Is this cpu no longer supported? Which cpus are supported? Is there by chance a simple C-based method for checking a given machine that it has capable hardware?

Sir,
I am trying to install mkl non commercial version (l_mkl_p_7.2.008.tar) in Red Hat Linux (Enterprise). When the tar file is unzipped install.sh file is not found.Only two files are obtained (an executable file install 66mb and an mkl_lisence file) How can I install mkl without install.sh file, or is it the problem of downloading or unzipping?
