installing recent compiler with Co Array fortran on DSM machine

[Izaak_Beekman]

I seem to remember a discussion that the current ifort release supports coarray fortran. Are there special steps one needs to take to install/setup the compiler for use on a distributed shared memory machine? Does this require a certain type of license?

thanks

Z,

Yes, unfortunately you will need a license for Intel Cluster Studio to use distributed memory CAF. Only shared-memory, single-system CAF is supported by the license in the standard compiler product.

There is no runtime check, however. the option -coarray=distributed checks the license for a valid Cluster Studio license at compile time.

distributed requires you use Intel MPI, so that must be installed and working on the cluster prior to CAF use.

A minor correction - the license required is for Intel Cluster Toolkit. Intel Cluster Studio includes this, but it can be purchased separately.

Thanks for the info. I'll discuss w/ the people who make these decisions.
