I do not remember explicitly this Intel + Intel MKL ScaLAPACK issue on CRAY... Did you try Intel + LibSci? PGI + CRAY LibSci works perfectly. I do not see any potential problem to use LibSci also with Intel…

A member of CSCS staff also managed to compile with both PGI and CCE, and his PGI build was slightly faster than my CCE. So, if you are familiar with PGI, you should probably stick to that.

Do you have the make.sys used by CSCS people? Or can you put me in contact with the guy who managed to compile the code? The fact is... if they improvements comes from special flags or linking sequence we can basically include them in the configure and…  it's a win/win!

Rosa is back in production. i can try some combination during this week…

Cheers,
F.
