Hi,
first of all, this is a question for the Turbomole Support, so please write an email to turbomole at cosmologic de.
Turbomole 5.10 for IBM/Linux has been compiled and tested on a SLES 9 machine, and IBM's own libraries like ESSL, PESSL, POE, ..... are not included in the binary distribution.
If IBM has no official SLES 10 Myrinet drivers, I guess that they would not install SLES 10 on a cluster with Myrinet - so what interconnect does your IBM have?
Regards,
Uwe
