Could you please explain this a little more? What differences are there
between defining it in the complex or in the sge_request?

honestly, I did not know that there was a man page for sge_pe (I
did't think about it). thanks a lot.
I have to configure MPI environment, if I have any other question I'll
come back. thanks.

h_rt, if you request a resource for a time, I want SGE to take into
account all the time, not just the cpu time (I don't really care if
your job is efficient or not).

ACCT_RESERVED_USAGE
If this parameter is set to true, the usage of reserved
resources is used for the accounting entries cpu, mem and io instead of the
measured
usage.
Two question here:
1.-) if set to false, the usage is not used but the measured?
2.-) It talks about "reserved resources", but -l talks about
"requested" resources. So, do I have to force users to reserver
requested resources?

Many thanks for your replies Reuti,
