Dear MolPro developers,
I seem to be not able to run molpro on more than 32 processor (node) on a
cray XT4 system. Am I hitting some kind of ceiling in number of processors
for particular type of job?
Here is some of the relevant information:
cpu : Opteron 2300.000 MHz
FC : ftn
FCVERSION : 9.0
BLASLIB : -lacml
id : lbl
64 such entries...
ga_uses_ma=false, calling ma_init with nominal heap.
GA-space will be limited to 8.0 MW (determined by -G option)
MPP tuning parameters: Latency= 0 Microseconds, Broadcast speed= 0
default implementation of scratch files=sf
Variables initialized (631), CPU time= 0.02 sec
Commands initialized (426), CPU time= 0.01 sec, 469 directives.
Default parameters read. Elapsed time= 0.30 sec
This is where it gets stuck/Hang
These are message on the standard output
ARMCI configured for 64 cluster nodes. Network protocol is 'PORTALS'.
could not unlink file prepin00025079
could not unlink file prepin00020843
could not unlink file prepin00020785
Any help will be greatly appreciated.
