mpqc 2.3.0-1, running on amd64 etch debian, sees only one processor,
while there are two.
I posed the question also to the mpqc list but, in the meantime, I wonder
wether there is anything general to do with debian.
Mother bowrd Tyan K8WE S 2895, two 265 dual opteron, all eight slots of
ram filled (1 GB each)
At computer on:
CPU0=Dual Core amd64 opteron 265
CPU1=Dual Core amd64 opteron 265
All ram detected (also, subsequently, with top command)
However, runs with mpqc (that end successfully) report:
Using ProcMessageGrp for message passing (number of nodes = 1).
Using PthreadThreadGrp for threading (number of threads = 1).
Using ProcMemoryGrp for distributed shared memory.
Total number of processors = 1
As far as I understand, on the general command
$ mpqc filename.inp | tee filename.ou
all available processor should be detected.
What can be done from the debian general point of view of checking
processors?
Thanks for helping.
Cheers

cat /proc/cpuinfo
Thank you (thanks also for another similar message that has gone lost: two
keyboards, too much). Please, see the attached file cpuinfo on the commad
that you suggested. Why three cpu and not two or four?

The first CPU is 0, so you have 0-3 (which is 4)
