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
This will show each core as a separate CPU
