Your question will probably not receive many answers from this list and should instead be posted on a clustalw list. Further, not knowing anything about your cluster, what you ran, what parameters you ran the command with would make it extremely hard for anyone to make any assumption.
Just a cursory Search online shows that there apparently has been no work on that program in 8 years. Maybe try something else?

Hi,--
I have one bioinformatics question,
At lapaillasse some of us works on a beowulf cluster dedicated to bioinformatics.
So on our cluster we've got some package installed from ubuntu repository.
Testing our package we found something strange.
By comparing clustalw-mpi performance from 1 cpu to 4 cpu, we realized that something goes wrong.
config : clustalw-mpi 0.13 and openmpi 1.5
On a little dataset we found :
On a quadricore 3 gigahertz :
1 cpu = 51 secondes
4 cpu = 1m49 secondes
When you compile clustalw-mpi by yourself everything goes ok.
It is a normal beaviour, or did I miss something??
thx
