Monitoring Parallel Jobs

What is the best Tool for monitoring parallel jobs?


Background::
Running a parallel job (using OpenMP).
The jobs is designed to use all four processors
(it echos back the thread numbers ranging from 0 to
3).

"syd" shows (in Barchart mode) that the job
is taking up around 90% of CPU for this particular
user, but that doesn't seem right, in particular since
in the "bar graphs" of syd all CPU is busy (indicating
that the job indeed uses all processors).

Using "ps ux" the jobs shows up using around 300% of
CPU, which seems to indicate that multiple processors
are used.

Likewise, xload goes up by four units rather than one,
which also seems to indicate that four threads are
using the four processors in parallel.

Is there any tool other than syd that can be used to
monitor parallel jobs?
