<<  Port Validation in HP (formerly Compaq) Tru64, http://bb.cgd.ucar.edu//viewtopic.php?t=77 >>

Message: I have used WACCM (the Whole Atmosphere Community Climate Model,
<br />which is based on CAM) on IBM POWER4 p690 cluster.
<br />
<br />Recently, I have tried to get running the WACCM on Tru64 workstation.
<br />I had no difficulty in compilation and got running the model.
<br />Results on Tru64 workstation did not depend on the number of processors used.
<br />
<br />Then, for validation, I did some perturbation growth tests based on the
<br />documents posted on the CGD homepage.
<br />However, any modifications of optimization levels of compilation on Tru64
<br />workstation gave RMST difference of more than 10^{-2} after two day 
<br />simulation.
<br />
<br />I'd like to know whether the Tru64 (OSF1) is appropriate to run the
<br />CAM or not, since this effort might be useless if the Tru64 has some
<br />problems.
<br />In the past, before CAM, Tru64 (OSF1) was the supported platform.
<br />Why the HP workstation based on Tru64 is not supported any more...?
<br!
  />Did that workstation have some problems?
