Hi everyone,
I can't seem to get the pvmfconfig function to properly return the host and arch arguments using CVF. Does anyone have any ideas on how to get this thing to work properly? At least one member of the PVM team seems to think that this is an issue with CVF and not PVM. Any help greatly appreciated!

Some more information would be helpful, such as:
1. What is PVM?
2. What is pvmconfig?
3. What goes wrong and what do you think should happen?
I see you asked this in the comp.lang.fortran newsgroup and got a response suggesting that it was a bug in PVM. Without any details, though, it's difficult to help.
If you think that CVF is doing something wrong, and are using CVF 6.6B, please write to [email protected] and attach a ZIP archive of a small but complete project that demonstrates the problem, along with a detailed problem description.

Steve,
Thanks for responding. I am sorry that I didn't provide more details. Here are the answer your questions:
1. PVM = Parallel Virtual Machine (http://www.csm.ornl.gov/pvm/pvm_home.html). I'm using 3.4.4 available from Markus Fischer's download page - accessible from pvm homepage.
2. pvmfconfig = a fortran wrapper on a c-language library component of PVM that returns information about the virtual machine configuration to the calling program
3. pvmfconfig appears to work except that two string variables denoted arch (for architecture type) and host (for host name) do not return the proper values.
I just checked the response in comp.lang.fortran provided by Jos Rui. (Thanks for pointing this out - I had requested and was expecting an e-mail response instead of a response to the newsgroup).
After spending some time studying CVF manual regarding mixed language programming and the c code for pvmfconfig, I am in agreement with Jos that the bug lies in the PVM code. I will be forwarding his response and the information from the CVF manual on mixed language programming to the PVM team and see if I can get them to make the fixes and update their binary distribution for Windows. Once I get some feedback from the PVM team, I will post a followup here. Thanks again and best wishes,
John Ross
