IMPORTANT NOTES: ALPHA VS INTEL: --------------- * Although both Intel and Alpha based machines can run NT, remember that these two systems require their own binary format. Thus, you must compile PVM codes for the target physical architecture. * Alternatively, You can run Intel codes on Alpha if you use the fx!32 Windows simulator available from http://www.digital.com/amt/fx32/index.html * An ALPHA binary installshield release of PVM will be available soon. KNOWN PROBLEMS: --------------- * There appears to be a "timeout" problem related to ports on the NT/95/98 systems or with Ataman. One source suggested making all connections non-persistent. The symptom is that it takes some time before a reconnection to a dropped or deleted host is accepted. The error "cannot connect to rsh port ... cannot shutdown rsh client socket" appears in the hoster window during a PVM add command from console. The hoster window is the 2nd DOS type window that opens during PVM add from the console. * Occasionally Windows 95/98 installshield version requires you to recompile before PVM executes properly. Don't have the answer why yet - guess just the magic of MicroSoft... NT / WINDOWS DOCUMENTATION: --------------------------- * Yes, these systems do behave differently than the Unix systems. Thus, much setup and tuning information found in the PVM book does not apply here. We hope to have additional information on this subject in the future. * You can use the LMHOSTS file to aid your machine in "finding" other network machines. This helps PVM as well as other network computer access. ATAMAN INSTALLATION: -------------------- (NT only) Information provided here is for the Ataman package available at http://www.ataman.com (this is a commercial package). - (NT only) Set the environment file to: C:\Program Files\PVM3.4\WIN32\file.env Note that other rshd packages may (or not) require this "help" in setting the PVM_ROOT environment value. This is a result of Ataman's package not using an individual's environment settings (this is discussed in Ataman documentation.) Windows 95/98 does not exhibit this problem as it uses the settings in C:\Autoexec.bat to pickup the environment values. Markus Fischer's RHSD package ----------------------------- This is an alternative package to the Ataman package above. There is a licensing fee associated with this package. Markus was the original person involved in porting PVM to NT. I have not yet had the opportunity to try this package. However, email indicated favorable results. http://www.uni-paderborn.de/cs/getin/getservice.htm LATE BREAKING NT/95/98 NEWS: ---------------------------- * http://www.epm.ornl.gov/~sscott Filename: installation.txt Last Updated: 08-02-1999
