The following entries are rooted in: `HKEY_LOCAL_MACHINE\SOFTWARE\CSAG\HPVM\'

• `Context Manager\Log file' - Name of CM's event log file (default:`HPVM1.9\bin\fmcm.log')

• `Context Manager\Port' - TCP/IP port to access the local CM (default: 21328)
• `Context Manager\Save file' - File the CM uses to save and restore information about running processes. Not mandatory. (default:`""')
• `Global Resource Manager\Log file' - Name of GRM's event log file (default:`HPVM1.9\bin\fmgrm.log')
• `Global Resource Manager\Name' - DNS Name of machine that runs the Global Resource Manager
• `Global Resource Manager\Port' - TCP/IP port to access the GRM (default: 17997)
• `Global Resource Manager\Save file' - File the GRM uses to save and restore information about running processes. Not mandatory. (default:`""')
• `Giganet\Context Manager\Num Contexts' - Number of FM/Giganet processes that can bind to this network interface (default: 2)
• `Giganet\Context Manager\Num Nodes' - Maximum dimension of Giganet connected cluster (default: 16)
• `Giganet\Context Manager\Num Credits' - Initial number of send credits for each FM/Giganet endpoint (default: 8, must be > 1)
• `Myrinet\Context Manager\Num Contexts' - Number of FM/Myrinet processes that can bind to this network interface (default: 2)
