When I start the default demo database (or a new created one) process on Windows XP, the following messaged appears in the command window :
# Serving databse 'demo', using 1 thread
 
Does it mean the whole database process is single-threaded?
The following section in the monetdb5.config file shows we can config multiple threads
 
# Mserver 5 recognizes a series of command line names instead:
# --threads ( 1 | PARMASK)
# --memory (MEMMASK )
# --properties (CHECKMASK | PROPMASK | BATMASK )
# --io (IOMASK | PERFMASK )
# --transactions ( TMMASK | DELTAMASK | TEMMASK)
# --modules (DLMASK | LOADMASK)
# --algorithms (ALGOMASK | ESTIMASK)
# --xproperties (XPROPMASK )
# --performance (JOINPROPMASK | DEADBEEFMASK)
 
What does 'parmsk' mean, and how to config monetdb to use multiple threads?
