- debugLvl :: Int
Debug level, a number defined in module
Control.Parallel.HdpH.Internal.Location.
Default is 0 (corresponding to no debug output).
- scheds :: Int
Number of concurrent schedulers per node. Must be positive and
should be <=
to the number of HECs (as set by GHC RTS option
-N
). Default is 1.
- wakeupDly :: Int
Interval in microseconds to wake up sleeping schedulers
(which is necessary to recover from a race condition between
concurrent schedulers). Must be positive.
Default is 1000 (corresponding to 1 millisecond).
- maxHops :: Int
Number of hops a FISH message may travel before being considered
failed. Must be non-negative. Default is 7.
- maxFish :: Int
Low sparkpool watermark for fishing. RTS will send FISH message
unless size of spark pool is greater than maxFish
(or unless
a FISH is outstanding). Must be non-negative;
should be <
minSched
. Default is 1.
- minSched :: Int
Low sparkpool watermark for scheduling. RTS will respond to FISH
messages by SCHEDULEing sparks unless size of spark pool is less
than minSched
. Must be non-negative; should be >
maxFish
.
Default is 2.
- minFishDly :: Int
After a failed FISH, minimal delay in microseconds before
sending another FISH message; the actual delay is chosen randomly
between minFishDly
and maxFishDly
. Must be non-negative; should
be <=
maxFishDly
.
Default is 10000 (corresponding to 10 milliseconds).
- maxFishDly :: Int
After a failed FISH, maximal delay in microseconds before
sending another FISH message; the actual delay is chosen randomly
between minFishDly
and maxFishDly
. Must be non-negative; should
be >=
minFishDly
.
Default is 1000000 (corresponding to 1 second).
- numProcs :: Int
Number of nodes constituting the distributed runtime system.
Must be positive. Default is 1.
- networkInterface :: String
Network interface, required to autodetect a node's
IP address. The string must be one of the interface names
returned by the POSIX command ifconfig
.
Default is eth0
(corresponding to the first Ethernet interface).
