mpconstest Command-Line Syntax

tst=Cons1|Cons2|Cons3|Cons4| Cons5|Cons6| Cons7|Cons8| Cons9|Cons10| Cons11|Cons12| Cons12|Cons13| Cons14|Cons15| Cons16|Cons17

Range of choices available between cons1 through cons17 subtests. 

itm=number

Sets the number of times the test is allowed to time out. Default is 1. Note that each timeout occurs after a greater amount of elapsed time than the previous one. That is, if the first timeout occurs after T units of time, the second occurs 2T after T, and the third occurs 3T after 2T.

lck

Locks Buffer in Memory. Default is not locked. Locking the buffer in memory will disable COMA (Cache Only Memory Architecture). 

a

Enables atomic mode. Uses the atomic instruction swap 

b

Enables byte mode. Uses byte instructions to load and store.  

c

Generates a core file. Exits in case of unexpected signals. 

e

Disables the external cache. 

h

Prints usage message. 

loops=number

Sets the number of loops for the iterations. Default is 5. 

memsize=memsize

Selects the memory size, in Megabytes, for the shared buffer. Default is 128. 

wait=cpucount

Forces CPU 1 to write first if the number of CPUs is less than cpucount.

passes=passes

Selects the number of passes. Increasing the number of passes increases system stress. Setting the number of passes to 0 will cause the test to run in an endless loop. Passes can only be set to 0 in command line mode, not from the GUI. Default is 1. 

r

Enables Reverse mode. Traverses the shared memory buffer in reverse. 

t

Enables Trigger. Sends an interrupt signal to all processors when one processor detects a failure. 

x

Enables Prefetch. Sets prefetch for read and write. 

y

Enables Offset. Specifies an offset of line size between successive writes.  

i

Enables Immidiate Mode. Not suppored for subtests cons1, cons2, cons3, cons15, and cons 17. 

q

Enables Random Mode. 

seed

Sets a random number seed to the user specified value.
