Option 

Description 

Test Name 

Selects the subtest to be run. 

Number of Timeout Iterations 

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.

Lock Buffer 

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

Atomic Mode 

Uses the atomic instruction swap. Default is disabled. 

Byte Mode 

Uses byte instructions to load and store. Default is disabled. 

Immediate Mode 

Supports all subtests except cons1, cons2, cons3, cons15, cons16, and cons17. 

Random Mode 

Enables Random Mode. 

Reverse Mode 

Traverses the shared memory buffer in reverse. Default is disabled. 

Prefetch Mode 

Sets prefetch for read and write. Default is disabled. 

CoreFile 

Generates a core file. Exits in case of unexpected signals. Default is disabled. 

Ecache Disable 

Disables the external cache. Default is enabled. 

Trigger 

Sends an interrupt signal to all processors when one processor detects a failure. Default is disabled. 

Offset 

Specifies an offset of line size between successive writes. Default is disabled. 

CPU Wait Count 

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

This option is not supported with subtests cons15, cons16, and cons17. 

Number of Loops 

Selects the number of test loops. Default is 5. 

Number of 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. 

Memory Size 

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

Random Mode Seed 

Sets random number seed to a user specified value. Selects a random number seed by default.
