Scalable multithreaded system testing tool

A method for testing integrity of data transmitted to and from a target device through a data connection, the method comprising:

• (a) creating one or more test threads, each thread increasing a data load on the data connection;
• (b) creating a performance thread;
• (c) for each test thread,
• (i) generating a portion of the data load on the data connection by repetitively writing blocks of test data patterns to corresponding blocks of memory locations of the target device using a synchronous I/O dispatch method,
• (ii) reading blocks of data patterns from the corresponding blocks of storage locations using a synchronous I/O dispatch method, and
• (iii) comparing the blocks of data patterns read from the target device to the blocks of test data patterns written to the target device to detect data corruptions;
• (d) measuring data throughput with the performance thread while generating the data load with the one or more test threads;
• and
• (e) generating debug information if a data corruption is detected.

A method for testing integrity of data transmitted to and from a target device through a data connection, the method comprising:

• (a) creating one or more test threads that generate a data load on the data connection;
• (b) for each test thread,
• (i) generating a portion of the data load on the data connection by repetitively writing test data patterns to a particular portion of the target device using a synchronous I/O dispatch method,
• (ii) reading data patterns from the particular portion of the target device using a synchronous I/O dispatch method, and
• (iii) comparing the data patterns read from the target device to the test data patterns written to the target device to detect data corruptions;
• and
• (c) generating debug information if a data corruption is detected.

A computer-readable medium containing a program which, when executed on a computer system, performs operations for validating data transmitted between the computer system and a target device through a data connection, the operations comprising:

• (a) creating one or more test threads that generate a data load on the data connection;
• (b) for each test thread,
• (i) generating a portion of the data load on the data connection by repetitively writing test data patterns to a particular portion of the target device using a synchronous I/O dispatch method,
• (ii) reading data patterns from the particular portion of the target device using a synchronous I/O dispatch method, and
• (iii) comparing the data patterns read from the particular portion of the target device to the test data patterns written to the particular portion of the target device to detect data corruptions;
• and
• (c) generating debug information if a data corruption is detected.
