* [svn-r5729] Purpose:Albert Cheng2002-06-301-6/+14
| | | | | | | | Bring in sync with v1.4 versions that have copyright statements added. Platforms tested: eirene(pp). Only one machine tested because all changes are merely comments.
* [svn-r5456] Purpose:Bill Wendling2002-05-221-7/+11
| | | | | | | | | | Update Description: Updating the source for the PIO performance tests with the current code that's in the V1.4 branch. It includes the newest command-line parameters. Platforms tested: Linux-pp
* [svn-r5367] Purpose:Bill Wendling2002-05-061-0/+2
| | | | | | | | | | | | | | | | | Modification Description: Put some of the variables into the global space so that random functions can access them. (The output and timer variables which point to the output file and timer resp.) Placed the debug level 4 prints into the timer module so that it's easier to automatically put timer start/stop printfs for new timers which are created. Added timers for MPI Time calls (called HDF5_MPI_WRITE and HDF5_MPI_READ). Platforms tested: Linux

| | | | | | | | | | | | | | | | Purpose: Feature Fix Description: Changed so the "pio_perf" module handles creating and destroying the MPI Comm. Worked it so we get the minimum, maximum, and average times over a set of iterations. Solution: Lots. Had to pull the MPI Comm code from the "pio_engine" module and place it in the "pio_perf" module. Then worked on a way to have all processes send their time output to process 0, who collects it and gives back the min, max, and avg times for the iterations. Platforms tested: Linux. Doesn't work if you use more than 1 processor...*hrmph*
* [svn-r4667] Bill Wendling2001-12-041-8/+8
| | | | | | | | | | | | Purpose: Code Cleanup and Feature Add Description: Finally checking in the changes I made to the performance code. It just modularizes it a bit more and performs some more checks, etc. I also renamed the timer functions to be more inline with how other things are named here... Platforms tested: Linux
* [svn-r4608] Bill Wendling2001-11-151-11/+4
| | | | | | | | | | | | | Purpose: bug Fix Description: Changed the code so that if parallel stuff isn't enabled, then we don't compile the parallel code. Solution: Cleaned up the code and put #ifdef's around it checking for parallel flags. Platforms tested: Linux
* [svn-r4592] Purpose:Albert Cheng2001-11-071-0/+70
New addition Description: Initial version of the Parallel I/O performance measurement program. Not fully implemented yet but checking them in before I may destroy them by accident. Don't run this in small file system (like AFS or eirene) since it generates gigabytes test files. Platforms tested: modi4 64bits. It compiled and ran but took a long time because the current test parametes are too "wild".
