It will also produce postscript outputs 3 | for each test and leave them in their respective sub-directory. 4 | 5 | It processes the output from an Iozone run. The output from 6 | Iozone that it is expecting is the text output from 7 | the iozone default behavior. (iozone -a, or iozone -az) 8 | 9 | How to produce graphs: 10 | 11 | Generate_Graphs iozone.out 12 | 13 | The gen_graphs script will: 14 | 1. Create the databases for each type of operation 15 | and then processes them with Gnuplot. 16 | 2. It will display each result on the X11 screen, and 17 | also save a copy in postscript in the test sub-directory. 18 | 19 | 20 | Thanks to Yves Rougy for providing the nifty scripts to help 21 | with the plots. 22 | 23 | 24 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | iozone4Android 2 | ============== 3 | 4 | porting iozone to android 5 | 6 | usage: 7 | cd android/ 8 | source ./build/envsetup.sh 9 | lunch xx 10 | cd android/external/ 11 | git clone https://github.com/royzhao/iozone4Android.git 12 | cd iozone4Android 13 | mm 14 | -------------------------------------------------------------------------------- /client_list: -------------------------------------------------------------------------------- 1 | # 2 | # Lines that start with # in column 0 are comments. 3 | # 4 | # There are now two formats supported. 5 | # Format: 3 fields, space delimited. 6 | # Format: 4 fields, space delimited. 7 | # 8 | # Format: 3 fields, space delimited. 9 | # client_name working_dir_on_client path_to_iozone_on_client 10 | # Format: 4 fields, space delimited. 11 | # client_name working_dir_on_client path_to_iozone_on_client path_to_testfile 12 | # 13 | # Example: With two clients (format 3 fields) 14 | # 15 | # client1 /home/user/tmp /home/user/tmp/iozone 16 | # client2 /home/user/tmp /home/user/tmp/iozone 17 | # 18 | # 19 | # Example: With two copies of Iozone on each of the two clients 20 | # (format 3 fields) 21 | # 22 | # client1 /home/user/tmp /home/user/tmp/iozone 23 | # client1 /home/user/tmp /home/user/tmp/iozone 24 | # client2 /home/user/tmp /home/user/tmp/iozone 25 | # client2 /home/user/tmp /home/user/tmp/iozone 26 | # 27 | # Example: With two clients (format 4 fields) 28 | # client1 /home/user/tmp /home/user/tmp/iozone /tmp/foo1 29 | # client2 /home/user/tmp /home/user/tmp/iozone /tmp/foo2 30 | # 31 | # Example: With two copies of Iozone on each of the two clients 32 | # (format 4 fields) 33 | # client1 /home/user/tmp /home/user/tmp/iozone /tmp/foo1 34 | # client1 /home/user/tmp /home/user/tmp/iozone /tmp/foo2 35 | # client2 /home/user/tmp /home/user/tmp/iozone /tmp/foo3 36 | # client2 /home/user/tmp /home/user/tmp/iozone /tmp/foo4 37 | -------------------------------------------------------------------------------- /fileop.c: -------------------------------------------------------------------------------- 1 | /* 2 | * Author: Don Capps 3 | * 3/13/2006 4 | * 5 | * Author: Don Capps (capps@iozone.org) 6 | * 7417 Crenshaw 7 | * Plano, TX 75025 8 | * 9 | * Copyright 2006, 2007, 2008, 2009 Don Capps. 10 | * 11 | * License to freely use and distribute this software is hereby granted 12 | * by the author, subject to the condition that this copyright notice 13 | * remains intact.

First model is a replacement for read() where the async 10 | * operations are performed and the requested data is bcopy()-ed back into the users 11 | * buffer. The second model is a new version of read() where the caller does not 12 | * supply the address of the buffer but instead is returned an address to the 13 | * location of the data. The second model eliminates a bcopy from the path. 14 | * 15 | * To use model #1: 16 | * 1. Call async_init(&pointer_on_stack,fd,direct_flag); 17 | * The fd is the file descriptor for the async operations. 18 | * The direct_flag sets VX_DIRECT 19 | * 20 | * 2. Call async_read(gc, fd, ubuffer, offset, size, stride, max, depth) 21 | * Where: 22 | * gc ............ is the pointer on the stack 23 | * fd ............ is the file descriptor 24 | * ubuffer ....... is the address of the user buffer. 25 | * offset ........ is the offset in the file to begin reading 26 | * size .......... is the size of the transfer. 27 | * stride ........ is the distance, in size units, to space the async reads. 28 | * max ........... is the max size of the file to be read. 29 | * depth ......... is the number of async operations to perform. 30 | * 31 | * 3. Call end_async(gc) when finished. 32 | * Where: 33 | * gc ............ is the pointer on the stack. 34 | * 35 | * To use model #2: 36 | * 1. Call async_init(&pointer_on_stack,fd,direct_flag); 37 | * The fd is the file descriptor for the async operations. 38 | * The direct_flag sets VX_DIRECT 39 | * 2. Call async_read(gc, fd, &ubuffer, offset, size, stride, max, depth) 40 | * Where: 41 | * gc ............ is the pointer on the stack 42 | * fd ............ is the file descriptor 43 | * ubuffer ....... is the address of a pointer that will be filled in 44 | * by the async library. 45 | * offset ........ is the offset in the file to begin reading 46 | * size .......... is the size of the transfer. 47 | * stride ........ is the distance, in size units, to space the async reads. 48 | * max ........... is the max size of the file to be read. 49 | * depth ......... is the number of async operations to perform. 50 | * 51 | * 3. Call async_release(gc) when finished with the data that was returned. 52 | * This allows the async library to reuse the memory that was filled in 53 | * and returned to the user. 54 | * 55 | * 4. Call end_async(gc) when finished. 56 | * Where: 57 | * gc ............ is the pointer on the stack. 58 | * 59 | * To use model #1: (WRITES) 60 | * 1. Call async_init(&pointer_on_stack,fd,direct_flag); 61 | * The fd is the file descriptor for the async operations. 62 | * 63 | * 2. Call async_write(gc, fd, ubuffer, size, offset, depth) 64 | * Where: 65 | * gc ............ is the pointer on the stack 66 | * fd ............ is the file descriptor 67 | * ubuffer ....... is the address of the user buffer. 68 | * size .......... is the size of the transfer. 69 | * offset ........ is the offset in the file to begin reading 70 | * depth ......... is the number of async operations to perform. 71 | * 72 | * 4. Call end_async(gc) when finished. 73 | * Where: 74 | * gc ............ is the pointer on the stack. 75 | * 76 | * Notes: 77 | * The intended use is to replace calls to read() with calls to 78 | * async_read() and allow the user to make suggestions on 79 | * what kind of async read-ahead would be nice to have. 80 | * The first transfer requested is guarenteed to be complete 81 | * before returning to the caller. The async operations will 82 | * be started and will also be guarenteed to have completed 83 | * if the next call specifies its first request to be one 84 | * that was previously performed with an async operation. 85 | * 86 | * The async_read_no_copy() function allows the async operations 87 | * to return the data to the user and not have to perform 88 | * a bcopy of the data back into the user specified buffer 89 | * location. This model is faster but assumes that the user 90 | * application has been modified to work with this model. 91 | * 92 | * The async_write() is intended to enhance the performance of 93 | * initial writes to a file. This is the slowest case in the write 94 | * path as it must perform meta-data allocations and wait. 95 | */ 96 | 97 | #include 98 | #include 99 | #if defined(solaris) || defined(linux) || defined(SCO_Unixware_gcc) 100 | #else 101 | #include 102 | #endif 103 | #include 104 | #include 105 | #ifndef bsd4_4 106 | #include 107 | #endif 108 | #ifdef VXFS 109 | #include 110 | #endif 111 | 112 | #if defined(OSFV5) || defined(linux) 113 | #include 114 | #endif 115 | 116 | #if defined(linux) 117 | #include 118 | #include 119 | #include 120 | #endif 121 | 122 | #if ((defined(solaris) && defined(__LP64__)) || defined(__s390x__)) 123 | /* If we are building for 64-bit Solaris, all functions that return pointers 124 | * must be declared before they are used; otherwise the compiler will assume 125 | * that they return ints and the top 32 bits of the pointer will be lost, 126 | * causing segmentation faults.
