Read a chunk of - * dataset of an HDF5 file with an integer array on SRB server, - * using hyperslab. - * Usage: The HDF5 is built on the top of SRB. So you just need to - * activate a connection to SRB server by calling function - * H5Pset_fapl_srb()(after creating file property list by calling - * H5Pcreate()). All server information is passed in through its - * parameter SRB_Info(a structure). Its fields are - * char *srbHost: SRB host address of server. If the input is - * NULL, it will use the environment varible "srbHost" if - * it is defined. If it is not defined, the - * ~/.srb/.MdasEnd file will be checked next. If not, it - * will use the hostname of the client machine. - * char *srbPort: SRB host port number of server. If the - * input value is NULL, it will use the env variable - * "srbPort" if it is defined. If not, it defaults to - * 5558. - * char *srbAuth: SRB Authentication-password. It is used to - * define password for MDAS or SEA authentication. - * For SEA authentication, this is the password used by - * the SEA library to decrypt the encrypted private key - * stored in the file ~/.SEAuuuuu@ddddd(where uuuuu is - * the user ID and ddddd is the user domain name). This - * input is not needed if an unencrypted private key is - * available in the /tmp directory(generated using the - * 'seaauth auto' command). To provide additional - * flexibility, a client may also use the environment - * variable "srbAuth" to specify the password. A client - * may also supply the password in the ~/.srb/.MdasAuth - * file. If a client uses more than one method to specfy - * the password, the value given in this function call - * will take precedent, then the environment variable - * "srbAuth", and lastly, the ~/.srb/.MdasAuth file. - * int storSysType: Storage system type on SRB server. - * 0=Unix, 1=UniTree, 2=HPSS, 3=FTP, 4=HTTP - * int mode: File access mode, same definition with Unix. - * int size: File Size, only valid for HPSS, -1 is default - * - * Then you can open an HDF5 file by calling H5Fopen(). When - * you pass in the file name, it has to be file name with an - * absolute path. It you use SDSC server(ghidorah.sdsc.edu), your - * home directory is possibly in /projects/mdas/srb/SRBVault/. - */ -#include "h5test.h" - -#ifndef H5_HAVE_SRB -int main(void) -{ - printf("Test skipped because SRB driver not available\n"); - return 0; -} -#else - -#define fileName "/projects/mdas/srb/SRBVault/slu.ncsa/a.h5" -#define DATASETNAME "IntArray" -#define NX_SUB 3 /* hyperslab dimensions */ -#define NY_SUB 4 -#define NX 7 /* output buffer dimensions */ -#define NY 7 -#define NZ 3 -#define RANK 2 -#define RANK_OUT 3 - -int main(void) -{ - hid_t fapl=-1, fid = -1, dataset; - hid_t datatype, dataspace; - hid_t memspace; - H5T_class_t class; /* data type class */ - H5T_order_t order; /* data order */ - size_t size; /* - * size of the data element - * stored in file - */ - hsize_t dimsm[3]; /* memory space dimensions */ - hsize_t dims_out[2]; /* dataset dimensions */ - herr_t status; - - int data_out[NX][NY][NZ ]; /* output buffer */ - - hsize_t count[2]; /* size of the hyperslab in the file */ - hssize_t offset[2]; /* hyperslab offset in the file */ - hsize_t count_out[3]; /* size of the hyperslab in memory */ - hssize_t offset_out[3]; /* hyperslab offset in memory */ - int i, j, k, status_n, rank; - SRB_Info srb_info={ NULL, /* Use host name in ~/.srb/.MdasEnv */ - NULL, /* Use environment variable "srbPort" */ - NULL, /* Use password in ~/.srb/.MdasEnv */ - 0, /* Use Unix storage system. */ - 0600, /* File was created for read and write for - * owner */ - -1 /* default */ - }; - - for (j = 0; j < NX; j++) { - for (i = 0; i < NY; i++) { - for (k = 0; k < NZ ; k++) - data_out[j][i][k] = 0; - } - } - - fapl = H5Pcreate(H5P_FILE_ACCESS); - if (fapl < 0) { - printf (" H5Pcreate failed. \n"); - return -1; - } - - status = H5Pset_fapl_srb(fapl, srb_info); - if (status < 0) { - printf ("H5Pset_fapl_srb failed. \n"); - return -1; - } - - fid = H5Fopen(fileName, H5F_ACC_RDONLY, fapl); - if (fid < 0) { - printf ("H5Fopen failed. \n"); - return -1; - } - dataset = H5Dopen(fid, DATASETNAME); - if(dataset<0) { - printf ("H5Dopen failed. \n"); - return -1; - } - /* - * Get datatype and dataspace handles and then query - * dataset class, order, size, rank and dimensions. - */ - datatype = H5Dget_type(dataset); /* datatype handle */ - class = H5Tget_class(datatype); - if (class == H5T_INTEGER) printf("Data set has INTEGER type \n"); - order = H5Tget_order(datatype); - if (order == H5T_ORDER_LE) printf("Little endian order \n"); - - size = H5Tget_size(datatype); - printf(" Data size is %d \n", size); - - dataspace = H5Dget_space(dataset); /* dataspace handle */ - rank = H5Sget_simple_extent_ndims(dataspace); - status_n = H5Sget_simple_extent_dims(dataspace, dims_out, NULL); - printf("rank %d, dimensions %lu x %lu \n", rank, - (unsigned long)(dims_out[0]), (unsigned long)(dims_out[1])); - - /* - * Define hyperslab in the dataset. - */ - offset[0] = 1; - offset[1] = 2; - count[0] = NX_SUB; - count[1] = NY_SUB; - status = H5Sselect_hyperslab(dataspace, H5S_SELECT_SET, offset, NULL, - count, NULL); - - /* - * Define the memory dataspace. - */ - dimsm[0] = NX; - dimsm[1] = NY; - dimsm[2] = NZ ; - memspace = H5Screate_simple(RANK_OUT,dimsm,NULL); - - /* - * Define memory hyperslab. - */ - offset_out[0] = 3; - offset_out[1] = 0; - offset_out[2] = 0; - count_out[0] = NX_SUB; - count_out[1] = NY_SUB; - count_out[2] = 1; - status = H5Sselect_hyperslab(memspace, H5S_SELECT_SET, offset_out, NULL, - count_out, NULL); - - /* - * Read data from hyperslab in the file into the hyperslab in - * memory and display. - */ - status = H5Dread(dataset, H5T_NATIVE_INT, memspace, dataspace, - H5P_DEFAULT, data_out); - for (j = 0; j < NX; j++) { - for (i = 0; i < NY; i++) printf("%d ", data_out[j][i][0]); - printf("\n"); - } - /* - * 0 0 0 0 0 0 0 - * 0 0 0 0 0 0 0 - * 0 0 0 0 0 0 0 - * 3 4 5 6 0 0 0 - * 4 5 6 7 0 0 0 - * 5 6 7 8 0 0 0 - * 0 0 0 0 0 0 0 - */ - - /* - * Close/release resources. - */ - H5Tclose(datatype); - H5Dclose(dataset); - H5Sclose(dataspace); - H5Sclose(memspace); - H5Fclose(fid); - H5Pclose(fapl); - - printf("Test finished!\n"); - return 0; -} - -#endif |
