I see. After using the above parameters, it works now. Thanks.

I got another problem related with this. If I use SZ_Init_Params instead of SZ_Init(file), I have no compression with PW_REL. It works with REL or ABS.
I used the following code for init:
sz_params sz;
memset(&sz, 0, sizeof(sz_params));
sz.max_quant_intervals = 65536;
sz.quantization_intervals = 0;
sz.dataEndianType = LITTLE_ENDIAN_DATA;
sz.sysEndianType = LITTLE_ENDIAN_DATA;
sz.sol_ID = SZ;
sz.layers = 1;
sz.sampleDistance = 100;
sz.predThreshold = 0.99;
sz.offset = 0;
sz.szMode = SZ_BEST_COMPRESSION; //SZ_BEST_SPEED; //SZ_DEFAULT_COMPRESSION;
sz.gzipMode = 1;
sz.errorBoundMode = PW_REL; //REL; //PW_REL;
sz.absErrBound = 1E-4;
sz.relBoundRatio = 1E-3;
sz.psnr = 80.0;
sz.pw_relBoundRatio = 1E-2;
sz.segment_size = 32;
sz.pwr_type = SZ_PWR_MIN_TYPE;
SZ_Init_Params(&sz);
