MGARD: MultiGrid Adaptive Reduction of Data
As noted in #189, MGARD does not build with AppleClang 14.0.3.14030022: ``` tests/src/test_compressors.cpp:128:76: error: cannot initialize a parameter of type 'long *' with an lvalue of type 'std::int64_t *const' (aka...
Hi. I'm trying to compress turbulence flow data but when the tolerance is small like under 0.00001 compression ratio goes under 1 , which means the compressed data is bigger...
I am doing some compression studies that involve difficult-to-compress (even incompressible) data. Consider the chaotic data generated by the logistic map _x__i_+1 = 4 _x__i_ (1 - _x__i_): ``` #include...
Hi MGard developers, I'm planning to run some experiments to evaluate 1) the rate-distortion and 2) the CPU performance of MGard. Could you provide guidance on 1. which version of...
[ERR] MemoryManager::Malloc1D error. [mars01:187617:0:187617] Caught signal 11 (Segmentation fault: address not mapped to object at address 0x37) BFD: Dwarf Error: found dwarf version '5', this reader only handles version 2,...
These commits * refactor the original Huffman coding implementation, * add regression tests for `huffman_encoding`, `huffman_decoding`, `compress_memory_huffman`, and `decompress_memory_huffman`; * remove the timing statements for `compress_memory_huffman`; * add new Huffman...
This was broken on Mac with mgard_x serial option enabled.
When the lossless compressor is set to `CPU_HUFFMAN_ZLIB` in the header, Huffman coding is not applied to the quantized coefficients before they are passed to `compress_memory_z`. See [this case][`CPU_HUFFMAN_ZLIB` case]....
In #189 we are investigating how MGARD performs on some very noisy data. When this data is compressed with a tight error tolerance and then decompressed, we get an error...
Hello, I am testing the high level APIs on a V100 GPU (Summit) with a very simple benchmark. The input data is generated from random numbers between (0, 1). I...
