Cuda memory problem

[NiranjanRavi05]

Hello,

I am using CuSZ compressor in my research work. I was able to run the example file capi.cu for CESM data, but when I altered it and ran for my own dataset, i got an error:

terminate called after throwing an instance of 'thrust::system::system_error'
what(): copy_if failed to synchronize: cudaErrorIllegalAddress: an illegal memory access was encountered
Aborted (core dumped)

I am running it in the GPU - Tesla V100.

commands executed:
To build SZ:
mkdir build && cd build
cmake .. -DCUSZ_BUILD_EXAMPLES=on -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTING=on -DCMAKE_CUDA_ARCHITECTURES="70" -DCMAKE_PREFIX_PATH=/usr/local/cuda-11.7/targets/x86_64-linux/lib/cmake -DCMAKE_INSTALL_PREFIX=main
make
make install
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mnt/tank/bem-nr/cuSZ-develop/build

To compile capi.cu:
nvcc -o capi capi.cu -I/mnt/tank/bem-nr/cuSZ-develop/include -I/usr/local/cuda-11.7/include -L/usr/local/cuda-11.7/lib64 -lcudart -L/mnt/tank/bem-nr/cuSZ-develop/build -lcusz --extended-lambda -g
for CESM data: ./capi /data/cesm-CLDHGH-3600x1800
for my data set: ./capi /data/mydata

My dataset file is a binary file with floating point values in 1D array (length - 1x89999991)

I tried altering the length of my array, same as CESM data. But got the same error.

Can you please tell me why CuSZ is giving me this error? Please let me know if you need further information.

Thanks in advance!
