Dear all,
I am using a workstation with ubuntu 20.04 and with two k620 Quadro Nvidia graphic cards installed on it, and I had installed driver for the cards previously from the Ubuntu repository. Recently I installed the Cuda tool kit (available on the ubuntu repository). And I downloaded Cuda enabled namd 2.14 binary (Linux-x86_64-multicore-CUDA<https://www.ks.uiuc.edu/Development/Download/download.cgi?UserID=&AccessCode=&ArchiveID=1625> (NVIDIA CUDA acceleration). But when I am trying to run the simulation, I am getting the following error:
FATAL ERROR: CUDA error cudaMalloc(pp, sizeofT*(*curlen)) in file src/CudaUtils.C, function reallocate_device_T, line 130
on Pe 0 (param-HP-Z440-Workstation device 0 pci 0:2:0): out of memory
[Partition 0][Node 0] End of program
I am using the following command to run the simulation.
namd2 +idlepoll benchmark_gpu.conf > benchmark_gpu.log
Please help me to sort out this error.
thanks in advance
regards
shivam
