Simulator: Single-shot computation for vbm images hangs with no further progress #473

Closed hvgazula closed 6 years ago

hvgazula commented 6 years ago

Problem

The code for this issue is at https://github.com/MRN-Code/ssr_test_vbm_multiple_sites and should work fine in its current state. However, when we comment out the following line https://github.com/MRN-Code/ssr_test_vbm_multiple_sites/blob/master/local.py#L54, implying running a regression on all voxels of the images, the simulator hangs.

Similar issue can be replicated with the decentralized regression with normal equation at https://github.com/MRN-Code/coinstac_drne_vbm_mcic/blob/master/local.py#L25

and with the multi-shot regression by commenting the following line https://github.com/MRN-Code/coinstac_msr_vbm_mcic/blob/master/local.py#L26-L27
