Thanks for your interest in using YASK!
This particular "error" is a normal exception caused by not enough memory on the platform.
Try freeing up memory or running with a smaller problem-size by reducing the "-d" knob arguments.

Thanks for posting the log file--this was indispensable for quickly finding the root-cause. See the following (comments added):
MemTotal: 16421840 kB ## There are16 GiB on this machine...
MemFree: 4509888 kB ## ...but only about 4.5 GiB free...
MemAvailable: 12199044 kB ## ...and 12 GiB available.
...
Allocating 14.027GiB for 3 grid(s) using default allocator...
YASK Kernel: error: cannot allocate 14.027GiB. ## Needs 14 GiB.

Thanks for the reply. I thought it was a disk space free error.
