Nest compile on Piz-Daint
by Sergio Solinas 17 Feb '21

17 Feb '21

Dear NEST Users, I'm trying to get NEST up and running on Piz-Daint. I could manage to have it fully compiled and installed with python bindings, MPI, GSL and Boost. However, simulations start but get killed returning a std::bad_alloc. make installcheck also fails. Did anyone managed to have it installed on this HPC?

Hi all, I am writing a new neuron model using nestml and then I modify the C++ code. I am having a hard time defining an input parameter of the neuron as an array of numbers. Is this even possible? Thanks. Regards Cristiano

by Itaru Kitayama 08 Feb '21

Hi, The NEST "Read the Docs" tells us how to invoke doxygen, but I am wondering if the community continuously builds Doxygen db every time a series is committed to master and put it somewhere.

Spike Event Multiplicity
by Benedikt Feldotto 04 Feb '21

04 Feb '21

Dear all, I realized that spikes that pass synapses (e.g. stdp_connection) are not processing a "multiplicity" value. However, some other nodes e.g. spikes delivered from the volume_transmitter into the stdp_dopa_connection include such a value. Does this mean, the multiplicity for spike events that pass a synapse is always equal to 1? Thanks! Best Regards, Benedikt -- Benedikt Feldotto M.Sc.

CBD Online
by brielleyoung31＠gmail.com 20 Jan '21

20 Jan '21

If you are thinking of starting a CBD product business, then you should get to know the different CBD products on the market. Cannabidiol, also called cannabidiol, is a powerful phytochemical found in nature. It's one of only 47 known compounds that produce delta-9-tetrahydrocannabinol (THC) in plants. The good news is that scientists have successfully bred several strains of plants that contain cannabidiol and made it usable as a food supplement. Some of these strains are even available online, which makes it easier for people to try out new products that they haven't tried before. Unfortunately, not every CBD product is created equal. It's important to understand the differences between these strains so that you can get a better understanding of which ones will be the most effective when used as dietary supplements. Take some time to learn more about these CBD products, because there is an abundance of information available at https://goldbee.com/. A good way to start is by looking at the ingredients. Most of the CBD products available today are derived from a variety of different sources. Some sources include hemp, the leaves of hemp, and other plants. Other sources are not as reliable, such as hemp seed oil, hemp hurd, and other plant parts. Take the time to learn about the various components of each CBD product so that you can make a more informed decision. One of the best natural compounds found in CBD products is cannabidiol. This substance is often used interchangeably with cannabigerol. While cannabidiol has been shown to have a number of health benefits, it has also been shown to produce some of the same side effects as other substances. In some instances, it has been shown to cause depression, and it has also been linked to memory loss and muscle weakness. This substance has also been banned in several countries because of its possible side effects. It's important to note that some clinical trials have shown positive results with this compound. However, there are still many questions surrounding this herb. It's important that you understand why it is important to have clinical trials conducted on CBD products. If the medical community is able to determine the full potential for CBD, then it will help them come up with better medications. There may come a time when it will be possible to develop a CBD pill that produces the same positive results without the dangerous side effects. With that said, it's important that you research different CBD products so that you're ready to enter the world of natural medicine. There are a lot of different options out there that offer great products that can help you combat a wide range of conditions. Take some time to get familiar with all of your options, and then you will be ready to get started.
